Victoria has reported no new COVID-19 cases as Premier Daniel Andrews pushes for a dramatic reduction in Australians returning from overseas.
The Department of Health reported zero locally acquired cases on Thursday, following just over 29,000 tests, and also none in hotel quarantine.
Active cases in the state fell by three to 31, while more than 19,000 vaccine doses were administered at Victorian-run sites over the past 24-hour period.
It comes Mr Andrews said he would argue for a 50 to 80 per cent reduction in people coming back to Australia at national cabinet on Friday.
"We have it within our power to dramatically reduce the number of people who are coming back just for these next three or four months until we get a critical mass of people with a jab," he told reporters on Thursday.
He admitted the change would "difficult for some people who want to come home for the best of reasons".
"It won't be easy to lock some people out. But locking some people out is much better than locking everybody down," Mr Andrews said.
"That's my position and that's what I'll argue at national cabinet."
Mr Andrews said he could easily write to Prime Minister Scott Morrison to lower the state's current cap to 10, 15 or 20 per cent.
"I don't want to do that. I want it to be a national approach, and I want the rules to be as close to being the same in every state so that we're open."
Locked down Alice Springs, meanwhile, has become the latest local government area to be made a red zone from 11.59pm on Wednesday.
Anyone currently in Victoria who has been in Alice Springs at any time since June 25 will be required to get tested and stay isolated until they return a negative result.
Victorians can return home from red zones, but must self-isolate for 14 days.
Adelaide remains a green zone under Victoria's permit system for now, despite South Australia reporting five cases on Wednesday.
They are a miner who returned from the Northern Territory, his wife and three of their children.
