Hazzard said NSW is supporting the Victorian government push to change the definition of fully vaccinated in Australia from two doses to three.

But he says there are some issues to be ironed out before that change can be made. He doesn't know what issues, he says, because he is not a part of national cabinet.

I understand that most of these things require a range of medical expert input. In fact, they all require a range of medical expert input, and I think when you've got a committee of a large number of people, all giving their input, sometimes it takes a while to get there. Sometimes it is easier being a minister, I've got to say, than being on a committee.

So for everybody who is eligible, please go and get the booster as quickly as possible.
