Woolies CEO quits after disaster interview

Woolworths chief executive Brad Banducci has announced his retirement amidst a flurry of challenges facing the Australian supermarket behemoth. As the company grapples with a staggering loss and contends with allegations of price gouging and unfair dealings with suppliers, the announcement of Banducci's departure marks a significant shake-up at the top. The supermarket giant wasted no time in appointing a successor, promoting Amanda Bardwell to the coveted position after what was described as an "extensive international search process". Bardwell, a veteran of the company with 23 years of experience, currently leads WooliesX, a vital sub-division within Woolworths. Banducci's retirement comes hot on the heels of Woolworths' latest financial results, which revealed a substantial $781 million statutory loss. This loss was largely attributed to a $NZ1.6 billion ($1.5 billion) writedown in the value of its New Zealand grocery business and a $209 million reduction in the value of its stake in ASX-listed alcohol and hotels spin-off Endeavour. Despite these setbacks, Woolworths managed to announce a 2.5 per cent rise in half-year profit to $929 million, buoyed by a 4.4 per cent increase in revenue compared to the previous year. However, amidst these financial intricacies lies a more troubling narrative. Woolworths has found itself embroiled in allegations of price gouging and unfair practices with suppliers, casting a shadow over its operations. The spotlight intensified with the release of an ABC investigation featuring a contentious interview between Banducci and reporter Angus Grigg. The interview, part of a comprehensive examination of the Australian supermarket industry amid the ACCC's investigation into allegations of unfair pricing, saw Banducci visibly flustered and defensive. The program scrutinised how supermarkets profit from rising prices amid a cost of living crisis and included conversations with key industry figures, including Banducci and Coles boss Leah Weckert. Banducci's exchange with Grigg, particularly his dismissal of former ACCC head Rod Sims' remarks, underscored the tension surrounding the allegations. Banducci's subsequent request to edit his comments mid-interview, followed by a brief exit to confer with his PR team, highlighted the sensitivity of the issue. Grigg, reflecting on the incident, described Banducci's reaction as "pretty startling", while pointing out that the lack of scrutiny faced by supermarket executives over the years was very significant.

Spin cycle disaster: man puts winning Lotto ticket through the wash

In a harrowing tale that's sure to wring out a chuckle or two, a man in his late 20s from Belmont, Western Australia, narrowly escaped laundering his way out of a $2.8 million windfall – after nearly sacrificing his winning lottery ticket to the treacherous depths of his washing machine. It all started innocently enough at the Here's Luck Lottery Centre in Belmont Forum, where our hero – who very sensibly prefers to remain incognito – purchased what would turn out to be a life-changing ticket for the Saturday Lotto. Little did he know, his unassuming trousers would soon become the epicentre of a near-catastrophe. In a classic case of absentmindedness, our hero forgot to take his ticket out of his pants pocket before succumbing to the siren song of laundry day. "I forgot to take the ticket out of my trousers and put it in the washing machine," confessed the forgetful winner. "After five minutes I realised and stopped the washing machine to grab the ticket, fortunately, it was safe." Indeed, it was a race against the spin cycle as the man scrambled to rescue his potential fortune from a soapy demise. "I couldn’t think, I couldn’t sleep, I am still processing the win," he admitted with palpable relief. But our protagonist emerged victorious from this sudsy saga, managing to salvage his ticket just in the nick of time. With a sigh of relief, he made his way to Lotterywest HQ to claim his well-deserved prize. Lotterywest spokesman James Mooney chimed in, highlighting the importance of registering tickets to avoid potential mishaps of this magnitude. "For this player, it all came out of the wash okay, but it’s a reminder for players to register their ticket to prevent what could be a multimillion-dollar mistake," he wisely advised. Image: Getty

"Absolute f***ing disaster": The Block presenter slams former contestants

Shelley Craft has ripped into two former contestants of The Block, saying the team was an "absolute f***ing disaster". The Block presenter was chatting candidly about the formula of the show on Hit radio show Breakfast with Maz & Matty, where she described what she thought was the ultimate pairing for a team to partake in the renovation show. Shelley was asked about the calibre of contestants on the upcoming season, admitting that the show’s producers generally cast for “characters,” rather than previous experience. “I always thought the best team would be an accountant and an HR manager, because you have to be able to manage your money and manage your trades,” she said, revealing her own personal pick for a successful team. “[But] we sort of had that last year and it was an absolute f***ing disaster. That was the worst team that there is, it’s not the recipe!” she continued, to laughter from the radio hosts. “We’re really after great people that are happy to give it everything they’ve got, and we’ve got five teams this year who are ready to give it a red hot crack.” The “disaster” Craft is referring to is last year’s most controversial couple, lawyer-turned actor Sharon and her accountant husband Ankur, who copped a fierce backlash from viewers over their apparent negative attitudes while filming The Block. The couple repeatedly clashed with their builders, foremen Keith and Dan and host Scott Cam, and also declared on camera numerous times that they wished they’d never signed up to do the show. The couple even had their finances frozen by Scott Cam due to their apparent inability to manage their budget during the intense renovation project. Sharon and Ankur later said they felt “ambushed” and were upset at how they’d been portrayed on the show, prompting Cam to later say in an interview that he thought the couple had “made [the experience] harder” on themselves than it needed to be.

6 cruise ship disasters

While a cruise nowadays is a safe way to explore the world in consummate luxury, in the early days catching a cruise ship was by no means smooth sailing. Here are 6 cruise ship disaster stories. 1. The Titanic After colliding into an iceberg somewhere in the North Atlantic the “unsinkable” Titanic sank two miles to the bottom of the ocean. More than 1,500 lives were lost, with the disaster continuing to intrigue. 2. S.S. Eastland In 1915 Western Electric hosted an employee picnic aboard the S.S Eastland on the Chicago River which took an unfortunate turn when the ship tipped over (while still at the dock!). 3. The Norwegian Dawn In a journey between New York City and the Bahamas, The Norwegian Dawn was hit by a 70-foot wave that ended up flooding 62 cabins. Thankfully only two people suffered minor injuries. 4. The Splendor On a seven-day cruise to Mexico the engine room of the Splendor caught fire. The cruise was shortened to three days, and 3,299 passengers didn’t have access to toilets for 13 hours. 5. The Costa Concordia The Costa Concordia unfortunately sank in 2012, after the ship hit shallow seas off the coast of Italy. Navy divers reportedly used explosives to access the inside of the ship, and managed to refloat the vessel to dismantle the wreckage. 32 lives were lost. 6. Carnival Conquest Well, we’re just going to have to take their word for it, but apparently the Carnival Conquest ship is haunted by a tall man in a trench coat, who appears in the middle of the night.

Disaster, opulence, and the merciless ocean: why the Titanic disaster continues to enthral

