Experts are working over the weekend to analyse infection data from the first half of Victoria's six-week lockdown, but Victorian Premier Daniel Andrews admitted further restrictions could prove a "circuit breaker" for rising COVID-19 cases.
Australia's government expressed support on Sunday for the strictest social-distancing measures yet by the state of Victoria in an effort to contain the new coronavirus.
Students of parents who need to keep working will be allowed to go to school and be supervised, but only if it is absolutely necessary, the premier said.
"This will be in addition to the state of emergency that's operated throughout", Andrews said. "This means that police and others have additional powers".
"We can no longer have people simply out and about for no good reason whatsoever", Mr Andrews said.
Decisions would be based on state and national modelling, which Mr Andrews wanted publicly released. Meanwhile, the rest of the state will be placed under the stay-at-home restrictions that metropolitan Melbourne is now under.
'We can suspend various acts of the parliament and make sure that we get the job done and there's no question about the enforceability and the way in which new rules will operate'.
"If you take further steps you've got to make sure you've put it through properly, that the rules can function and that any changes to the rules will actually deliver the desired outcome".
Premier Dan Andrews has confirmed the rumour circulating Melbourne for days will soon come to fruition: the city is moving to stage-four lockdown restrictions. Under the new restrictions, they would have to stay within 5 kilometres (3 miles) of their homes, with only one person from each household allowed to go to grocery shopping.
Metropolitan Melbourne will be under a nightly curfew, between the hours of 8pm to 5am, from Sunday night with some exemptions for those providing care and travelling to and from work.
Regional Victoria will move to stage three restrictions from Thursday.
Seventy-three of the new cases are linked to known outbreaks while 598 remain under investigation.
Premier Daniel Andrews said he understood the deaths of a man and woman in their 80s and a woman in her 90s were linked to aged care, where 1008 cases are now active.
Cases of coronavirus in Victoria have reportedly climbed to another astounding high with more than 600 new infections recorded across the state.
