Bindi Irwin has shared a heartfelt message for her husband, Chandler Powell, as he celebrated his 30th birthday.

The American-born wildlife conservationist marked the milestone on Saturday, with members of the Irwin family also sharing their tributes to Powell, who has taken on a major role at Australia Zoo.

“Grace and I both agree; you’re our world. And our home. We love you beyond description,” Bindi wrote.

The 27-year-old also added a little humour to the celebrations, joking about their two-year age difference.

“Today, we mourn the loss of a man in his 30s. He is survived by his younger, hotter wife,” read a card she gave him.

Bindi and Chandler first met in 2013 when he was visiting Australia for a wakeboarding competition. They began dating two years later, before Chandler migrated from the US to Australia in 2019.

The couple married in 2020 and welcomed their daughter, Grace Warrior, the following year.

Grace also had a special birthday message for her father, telling him in a video: “Happy birthday, Chandler. It’s me, Grace.”

She went on to describe her “Dada” as the “best man in the world”.

Bindi’s mother, Terri Irwin, shared her own tribute, reflecting on the many experiences they had shared since Chandler joined the family.

Terri said they had enjoyed “many adventures and stacks of fun” together, adding: “We are truly blessed to have you as part of our family.”

She also praised his role as a husband and father.

“You are a dedicated dad, endlessly kind to Bindi, and a true Wildlife Warrior. Looking forward to this next awesome decade.”

Bindi’s brother, Robert Irwin, also marked the occasion with several photos of himself and Chandler, including one showing the pair with baby Grace on a surfboard.

“The man, the myth, the legend has entered his third decade today. Happy birthday to the best of the best,” Robert wrote.