<a href="https://theconversation.com/profiles/kristie-patricia-flannery-1220337">Kristie Patricia Flannery</a>, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a> The question on many minds this week is why did some of the world’s richest men risk death to venture to the bottom of the sea in a cold and cramped <a href="https://www.nytimes.com/2023/06/20/us/oceangate-titanic-missing-submersible.html">“experimental” submersible</a> for a chance to glimpse the wreck of the Titanic? The “unsinkable” ship that sunk on its maiden voyage across the Atlantic in 1912 after colliding with an iceberg is arguably the world’s most well-known boat. The Titanic is recognisable to more of the world’s population than, say, the Niña, the Pinta, and the Santa Maria (Christopher Colombus’s fleet that launched the Spanish conquest of the Americas), or Captain Cook’s HMS Endeavour (the tall ship that set in motion the British conquest of Australia). The Endeavour’s long-forgotten wreck was found scuttled off the coast of Rhode Island <a href="https://theconversation.com/has-captain-cooks-ship-endeavour-been-found-debate-rages-but-heres-whats-usually-involved-in-identifying-a-shipwreck-176363">just last year</a>. The Titanic’s maiden voyage and calamitous end was one of the biggest news stories of 1912, and has continued to fascinate us ever since. The disaster inspired songs and multiple films in the twentieth century, including James Cameron’s 1997 epic romance, which long reigned as the <a href="https://en.wikipedia.org/wiki/List_of_highest-grossing_films#Timeline_of_highest-grossing_films">highest-grossing film of all time</a>. More recently, Titanic exhibitions that invite visitors to examine relics and <a href="https://titanicexhibition.com/nyc/#sec_instafeed">explore the ship’s recreated rooms have attracted huge crowds in New York, Seville and Hong Kong</a>. <h2>Opulence and immigrants</h2> There are two reasons why we are so drawn to the Titanic, and why the super-rich are apparently willing to part with their money and even risk their lives to catch a glimpse of its broken hull. The first is its opulence. The White Start Line that built the Titanic advertised the ship as the most luxurious ever to set sail. Wealthy passengers paid up to £870 for the privilege of occupying the Titanic’s most expensive and spacious first-class cabins. To put this 110-year-old money in perspective, when the first world war broke out in 1914, infantry soldiers in the British army were paid a basic salary of around £20 per year. Titanic movies and exhibitions are popular because audiences enjoy the voyeurism of gazing on the ship’s beautiful furnishings, the stunning clothes worn by its rich and beautiful passengers, and their elaborate meals in fancy restaurants. First-class passengers feasted on <a href="https://online.ucpress.edu/gastronomica/article-abstract/9/4/32/93511/The-Night-the-Good-Ship-Went-Down-Three-Fateful">multi-course dinners</a> with salmon, steak, and pâté de foie gras. Chefs in Australia and around the globe occasionally <a href="https://www.timeout.com/melbourne/things-to-do/titanic-dining-experience">recreate Titanic meals</a> for curious clients. Hundreds of poor immigrant passengers, represented by Jack (played by Leonardo DiCaprio) in Cameron’s movie, were also aboard the Titanic. They lived in crowded quarters and enjoyed less thrilling meals such as boiled beef and potatoes. If their ilk were the only people on board the Titanic, the ship would arguably have faded quickly from memory. <figure><iframe src="https://www.youtube.com/embed/erAQ9LkftwA?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <h2>The power of the sea</h2> The fact the Titanic was touted as unsinkable also adds to its allure. The ship, whose name evoked its massive size, was engineered to cheat the ocean. When it departed England it symbolised man’s domination over nature. At the bottom of the Atlantic, it serves as a visceral reminder of the indomitable sea’s awesome power. The same two factors - the excess of the voyage, and its defeat by the sea – are now driving the current global interest in the Titan submersible disaster. Few world events garner so much attention, including statements from Downing Street and the White House, and live news blogs from The New York Times and the Guardian. The Titan, like the Titanic, commands our attention because of its obscenely rich passengers, who each reportedly paid US$250,000 (or between four and five times the average US salary) to visit the wreck of the famous ship that battled the sea and lost. And then there is the intriguing mystery and power of the sea. News outlets are publishing helpful graphics that try to teach our terrestrial brains to comprehend just how deep the ocean is, and how far below the sea’s surface the Titanic and possibly the Titan lie. <h2>The limits of human knowledge</h2> Last night I spied <a href="https://neal.fun/deep-sea/">Neal Argawal’s Deep Sea</a> website circulating on social media. The site allows viewers to scroll from the sea surface to the sea floor, diving down past images of various marine animals that inhabit different oceanic depths. At 114 metres is an orca, and 332m marks the the deepest depth a human has ever reached using SCUBA gear. It takes a lot of scrolling to descend to the Titanic almost 4,000m below the waves. Besides gross income inequality, reflecting on the Titan and the Titanic invite us to confront just how little we can “see” of the sea in this age of mass surveillance. Not even the powerful US navy, assisted by the Canadian, UK and French governments, can muster the resources and technology required to locate, let alone rescue, the missing submersible. As the sea seems to have swallowed yet another ship, we are reminded of limits of human knowledge and mastery over the ocean.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/208200/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/kristie-patricia-flannery-1220337">Kristie Patricia Flannery</a>, Research Fellow, Institute for Humanities and Social Sciences, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Eerie link between OceanGate pilot and Titanic disaster

A chilling link has been discovered between pilot Stockton Rush, who was onboard the OceanGate submersible, and the Titanic disaster in 1912. Mr Rush, who was at the helm of the vehicle bound for the Titanic wreckage, has a personal connection to two of the victims who were onboard the Titanic when it sank over 100 years ago. His wife, Wendy Rush, is the great-great-granddaughter of Isador Straus, who co-founded Macy’s department store, and Ida Straus, who were among the wealthiest people aboard the Titanic’s ill-fated transatlantic voyage, according to archived records obtained by the New York Times. The Strauses have long been remembered for their display of love and affection when the ocean liner hit the iceberg before infamously sinking in the North Atlantic, claiming the lives of more than 1500 people. Survivors of the disaster reported seeing Ida refuse a place on the lifeboats, which were reserved largely for women and children, and decided to stay onboard the sinking vessel with her husband of more than 40 years. Their tragic love story was depicted in James Cameron’s fictionalised version of the tragedy, his 1997 blockbuster Titanic, which features a scene showing an elderly couple holding on to each other in bed as waters rise around them. Wendy Rush is descended from one of the couple’s daughters, Minnie Strauss, who married Dr. Richard Weil in 1905, and their son, Richard Weil Jr., served as president of Macy’s New York, His son, Dr. Richard Weil III, is Wendy Rush’s father, Joan Adler, the executive director of the Straus Historical Society. Isador’s body was found at sea weeks after the Titanic sank, but his wife’s body was never recovered. Wendy also worked for OceanGate as their communications director, with her LinkedIn indicating she had been on several trips to the wreckage of the Titanic herself. The OceanGate submersible <a href="https://oversixty.com.au/news/news/surprising-cause-of-death-revealed-for-missing-titan-sub-crew" target="_blank" rel="noopener">reportedly imploded</a> hours after it went missing, with all five people on board believed to be dead.

4 worst travel disasters and how to avoid them

After all the stress involved in preparing and booking an overseas trip, it can be quite disheartening for something to go wrong while you’re on holidays aboard. With a bit of planning however, you can be sure that even if you fall victim to one of these travel disasters you’ll be in a good position to continue your trip. Here are four of the worst travel disasters, and how to avoid them. These travel disasters can easily turn the trip of a lifetime into one that you’d rather forget. 1. Missed flight The prospect of running through a crowded terminal only to be greeted by a closed door at the gate is one that sinks the heart of even the most nonchalant traveller. And missing a flight can really throw a spanner in the works for your travel plans. If your plane has taken off without you, it’s recommended that you immediately go to your airline’s desk who can get you on the next flight. Whether or not you will have to pay for this is another matter entirely, and depends on who’s at fault for the missed flight. The best safeguard in this case, is having travel insurance that covers you for missed connections. 2. Lost luggage There’s few feelings in the world of travel that are worse than the one you get hours after disembarking from your flight, standing at a now-empty baggage carousel, and knowing that two weeks of holiday clothing is anywhere in the world but here. Make sure you hang onto your baggage ticket and if this ever happens head to counter or office at your airport and fill out a missing baggage form. If your bag has indeed been lost or damaged and the airline is at fault you may be compensated, but it’s another one of those circumstances where it is just best to have travel insurance to make sure you’re prepared. 3. Becoming sick From cold to migraines to something more serious, there is nothing in the world that ruins your dream trip like becoming sick. If you have fallen ill overseas it’s recommended you seek medical assistance as soon as possible. In some countries you may have to pay for your treatment upfront, and if this is the case then you may have to contact your travel insurance provider (they generally have 24 hour contact centres) to arrange payments. If you don’t have insurance and are in a situation where you have to pay for treatment upfront you must contact your financial institution or a family member. 4. Lost passport Opening your daypack only to find your passport missing is every traveller’s worst nightmare. If this has happened to you, it’s important to contact the local police and then the New Zealand embassy, who will be able to provide you with an emergency passport so you can return home. Carry an extra copy of your passport in a separate part of your luggage. Images: Getty

