NSW Health Minister Brad Hazzard has confirmed that he is in isolation after coming into contact with a person who has tested positive for coronavirus.

“When I woke up this morning about 5.30 there was a text message from NSW Health advising me that there is a possible positive case who works at Parliament House in Sydney and that I should therefore self-isolate until further notice,” he told Sunrise on Thursday.

“They’re obviously doing some investigations, so I could be a close contact, I’m hoping I’m not, but we’ll see how the day transpires,” he added.

On Thursday morning, Minister for Agriculture and Western New South Wales, Adam Marshall confirmed to radio station 2GB that he is COVID positive but asymptomatic, and has “no doubt” it was from his visit to Christos pizza.

Marshall is one of four Nationals MPs who are currently in isolation after dining at the restaurant in inner Sydney.

The restaurant is a venue of concern according to NSW Health.

Only 16 MPs will be allowed in NSW Parliament on Thursday. The rest have been told not to come.

Hazzard has revealed the Premier was not affected.

“I would think that the Premier wouldn’t be a close contact, she’d be more likely to either not be a contact at all or be a casual contact,” he said.

“I can’t comment specifically on her because the message that I have received is about me, but if she had received such a message I think I’d have known about it by now.”

“So we’ve still got a Premier, we may not have a Health Minister who is at full capacity right now, but we still have a Premier,” he declared.

The news comes as Sydney deals with a growing outbreak.