Bride’s online dress disaster

Bride-to-be Zuzanna was full of excitement ahead of her engagement party - she was free of stress, and she had an amazing dress … until she didn’t. Zuzanna had been under the impression that her Amazon find - a gorgeous white lace maxi dress with nearly 3000 promising reviews - was going to be everything she dreamed. But that dream was destined to become a nightmare, with the online retail supergiant sending her a much shorter version of the garment. Gone was any vision of a long skirt swirling around her ankles as she strode in to her upcoming engagement party, with the new hem barely grazing Zuzanna’s knees in a picture she posted to Facebook group What I Asked For VS What I Got. “It’s not a bad dress at all,” she wrote, “but it’s really not what I was going for.” Continuing from there, Zuzanna took the opportunity to warn others who might have had the same idea as her, pleading for them to “be careful what you order. I bought this dress for my engagement party on Saturday … I definitely will not be wearing it!” She then explained that it had taken her by surprise to open her package and made the unexpected discovery, as the reviews for the product had been so positive. Her misfortunes weren’t to end there, however, with Zuzanna noting that the dress’ “material is super cheap feeling, but I feel like I could have worn it once before it fell apart in the wash.” She hadn’t had any problems with her Amazon purchases before, and hadn’t even considered that poor outcome, though it now meant she’d have to go out in search of another dress for her party. “I don’t hate the dress,” she surmised, “it's just not right for the occasion and that's so sad.” And although Zuzanna seemed to have come to terms with her fate, and didn’t seem too upset about it, people in the comments still wanted to offer her their support, with a few suggestions on how she should proceed with Amazon. “They have a short dress on the site, they probably scanned the wrong item when they sent it to you,” one said. 'It's probably a mistake,” another wrote, before sharing that they actually “had several of these maxi dresses” and that Zuzanna should try contacting the company. Meanwhile, others seized the opportunity for some fun, with one asking “where's the other half of the dress?” “Wow,” said another, “you must be really tall!” Images: Facebook

Only days left for one Aussie state's residents to make $1000 claim

New South Wales residents who faced the brunt of July 2022’s floods have only one week remaining to claim their $1000 lump sum payment. Prime Minister Anthony Albanese announced the Disaster Recovery Payment [DRA] - of $1000 per adult and $400 per child - as he set off to tour some of the hardest hit regions in July 2022. The news gave some hope to those who had lost everything in the disaster that swept through their homes, and the chance to secure the likes of clothing, food, and temporary shelter. At the peak of the devastation, over 100 evacuation orders - amounting to roughly 85,000 people - had been issued across the state, with thousands of properties inundated, with SES crews responding to over 370 flood rescues, and a frightening 7600 help requests. People living in the local government areas [LGAs] that were directly impacted by the floods are eligible, although certain criteria must be met. Service Australia outlines that you (or a dependent child to whom you’re the principal carer) must be an Australian citizen or hold an eligible visa, be in an eligible LGA, and must be claiming the payment for the first time. Those whose homes suffered major damage due to the floods and required either repair or replacement in certain areas, as well as those whose “major assets” - the likes of caravans, vehicles, water tanks, and sheds - were also in need of repair or replacement are eligible for the payment as well. And residents who were seriously injured, or had an immediate family member (who is/was an Australian citizen) die or go missing in the floods, are also eligible. Furthermore, individuals who lost income as a direct result of the floods may be able to get the Australian Government Disaster Recovery Payment [AGDRP]. If this is the case, they are then also able to claim the DRA. As for which LGAs the payment covers, residents from the following who felt the floods’ impact should look into it: Bayside, Blacktown, Blue Mountains, Camden, Campbelltown, Canterbury Bankstown, Central Coast, Cessnock, Cumberland, Dungog, Fairfield, Georges River, Hawkesbury, Hornsby, Kempsey, Kiama, Lake Macquarie, Lithgow, Liverpool, Maitland, Mid-Coast, Muswellbrook, Nambucca Valley, Narromine, Newcastle, Northern Beaches, Oberon, Parramatta, Penrith, Port Macquarie-Hastings, Port Stephens, Randwick, Shellharbour, Shoalhaven, Singleton, Strathfield, Sutherland, The Hills, Upper Lachlan, Warren, Wingecarribee, Wollondilly, and Wollongong. New South Wales residents who are eligible only have until April 5 to make their claim. To check your eligibility status, <a href="https://www.servicesaustralia.gov.au/who-can-get-new-south-wales-floods-july-2022-australian-government-disaster-recovery-payment?context=62849">head to Service Australia</a>.

What Australia learned from recent devastating floods – and how New Zealand can apply those lessons now

Australia and New Zealand have both faced a series of devastating floods triggered by climate change and the return of the <a href="https://www.weatherwatch.co.nz/content/historic-3rd-la-nina-is-back-but-it-barely-left-us-in-the-first-place">La Niña weather pattern</a>. So it makes sense that Australia has now <a href="https://www.abc.net.au/news/2023-02-17/australia-sends-disaster-crew-to-nz-death-toll-rises/101989822">sent disaster crews</a> to help with the aftermath of Cyclone Gabrielle. With <a href="https://www.newscientist.com/article/2343938-eastern-australia-is-battling-fifth-major-wave-of-floods-in-19-months/">five serious floods</a> in the space of 19 months in 2021-2022, Australia’s experiences – and how people responded – offer New Zealand a guide for recovering and rebuilding after an extreme weather event. The flooding events in both countries share two key common elements. First, the floods broke previous records and were the largest in recent history. Second, there were also repeat flood events. In Auckland, there were <a href="https://www.odt.co.nz/news/national/residents-evacuated-homes-roads-flooded-again">two massive floods within five days</a>, while Cyclone Gabrielle became the Coromandel’s <a href="https://www.rnz.co.nz/news/national/484167/cyclone-gabrielle-thames-coromandel-already-facing-fifth-severe-weather-event-of-year">fifth severe weather event</a> for 2023 and devastated other parts of the North Island. The other common factor is urbanisation. <a href="https://www.stats.govt.nz/news/auckland-population-may-hit-2-million-in-early-2030s">Auckland’s population has been growing</a>, resulting in the increasing development of the built environment. Intensifying urban development places pressure on existing drainage systems – parts of which are no longer fit for purpose. Extensive built-up and paved areas with hard, impermeable surfaces can also cause rapid run-off during heavy rain, with the water unable to be absorbed into the ground as it would be in <a href="https://theconversation.com/auckland-floods-even-stormwater-reform-wont-be-enough-we-need-a-sponge-city-to-avoid-future-disasters-198736">soft, vegetated areas</a>. <h2>Working with the community</h2> Our <a href="https://www.youtube.com/watch?v=7En6dA-N3MA">recent research</a> in the Hunter Valley in Australia – one of the areas affected by those five successive floods – identified similar factors contributing to the flooding events, including a <a href="https://www.nsw.gov.au/sites/default/files/2020-06/Hunter%20REDS.pdf">rapidly growing regional population</a>. Two of our research sites – the Cessnock and Singleton local government areas – had growing urban centres that reflected a similar development trajectory to Auckland, albeit in a smaller scale. Our research in the Hunter Valley established the importance of identifying existing community resilience and gaps. We also observed the need to involve the community at all levels. This included having early warning systems and evacuation protocols in place to improve community access to information and warnings. The State Emergency Services (SES) is the main agency in New South Wales responsible for flood response and management. Supported by community volunteers, the SES has a clear focus at the local level. This community focus is evident with its “door-knocking kit”, which is based on a community-level vulnerability assessment. The SES has a list of those in the community who are most at risk, such as the elderly and people with disabilities. When a flood risk becomes evident, SES volunteers go knocking on doors to check their preparedness and provide evacuation support. The equivalent of SES in New Zealand, Auckland Emergency Management, could learn from this community-based approach and include it within its <a href="https://getready.govt.nz/en/involved/community/">Community Group Support</a> initiative, so that future disaster responses can be more closely tailored to the community. In the recent floods in Auckland, communication was an issue. Relaying directives and information through multiple institutional layers <a href="https://www.smh.com.au/world/oceania/some-incorrect-decisions-auckland-mayor-under-fire-over-deadly-floods-20230130-p5cggt.html">led to confusion</a>, which could have been avoided through a closer community-based approach. <h2>Building a volunteer army</h2> Another key factor in Australia is the large cadre of SES volunteers – around <a href="https://www.ses.nsw.gov.au/about-us/">9,000 in New South Wales</a>, a state with a population of just over eight million. This is a significant form of social capital, without which the current approach to flood response and management would not be possible. While there are initiatives in New Zealand to <a href="https://www.civildefence.govt.nz/get-ready/volunteering/">attract and engage volunteers</a>, more needs to be done. Civil defence needs to conduct a structural review of the existing volunteer organisations that work in the disaster and emergency response field to identify ways to improve the recruitment and retention. We also found evidence of volunteer “burn-out”, meaning there’s a need to support volunteers emotionally and financially during extended periods of disaster response and recovery. While there is a large number of SES volunteers in Australia, more are needed as climate change drives more frequent, extensive and intense disasters. Given the similar nature of repeat climate-related disaster events in New Zealand, provisions for a large cadre of well-supported and well-trained volunteers is necessary. A review of existing volunteer agencies and community organisations should be undertaken to identify ways they can be harmonised to avoid competing pressures for resources. As well, there’s a need to nurture collaboration between agencies to help with sharing skills, training, data and resource management. <h2>The need for resilience</h2> Perhaps the key lesson for New Zealand, and also Australia, is the need to think beyond emergency management to building long-term resilience within agencies and communities. As climate-related disasters become more common, we need to think about how our cities grow and how we can incorporate flood resilience by retaining green areas and vegetation, improved drainage and transportation links. But both countries also need to focus on being ready for a disaster, instead of managing it after it happens. In doing so, the pressures of managing the disaster when it arrives would be less – and so would the long-term impacts on people and the economy.

“Fun until it wasn’t”: Grant Denyer takes smiling selfie moments before disaster

Former Sunrise presenter Grant Denyer has taken to Instagram to report that he was involved in a disastrous biking accident. Grant, who has been training ahead of the 2023 Bathurst 12 Hour race this weekend, was with friend and training partner Mick when they ran into trouble. Despite dubbing the incident a “huge stack”, it seems no real injury was sustained, with Denyer’s sharing a light hearted take with his 408k followers. “No joke, 2 mins after this photo we had a huge stack doing wheelies and clipping handlebars,” he captioned the image. The photo in question features Grant and Mick on their bikes, cycling along a country road, with big smiles on each of their faces. “D*ckheads,” Grant said of the pair, and added that they were “putting in the big yards for the @bathurst12hr this weekend.

"This is crazy": Ellen shares worrying update from storm-lashed LA

Former talk show host Ellen DeGeneres shared an update on Twitter showing the intensity of the wild storms hitting Los Angeles. The 64-year-old gave an up close and personal look at how the storm was wreaking havoc near her Montecito mansion. "Montecito is under mandatory evacuation. We are on higher ground so they asked us to shelter in place. Please stay safe everyone," she wrote. The video shows DeGeneres bundled up in a grey raincoat and hoodie as the rising floodwaters in the creek raged behind her. "This creek next to our house never flows, ever. It’s probably about nine feet [2.7m] up. It could go another two feet [60cm] up. We have horses ready to evacuate," she said. DeGeneres lives in an affluent area with other A-listers including the Duke and Duchess of Sussex, Oprah Winfrey, Katy Perry and Orlando Bloom. <blockquote class="twitter-tweet"> Montecito is under mandatory evacuation.

Why The Block 2023 is looking at a potential disaster

The Block's producers and contestants may suffer financially in what could be the "worst series yet" in 2023, given the current economic climate, according to experts. However, there is one saving grace for the next instalment of the Channel 9 reality series and that is the new location that’s been selected. The hugely successful series sees five couples renovate a property each before selling it at auction, with contestants able to keep any profit above a set reserve. In 2023 they'll be up against a different property market compared to the heated conditions enjoyed by fans of the show in previous series. After staging a "tree change" season in Gisborne, located in Victoria's Macedon Ranges this year, The Block will return to Melbourne's Bayside in 2023 – the location having already been leaked. Producers bought five classic brick homes in Hampton East at 14 Charming Street, 16 Charming Street, 18 Charming Street, 20 Charming Street, and 22 Charming Street, securing them all at once, costing $14.3 million. The humble Charming Street blocks, which measure around 600sqm to 700sqm, will this time next year be occupied by high-end trophy homes, with the show's producers and contestants hoping to net big profits. "The Block has paid a premium there, double what we would expect the properties to be worth. It could be financially the worst series yet. "They're $7 million behind the eight-ball from day dot." The median house price in Hampton East is $1.55 million, down from a price peak of $1.57 million in February, with a further drop in price expected. Nationally, home prices have slipped 3.53% since March. To be able to recoup their money in 2023, producers will have to do some good advertising and sponsorship deals, he added. Local real estate agents remain skeptical that the renovated properties will be able to sell and turn a profit. Nevertheless, Mr Sibley, director of Buxton Hampton East remains optimistic The Block can set a new suburb benchmark and current property owners could benefit. Mr Valentic said while it was "hard" to get buyers willing to pay $4 million on a property in Gisborne, it shouldn't be as hard to find those willing to spend $3 million in Melbourne's Bayside. The question is whether that price will be good enough for producers and contestants. Images: Channel 9

Thousands of dollars now available for flood victims

The victims of recent flooding events in Victoria, New South Wales and Tasmania are now eligible for financial support from the federal government. Thousands of dollars in support will include ongoing payments for eligible Aussies who have lost income as a result of the floods, paid at the same rate as JobSeeker. “The disaster recovery allowance is a payment that’s currently being made across all 71 LGAs (local government areas) ... for a total of up to 13 weeks,” Services Australia General Manager Hank Jongen told Sunrise. “It’s to help people that have lost work or income as a direct result of the floods, regardless of whether you’re an employer, sole trader or an employee.” <blockquote class="twitter-tweet"> Financial support is now available for people affected by flooding in New South Wales, Victoria and Tasmania.

But, fewer Local Government Areas (LGAs) qualify for the lump sum along with the allowance, with eligible LGAs being determined by the National Emergency Management Agency. “This is an ever-changing situation and the National Emergency Management Agency is constantly monitoring, and it works with other government agencies in order to make these declarations,” Mr Jongen explained.

Floods in Victoria are uncommon. Here’s why they’re happening now – and how they compare to the past

Think Victoria and disasters and you’ll think bushfires. But floods can hit – just not as often. Today is one of those days, with much of the state under a flood watch. Premier Dan Andrews says the floods are likely to be the <a href="https://www.abc.net.au/news/2022-10-13/nsw-victoria-tasmania-wet-weather-flooding-rainfall-live-updates/101530310?utm_campaign=abc_news_web&utm_content=twitter&utm_medium=content_shared&utm_source=abc_news_web" target="_blank" rel="noopener">most significant</a> in years. Evacuations are likely. Floodwaters are pushing down the Goulburn to the Murray. Major flooding in the Maribyrnong, which runs through towns and Melbourne’s west. Emergency services say evacuations may be necessary. Towns are sandbagging flood-prone areas. Some have been cut off by rising waters. The state’s largest dam, Dartmouth, is spilling over. So is Lake Eildon’s dam. And the Thomson dam may well spill this weekend, for the first time in decades. This isn’t the last of it – Victoria’s emergency management commissioner Andrew Crisp has warned intense rains and floods could last up to <a href="https://www.3aw.com.au/in-this-for-a-while-emergency-management-commissioners-warning-to-victorians/" target="_blank" rel="noopener">six to eight weeks</a>. Even as the rest of the eastern seaboard has faced the brunt of three consecutive La Niña years, Victoria has had little flooding until now. Tasmania, too, is facing rare flooding, while flood-weary New South Wales is bracing for more. These heavy rains are unusual. Dense cloud bands have crossed the desert, carrying moisture evaporating from seas off north-west Australia. Rain has fallen across almost the entire continent in the last two weeks. Our rain events are usually regional – <a href="https://theconversation.com/on-our-wettest-days-stormclouds-can-dump-30-trillion-litres-of-water-across-australia-191949" target="_blank" rel="noopener">not national</a>. <h2>Why doesn’t Victoria have as many floods?</h2> Victoria’s claim to fame in disasters is that it’s the most <a href="https://insidestory.org.au/we-have-still-not-lived-long-enough/" target="_blank" rel="noopener">bushfire-prone region</a> in the world (followed by California and Greece). Fire risk also comes from climate. Victoria’s temperate climate means dry summers and less rain than its northern counterparts – around 520 millimetres of rain a year falls on average in Melbourne, compared to 1175mm a year in Sydney and 1149mm in Brisbane. Up north, rain tends to fall intensely, whereas Victoria’s rain tends to fall more as drizzle. What’s different this time? September was wetter and colder <a href="http://www.bom.gov.au/climate/current/month/vic/summary.shtml" target="_blank" rel="noopener">than usual</a> in Victoria, which meant the ground was already saturated in many areas. Colder weather means less water evaporates. Together, that made the state primed for floods. For a flood to happen, you need a high rate of run-off, where rain hits saturated soils and flows overland rather than sinking in, as well as intense rains in a short period. Victoria is more familiar with flash floods. That’s because the stormwater drains in cities and towns can be overwhelmed by sudden dumps of rain, flooding streets. The good news is this flooding is usually over quickly, in contrast to the flooded rivers we see up north. This situation may be different. With the state’s major dams beyond capacity or very close to it, water is already spilling over. Dams in Australia are often dual-purpose, storing drinking water and allowing us some control over floods. While Brisbane’s dams are designed with gates to permit floodwater release, Victoria’s dams tend to just have dam walls. When dams overflow, they can add to floods in low-lying areas downstream. There’s also usually a lag time in riverine floods, as it takes hours or sometimes days for rain falling in the headwaters to end up as floodwater downstream. <h2>What floods has Victoria seen before?</h2> The largest was in 1934. More than 140mm of rain fell over two days in Melbourne, and more than double that in Gippsland. The <a href="https://trove.nla.gov.au/newspaper/article/10998182" target="_blank" rel="noopener">enormous flood</a> that followed was most devastating in Melbourne, where the Yarra <a href="https://knowledge.aidr.org.au/resources/flood-melbourne-and-victoria-1934/" target="_blank" rel="noopener">broke its banks</a> and formed a lake from the city out to the outer suburbs. Thirty-six people died, and thousands of people were left homeless. Floods in the capital and in the regions are <a href="https://www.theage.com.au/national/victoria/a-brief-history-of-victorian-floods-20171202-gzxcem.html" target="_blank" rel="noopener">rare but not unknown</a>. In 1891, floods forced more than 3,000 people from their homes in Richmond, Collingwood and Prahran. In 1909, western Victorian rivers broke their banks, flooding many towns and causing four deaths. The <a href="https://www.floodvictoria.vic.gov.au/learn-about-flooding/flood-history/post-2000-floods" target="_blank" rel="noopener">most recent</a> big floods took place during the previous La Niña cycle from 2010-2012, with western Victoria taking the brunt of the damage. Flooding in Victoria has also reduced because people have shifted the course of rivers – particularly the Yarra. In 1879, 2,000 workers began a monster task: removing an entire loop of the Yarra west of the Docklands. One reason? Straight rivers flow faster, meaning floodwaters can discharge more quickly. Engineer John Coode was responsible for designing the new course for the Yarra, which also had the benefit of a wide new channel to improve access for ships. In the process, his workers created what’s now known as Coode Island. In 1896, Victoria’s Parliament passed the <a href="http://classic.austlii.edu.au/au/legis/vic/hist_act/yia1896218/" target="_blank" rel="noopener">Yarra Improvement Act</a> in a bid to reduce the damage caused by floods. Workers widened and deepened the river, and removed billabongs near the Botanic Gardens in the process. In the 1930s, engineers built another channel through an old quarry leading to the creation of Herring Island. These changes were mainly about improving navigation for ships – but they had the double benefit of reducing flooding in the lower reaches. In part, it was about British ideals of what rivers should look like, using highly modified rivers like London’s Thames as a guide. <h2>What’s next?</h2> Changing the course of rivers, raising dams and building levees can make us feel like we’re in control. Unfortunately, it’s not that simple, as <a href="https://theconversation.com/its-time-to-come-clean-on-lismores-future-people-and-businesses-have-to-relocate-away-from-the-floodplains-184636" target="_blank" rel="noopener">Lismore’s residents found</a>. Flood control measures can actually make the impact of <a href="https://theconversation.com/to-stop-risky-developments-in-floodplains-we-have-to-tackle-the-profit-motive-and-our-false-sense-of-security-184062" target="_blank" rel="noopener">large floods worse</a> by giving us a false sense of security about living on floodplains. This is unlikely to be the last flood before La Niña finally relents. It’s worth knowing your state’s history of disasters – so you can be better prepared. After all, we can’t control nature.

‘Patently ridiculous’: State government failures have exacerbated Sydney’s flood disaster

For the fourth time in 18 months, floodwaters have inundated homes and businesses in Western Sydney’s Hawkesbury-Nepean Valley. Recent torrential rain is obviously the immediate cause. But poor decisions by successive New South Wales governments have exacerbated the damage. The town of Windsor, in the Hawkesbury region, has suffered a particularly high toll, with dramatic flood heights of 9.3 metres in February 2020, 12.9m in March 2021 and 13.7m in March this year. As I write, flood heights at Windsor have reached nearly 14m. This is still considerably lower than the monster flood of 1867, which reached almost 20m. It’s clear that standard flood risk reduction measures, such as raising building floor levels, are not safe enough in this valley. We’ve known about the risk of floods to the region for a long time. Yet successive state governments have failed to properly mitigate its impact. Indeed, recent urban development policies by the current NSW government will multiply the risk. <blockquote class="twitter-tweet"> BBC weather putting Sydney’s downpour into context. More rain there in 4 days than London gets in a year. <a href="https://t.co/FDkBCYGlK7">pic.twitter.com/FDkBCYGlK7</a> — Brett Mcleod (@Brett_McLeod) <a href="https://twitter.com/Brett_McLeod/status/1544071890431623169?ref_src=twsrc%5Etfw">July 4, 2022</a></blockquote> We knew this was coming A 22,000 square kilometre catchment covering the Blue Mountains and Western Sydney drains into the Hawkesbury-Nepean river system. The system faces an <a href="https://theconversation.com/sydneys-disastrous-flood-wasnt-unprecedented-were-about-to-enter-a-50-year-period-of-frequent-major-floods-158427" target="_blank" rel="noopener">extreme flood risk</a> because gorges restrict the river’s seaward flow, often causing water to rapidly fill up the valley after heavy rain. Governments have known about the flood risks in the valley for more than two centuries. Traditional Owners have known about them for millennia. In 1817, Governor Macquarie lamented: <blockquote> it is impossible not to feel extremely displeased and Indignant at [colonists] Infatuated Obstinacy in persisting to Continue to reside with their Families, Flocks, Herds, and Grain on those Spots Subject to the Floods, and from whence they have often had their prosperity swept away. </blockquote> Macquarie’s was the first in a long line of governments to do nothing effective to reduce the risk. The latest in this undistinguished chain is the NSW Planning Minister Anthony Roberts. In March, Roberts <a href="https://www.smh.com.au/national/nsw/nsw-planning-minister-scraps-order-to-consider-flood-fire-risks-before-building-20220321-p5a6kc.html" target="_blank" rel="noopener">reportedly revoked</a> his predecessor’s directive to better consider flood and other climate risks in planning decisions, to instead favour housing development. Roberts’ predecessor, Rob Stokes, had required that the Department of Planning, local governments and developers consult Traditional Owners, manage risks from climate change, and make information public on the risks of natural disasters. This could have helped limit development on floodplains. <blockquote class="twitter-tweet"> Michael Greenway knows that as soon as he sees floodwater, it’s time to get the three boxes of family photos and move to higher ground. He’s lived in his Richards home for years and has experienced six floods - three of which have been this year <a href="https://t.co/t8Tgckc5lx">https://t.co/t8Tgckc5lx</a> <a href="https://twitter.com/hashtag/NSWFloods?src=hash&ref_src=twsrc%5Etfw">#NSWFloods</a> <a href="https://t.co/ErN6sf6hBn">pic.twitter.com/ErN6sf6hBn</a> — Laura Chung (@Laura_R_Chung) <a href="https://twitter.com/Laura_R_Chung/status/1543890156675276800?ref_src=twsrc%5Etfw">July 4, 2022</a></blockquote> Why are we still building there? The Hawkesbury-Nepean Valley is currently home to 134,000 people, a population <a href="https://www.infrastructure.nsw.gov.au/expert-advice/hawkesbury-nepean-flood-risk-management-strategy/" target="_blank" rel="noopener">projected to</a> double by 2050. The potential <a href="https://theconversation.com/to-stop-risky-developments-in-floodplains-we-have-to-tackle-the-profit-motive-and-our-false-sense-of-security-184062?utm_source=twitter&utm_medium=bylinetwitterbutton" target="_blank" rel="noopener">economic returns</a> from property development are a key driver of the <a href="http://www.jstor.org/stable/26393302" target="_blank" rel="noopener">lack of effective action</a> to reduce flood risk. In the valley, for example, billionaire Kerry Stokes’ company Seven Group is <a href="https://www.smh.com.au/national/how-raising-the-warragamba-dam-wall-could-be-a-win-for-billionaire-kerry-stokes-20220222-p59yke.html" target="_blank" rel="noopener">reportedly a part owner</a> of almost 2,000 hectares at Penrith Lakes by the Nepean River, where a 5,000-home development has been mooted. Planning in Australia often uses the 1-in-100-year flood return interval as a safety standard. <a href="https://nccarf.edu.au/living-floods-key-lessons-australia-and-abroad/" target="_blank" rel="noopener">This is not appropriate</a>. Flood risk in the valley is increasing with climate change, and development in the catchment increases the speed of runoff from paved surfaces. The historical 1-in-100 year safety standard is particularly inappropriate in the valley, because of the extreme risk of rising water cutting off low-lying roads and completely submerging residents cut-off in extreme floods. What’s more, a “medium” climate change scenario will see a <a href="https://www.infrastructure.nsw.gov.au/expert-advice/hawkesbury-nepean-flood-risk-management-strategy/resources/publications-and-resources/" target="_blank" rel="noopener">14.6% increase</a> in rainfall by 2090 west of Sydney. This is projected to increase the 1-in-100 year flood height at Windsor from 17.3m to 18.4m. The NSW government should impose a much higher standard of flood safety before approving new residential development. In my view, it would be prudent to only allow development that could withstand the 20m height of the 1867 flood. No dam can control the biggest floods The NSW government’s primary proposal to reduce flood risk is to <a href="https://www.infrastructure.nsw.gov.au/expert-advice/hawkesbury-nepean-flood-risk-management-strategy/" target="_blank" rel="noopener">raise Warragamba Dam</a> by 14m. There are many reasons this <a href="https://www.giveadam.org.au/" target="_blank" rel="noopener">proposal should be questioned</a>. They include the potential inundation not just of <a href="https://www.smh.com.au/national/traditional-owners-launch-federal-bid-to-stop-raising-of-warragamba-dam-wall-20210128-p56xkt.html" target="_blank" rel="noopener">cultural sites</a> of the Gundungarra nation, but threatened species populations, and part of the Blue Mountains World Heritage Area. The <a href="https://www.infrastructure.nsw.gov.au/media/2855/infrastructure-nsw-resilient-valley-resilient-communities-2017-jan.pdf" target="_blank" rel="noopener">cost-benefit analysis</a> used to justify the proposal <a href="https://www.parliament.nsw.gov.au/committees/inquiries/Pages/inquiry-submission-details.aspx?pk=65507" target="_blank" rel="noopener">did not count</a> these costs, nor the benefits of alternative measures such as upgrading escape roads. Perversely, flood control dams and levee banks often result in higher flood risks. That’s because none of these structures stop the biggest floods, and they provide an illusion of safety that justifies more risky floodplain development. The current NSW transport minister <a href="https://www.smh.com.au/national/nsw/emergency-minister-says-raising-dam-wall-could-lead-to-more-development-on-floodplain-20210329-p57evo.html" target="_blank" rel="noopener">suggested such development</a> in the valley last year. Similar development occurred with the construction of the Wivenhoe Dam in 1984, which hasn’t prevented extensive flooding in <a href="http://www.jstor.org/stable/26393302" target="_blank" rel="noopener">Brisbane</a> in 2011 and 2022. These are among the reasons the NSW Parliament Select Committee on the Proposal to Raise the Warragamba Dam Wall <a href="https://www.parliament.nsw.gov.au/committees/listofcommittees/Pages/committee-details.aspx?pk=262#tab-reportsandgovernmentresponses" target="_blank" rel="noopener">recommended</a> last October that the state government: <blockquote> not proceed with the Warragamba Dam wall raising project [and] pursue alternative floodplain management strategies instead. </blockquote> What the government should do instead The NSW government now has an opportunity to overcome two centuries of failed governance. It could take substantial measures to keep homes off the floodplain and out of harm’s way. We need major <a href="https://www.parliament.nsw.gov.au/committees/inquiries/Pages/inquiry-submission-details.aspx?pk=65507" target="_blank" rel="noopener">new measures</a> including: <ul> <li>preventing new development</li> <li>relocating flood prone residents</li> <li>building better evacuation roads</li> <li>lowering the water storage level behind Warragamba Dam.</li> </ul> The NSW government should help residents to relocate from the most flood-prone places and restore floodplains. This has been undertaken for many Australian towns and cities, such as <a href="https://www.sciencedirect.com/science/article/pii/S2212420914000028" target="_blank" rel="noopener">Grantham</a>, Brisbane, and <a href="https://nccarf.edu.au/living-floods-key-lessons-australia-and-abroad" target="_blank" rel="noopener">along major rivers worldwide</a>. <a href="https://www.mdpi.com/2073-4441/5/4/1580/htm#B10-water-05-01580" target="_blank" rel="noopener">Relocating residents isn’t easy</a>, and any current Australian buyback and relocation programs are voluntary. I think it’s in the public interest to go further and, for example, compulsorily acquire or relocate those with destroyed homes, rather than allowing them to rebuild in harm’s way. This approach offers certainty for flood-hit people and lowers community impacts in the longer term. It is patently ridiculous to rebuild on sites that have been flooded multiple times in two years. In the case of the Hawkesbury-Nepean Valley, there are at least <a href="https://www.theaustralian.com.au/nation/politics/federal-government-insurers-stop-housing-in-floodrisk-zones/news-story/cba71269eff2b0ea00d93445ff0e9f73" target="_blank" rel="noopener">5,000 homes</a> below the 1-in-100-year flood return interval. This includes roughly <a href="https://www.hawkesburygazette.com.au/story/7657492/near-1000-flood-related-home-insurance-claims-already-in-hawkesbury/" target="_blank" rel="noopener">1,000 homes flooded</a> in March. The NSW government says a buyback program would be <a href="https://www.smh.com.au/politics/nsw/farcical-minister-shoots-down-flood-relocation-says-residents-know-the-risks-20220308-p5a2qg.html" target="_blank" rel="noopener">too expensive</a>. Yet, the cost would be comparable to the roughly $2 billion needed to raise Warragamba Dam, or the government’s $5 billion WestInvest fund. An alternative measure to raising the dam is to lower the water storage level in Warragamba Dam by 12m. This would reduce the amount of drinking water stored to supply Sydney, and would provide some flood control space. The city’s water supply would then need to rely more on the existing desalination plant, a <a href="http://www.sciencedirect.com/science/article/pii/S1364032116001817" target="_blank" rel="noopener">strategy assessed as cost effective</a> and with the added benefit of bolstering drought resilience. The flood damage seen in NSW this week was entirely predictable. Measures that could significantly lower flood risk are expensive and politically hard. But as flood risks worsen with climate change, they’re well worth it.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/186304/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/jamie-pittock-7562" target="_blank" rel="noopener">Jamie Pittock</a>, Professor, Fenner School of Environment & Society, <a href="https://theconversation.com/institutions/australian-national-university-877" target="_blank" rel="noopener">Australian National University</a> This article is republished from <a href="https://theconversation.com" target="_blank" rel="noopener">The Conversation</a> under a Creative Commons license.

Natural disaster declared for NSW

The Australian Government has declared a natural disaster for parts of New South Wales. Torrential rain has continued to batter the state as tens of thousands of residents have evacuated flood prone areas, others have been left stranded waiting to be rescued by the SES, and 21 people are stuck in a cargo ship following an engine failure. The SES said there were 5,300 calls for help, 252 people were rescued overnight and a further 45,000 people have been forced to flee their homes. Despite the rain expecting to ease today, SES Assistant Commissioner Sean Kearns there’s concern for certain areas. "Our biggest concern today is ongoing riverine flooding along the Hawkesbury, Nepean and the Georges rivers, with our focus areas being McGraths Hill, Pitt Town, Woronora, Liverpool and Milperra," he said. A natural disaster has been declared in 23 Local Government Areas which have been left submerged by rising waters. The residents in the 23 LGAs affected by the severe storms and flooding since June 27, will now be eligible for disaster relief payments funded by the NSW government and the Commonwealth. The LGAs include Blacktown, Blue Mountains, Camden, Canterbury Bankstown, Campbelltown, Central Coast, Cessnock, Fairfield, Georges River, Hawkesbury, Hornsby, Kiama, Lithgow, Liverpool, Northern Beaches, Penrith, Shellharbour, Shoalhaven, Sutherland, The Hills, Wingecarribee, Wollondilly and Wollongong. “We have seen some of these impacted communities being hit by floods for a third and fourth time in 18 months, which is extremely distressing to the residents of these communities,” Minister for Emergency Management, Senator Watt said. “The Australian and New South Wales governments have worked very cooperatively through this latest flood emergency, to ensure defence and other resources were deployed early and fast. “Similarly, we’re now working hard together to make sure that impacted communities get the financial and other assistance they need as soon as possible.” It comes as a delicate rescue operation continues for bulk carrier ship Portland Bay after it lost power on Monday leaving 21 crew members stranded. The ship then began drifting towards the coast of the Royal National Park, south of Sydney but the crew managed to drop two anchors in the wild 5.5m swells. John Finch, chief operating officer at Port Authority, said the main objective was to move the ship to deeper waters. "The priority is getting this vessel and its crew into safer waters and away from land and the potential of grounding," he said. "All tugs have now arrived and connected to the ship so the operation has commenced to raise its anchors and move this ship safely out to sea in a slow and controlled manner. "The conditions make the towage operation quite difficult. In eight-metre swell, the vessel is going to be rising and falling and rolling. That's going to put a lot of stress on the equipment and the tug lines." The port authority has managed to move the ship about 20 nautical miles offshore and out of immediate danger.

9 tips for keeping your pet safe during a natural disaster

1. Be prepared for the worst Embrace the Boy Scout motto: Always be prepared. You don’t want to find yourself in the middle of an emergency and not have the tools you, your family, and your pets need to survive. Russell Hartstein, acclaimed dog and cat behaviourist, trainer and nutritionist, says that the most common mistake people make during a natural disaster is leaving pets behind. “You can’t leave a dog or cat at home thinking they will be OK with a bunch of food and water. They won’t be OK, and they will likely die,” he warns. 2. Keep extra food on hand Always have enough food on hand to last your pet for at least two weeks, recommends Hartstein. Keep plenty of treats handy as well, he says. These can help your pet stay calm and happy. The treats will also be useful for getting your pet to behave during this stressful time. Lastly, buy a few collapsible bowls for your pet to eat and drink out of; they’re easier to transport and take up less space. 3. Grab comfort toys or blanket Hartstein emphasises that it’s essential to have “special toys or comfort items to relieve boredom and reduce stress.” Whether your pet has a favourite toy, blanket, or just loves bones, it would be helpful to have their comfort items on hand to help them relax. Going through a natural disaster and heading to an unknown destination is scary for your pet; these familiar items will put them at ease. 4. Invest in pet first-aid kit While you no doubt have a first-aid kit for family emergencies, you may not have one for your furry friends. You don’t have to be a veterinarian to help your wounded animal. Hartstein recommends you look for one that can handle paw care, small cuts, wound dressing, hydrogen peroxide, tweezers, scissors, gauze pads and rolls, adhesive tape. Consider adding hand sanitiser, a muzzle, paper towels, sheets, bowls, toys and peanut butter or any food that really motivates your pet to help deal with an actual procedure, he says 5. Keep vaccination and prescription records with passport Keep all of your pet’s medical records in a folder next to your important papers so that they’ll be easy to grab when you’re heading out the door. If your dog is on prescription medications, take proof of that with you in case you need to visit a pharmacy on the road. You should also have proof that your dog is licensed and up to date on vaccinations. And keep an up-to-date photo: “Bring current photos of your pets and descriptions,” says Hartstein. Write down the detailed markings of your pets, he says, so you can find them if you become separated. 6. Consider protective pet wear A life vest or anything else that would help keep them afloat in a flash flood is also important. A tight-fitting anxiety vest can be consoling for pets who are prone to anxiety. Hartstein adds, “Consider purchasing dog boots to protect your dog’s paws from the elements.” Rough surfaces and debris can cause injury, as can hot summer roads. 7. Clean water During a state of emergency, experts recommend you boil your water for at least one minute (three, if you’re above 1,500m elevation) to make it potable before drinking it – and before giving it to your pets. (Don’t forget to let it cool first!) As an alternative, Hartstein says, you can purchase water purifying tablets, filters like the LifeStraw, or a UV device. These methods are simple and can prevent illness in both you and your pet. 8. Get a ramp for bigger dogs Small dogs, cats and other pets will be easy to carry out of trouble. Large dogs – especially elderly ones – can be more of a challenge, Hartstein says: “If you are not strong enough to lift your dog, or if your dog is too old to lift without injuring them, think about a ramp to walk them into your truck or car.” 9. Practice with your pets A disaster will be much less stressful if you and your pets are ready to handle severe situations. Try going through your evacuation drill with your pet by collecting the first-aid kit, comfort items, and getting the animal into the carrier or car. Make it fun, Hartstein explains: “Condition your dog and cat to love all of the items and process of evacuation. Most importantly, expose them positively to new stimuli and environments gradually, only with positive reinforcement. Have them looking forward to road trips and different or unfamiliar sounds, smells, surfaces and sights.”

Readers respond: What is your biggest screw-up in the kitchen?

We asked our readers what their biggest disaster in the kitchen was, and it turns out not everyone can be a culinary expert! From microwave explosions to inedible ingredients, here's just a few of your biggest cooking mishaps. Scolie Simpson - Years ago a lady and I were talking about our first microwave disasters and and she told me that when they got theirs she need to do quite a few boiled eggs for some party thing .So she put either a dozen or 2 in the microwave and went to watch TV. All of a sudden they heard an almighty bang and when she looked the door had blown off and there was egg in every part of the kitchen. The friend next door couldn't stop laughing and said that she should have pierced each egg. She went back to just boiling them. Pamela Crowe - First married, home from work, put oil in pot, turned on hot plate, forgot to buy mince. Went to butchers. Got back to flat, apparently the oil exploded - black ash over every surface. Gay Sharran Gold - I decided to whip up egg whites for a pavlova. I had put the beaters in the mixmaster in reverse unknowingly! I turned it on full throttle and stood there within seconds with egg white through my hair, in my eyes and down my face, sticking to the curtains, dripping down the window and all over the cupboards and floor!! Heather Widjaja - Put chicken bones on the stove to make stock. Forgot to turn the burner off and went out for six hours!!!! Came home to a house full of smoke, disgusting smell and luckily just a ruined saucepan, but a house still standing. Maureen Ivan Notsch - Cooked a chook with the plastic bag with giblets still inside it. Roula May - Sprayed chicken Kiev with fly spray instead of oil! Chook Milne - Used Mr Sheen instead of canola spray on my cake tin.. lucky everyone survived. Vicki Newbury - Made tuna patties and used what I thought was plain flour to roll them in, turned out it was actually custard powder, didn’t realise until they were cooking in the pan, needless to say the whole lot went into the bin. Dawn Croft - When microwaves were brand new I reheated a tuna pasta. It was great. I commented that everyone said that you couldn't get crispy topping in the microwave but my cheese was great. Didn't realise till I went to wash up my Tupperware container that my crispy topping was the plastic from my Tupperware. I survived! Sue Anderson - Made gravy with drinking chocolate instead of Gravox… thought it looked a bit funny so added Parisian Essence. First bite of the roast was a bit exciting for all. Kaye Brown - Making toffee. Everything including the pot was thrown out, after we’d convinced the neighbours and the fire brigade all was fine. Cheryl Millard - Melting chocolate In the microwave. Not knowing that the chocolate doesn’t lose its shape so kept zapping . No bottom left in bowl but chocolate still in its squares. Michael L Carrigg - Entering the kitchen, told to stay out as a youngster and has kept me in good stead ever since, except to make coffee. Gail Fredericks - Forgot to put yeast in the bread maker. Ended up with a very nice brick. Image credits: Getty Images

‘One of the most extreme disasters in colonial Australian history’

The deluge dumped on southeast Queensland and northern New South Wales this week has been catastrophic. Floodwaters peaked at around 14.4 metres high in Lismore – two metres higher than the city’s previous record. So how does this compare to Australia’s previous floods, such as in 2011? And can we expect more frequent floods at this scale under climate change? The answers to questions like these aren’t straightforward. Climate change doesn’t tell the whole story, as extreme rainfall can occur for a <a href="https://theconversation.com/like-rivers-in-the-sky-the-weather-system-bringing-floods-to-queensland-will-become-more-likely-under-climate-change-176711">variety of reasons</a>. What’s more, it’s too soon to officially state whether this event is directly linked to climate change, as this would require a formal event attribution study. This can take months or years to produce. In any case, we do know extreme events like this will occur more frequently in a warmer world. And the rising death toll, ongoing evacuations and destroyed homes make this one of the most extreme natural disasters in colonial Australian history. How this compares to floods in our past The east coast is a common place for heavy rainfall and flooding. The Yugara and Yugarabul people have <a href="https://www.oxleycreekcatchment.org.au/history/">traditional stories about great floods</a> in the Brisbane river region long before European colonisation, and sediments from floodplains indicate floods as severe as those in 2010–2011 have occurred <a href="https://theconversation.com/old-floods-show-brisbanes-next-big-wet-might-be-closer-than-we-think-70392">at least seven times in the past 1,000 years</a>. Instrumental records and <a href="https://www.slq.qld.gov.au/blog/overview-brisbane-river-floods">documentary accounts</a> show severe floods have inundated southern Queensland’s cities and towns in the 1820s, early 1840s and 1890s, 1931, 1974 and, of course, in 2010–2011. Each of these events have been devastating, and record-breaking, depending on which records you’re interested in. The floods in 1841 and 1893 are considered highest in terms of <a href="https://www.abc.net.au/news/2021-01-16/brisbane-flood-history-should-not-take-people-by-surprise/13051826">water levels recorded in Brisbane city</a>, reaching over 8m. Australia’s wettest day on record was also recorded in 1893, when Crohamhurst in the Glasshouse Mountains measured 907 millimetres in one day. <figure class="align-center "><img src="https://images.theconversation.com/files/449172/original/file-20220301-4202-1lwf5fm.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/449172/original/file-20220301-4202-1lwf5fm.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=402&fit=crop&dpr=1 600w, https://images.theconversation.com/files/449172/original/file-20220301-4202-1lwf5fm.jpeg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=402&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/449172/original/file-20220301-4202-1lwf5fm.jpeg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=402&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/449172/original/file-20220301-4202-1lwf5fm.jpeg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=505&fit=crop&dpr=1 754w, https://images.theconversation.com/files/449172/original/file-20220301-4202-1lwf5fm.jpeg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=505&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/449172/original/file-20220301-4202-1lwf5fm.jpeg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=505&fit=crop&dpr=3 2262w" alt="Black and white image of men in a small boat in front of a tall brick building that is half submerged in flood water.

The Brewery building was damaged even further in the 1893 flood, when the Brisbane River rose 10 feet above the 1890 record. John Oxley Library, State Library of Queensland</figcaption></figure> The 1974 event was associated with extreme rainfall totals in many coastal areas, including 314mm in one day in Brisbane, and more than a metre of rainfall was recorded over three days in places such as Mount Tamborine and the northwest of Surfers Paradise. The 2010–11 flood, while not as severe in terms of extreme rainfall totals, <a href="http://www.bom.gov.au/climate/current/statements/scs24b.pdf">was notable for its inland extent</a>, and was the final act of Australia’s wettest July to December on record. The current flood has peaked at 3.85m in Brisbane, below the 2010–2011 levels of 4.46m. But it’s breaking records in other areas such as Lismore in northern NSW. The rainfall statistics associated with this event are also nearing the highest on record for many places, possibly due to the slow-moving nature of the associated weather system. Four of the top six highest rainfall totals in NSW were <a href="https://www.weatherzone.com.au/news/second-heaviest-daily-rainfall-ever-observed-in-nsw/536322">recorded on 28 February</a>, and Brisbane has just experienced three days of over 200mm. These aren’t the highest daily totals ever recorded in the city, but the first time three days of such intense falls have been documented, in data that go back to 1841. Disentangling the role of climate change When it comes to understanding the role of human-induced climate change in extreme events, there is the temptation to ask the wrong question: “did climate change cause this event?” Since any extreme event is always a manifestation of climate variability, large weather systems, local-scale weather and climate change, it’s impossible to categorically answer this question with a simple “yes” or “no”. Instead, the question we should be asking is “did climate change contribute to this event?” Well, firstly, there has actually been a slight decrease in summer rainfall in southeast Queensland and northeast NSW since the mid-20th century. But, there’s very high variability in rainfall for this region, and La Niña – a natural climate phenonenon associated with wetter weather – often brings flooding to this area, as we saw in 2010/2011 and in the 1970s. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/449171/original/file-20220301-15-1h65whn.png?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/449171/original/file-20220301-15-1h65whn.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/449171/original/file-20220301-15-1h65whn.png?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=424&fit=crop&dpr=1 600w, https://images.theconversation.com/files/449171/original/file-20220301-15-1h65whn.png?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=424&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/449171/original/file-20220301-15-1h65whn.png?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=424&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/449171/original/file-20220301-15-1h65whn.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=533&fit=crop&dpr=1 754w, https://images.theconversation.com/files/449171/original/file-20220301-15-1h65whn.png?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=533&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/449171/original/file-20220301-15-1h65whn.png?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=533&fit=crop&dpr=3 2262w" alt="" /></a><figcaption>Trends in maximum 3-day rainfall in summer (December-February) from 1959/1960 to 2019/2020 show mixed trends in the flood-affected region.

Author provided</figcaption></figure> Indeed, the effect of La Niña (and its counterpart El Niño, associated with drier weather) makes identifying a climate change-related trend more difficult. In other words, while a human-induced climate change signal may be present, the naturally high variability makes it hard to spot. The atmosphere can hold approximately 7% more moisture for every degree Celsius of global warming. However, we also need the right weather systems in place to trigger the release of moisture from the air and cause extreme rainfall. The climate change effect on these systems is uncertain. Climate change and weather systems The severity of the flooding in southeast Queensland is partly due to a weather system called an “<a href="https://theconversation.com/like-rivers-in-the-sky-the-weather-system-bringing-floods-to-queensland-will-become-more-likely-under-climate-change-176711">atmospheric river</a>” sitting over the region for days. To make matters worse, the rain fell on an already sodden ground due to both the higher-than-average rainfall from the current La Niña, and the La Niña in the 2020-2021 summer. This made a huge difference to the scale of the floods. We don’t fully understand how the persistence of these natural systems will change in future, but recent work shows climate change will cause long-lasting atmospheric rivers over Sydney to occur <a href="https://agupubs.onlinelibrary.wiley.com/doi/abs/10.1029/2021GL095335">almost twice as often</a> by the end of the 21st century. We don’t know yet if that’s also true further north of Sydney. To complicate things further, there’s <a href="https://www.carbonbrief.org/expect-twice-as-many-extreme-la-nina-events-under-climate-change-study-warns">evidence</a> to suggest climate change may be influencing the frequency, intensity and impacts of El Niño and La Niña events. <a href="https://interactive-atlas.ipcc.ch/regional-information#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">Climate change projections</a> also suggest we may see small increases in the number of extreme one-day rainfall events which typically lead to flash flooding, in eastern Australia. But there’s a lot of uncertainty. And worldwide, <a href="https://theconversation.com/mass-starvation-extinctions-disasters-the-new-ipcc-reports-grim-predictions-and-why-adaptation-efforts-are-falling-behind-176693">Monday’s report</a> from the Intergovernmental Panel on Climate Change projected that global warming of 2℃ this century will bring twice as much flood damage compared to 1.5℃ warming. This jumps to 3.9 times more flood damage at 3℃ warming. While the role of climate change is hard to pin down in Australia’s biggest floods, we know flooding often strikes our east coast. Building greater resilience to severe flooding would help lessen their impact.
