Premier Daniel Andrews has said while the lockdown strategy was working, it was still too early to know whether Victoria would be released from lockdown on Tuesday night.
With 11 new cases of COVID-19 all already in their 14-day isolation period, Mr Andrews said the state was well-placed but things could change rapidly.
Victoria's extended lockdown is earmarked to end at 11.59pm Tuesday night, but the Premier did not commit to easing restrictions by the deadline.
Mr Andrews said the outbreak was fast-moving and dynamic.
"The strategy is working but it's still too early for me to tell Victorians what will happen at midnight Tuesday night," he said.
"At this stage though, things are going well and that is a testament to a very large group of people who are working incredibly hard to track, to test, to isolate, to trace this down and to find every chain of transmission but also to millions of Victorians doing the right thing by following the rules."
Mr Andrews said the government would meet with health officials throughout Sunday and Monday before making a decision.
"Health officials will come to us with advice as late as possible in terms of the most accurate picture and if we can give people notice, we will," he said.
"Things are strong, things are solid, but things can come from nowhere in these next couple days so we shouldn't become complacent in any way.
"We have to see thing this through and hopefully we can be in a position to ease some of these rules from midnight Tuesday night but we've got to see what tomorrow's numbers look like, and Tuesday's, as well as follow every lead, chase down every case and try to limit every chain of transmission."
Victoria has recorded 11 fresh locally-acquired COVID-19 cases.
However all were in quarantine throughout their period of infection.
Health officials say the new cases are also all linked to current outbreaks.
Victoria managed to administer 17,370 vaccine doses in the 24 hours to Sunday, with 32,385 virus tests conducted for the same period.
Chief Health Officer Brett Sutton said on Saturday the state was "on track" for a planned easing of restrictions on Tuesday but declined to confirm it.
Victoria recorded 12 new locally acquired cases on Saturday, 10 of them in quarantine throughout their entire infectious period and also all linked to current outbreaks.
The numbers continue an encouraging downward trend in new diagnoses after 14 cases were reported on Friday and 26 on Thursday.
Prof Sutton introduced a new travel designation for NSW late on Friday, making the whole state an "extreme risk zone" backdated to July 9.
This makes it difficult for Victorians in NSW to come home unless they get a rare exemption or have a Specified Worker Permit.
"It's very strict in terms of the movement of people across the border," he said.
Asked on Saturday whether Victoria could expect an easing of its own restrictions on Tuesday, as scheduled, Prof Sutton said the signs were positive but he declined to commit to it.
Health Minister Martin Foley insists the risk designation of NSW is a natural progression of attempts to protect Victoria and not to do with Premier Daniel Andrews' call for a "ring of steel" blockade around Sydney.
He also moved on Saturday to hose down the idea of tensions with NSW over a lack of willingness to redirect vaccines to Sydney's virus-ridden suburbs.
Mr Foley said Victoria and other states had "legitimate demands" on scarce vaccines for July and August which had already been allocated to them based on population.

However he welcomed recent reports of spare Pfizer doses in the national stockpile and said he'd be happy for those to be sent to NSW.
Meanwhile an anti-lockdown protest in Melbourne on Saturday was brought to a violent end as police used pepper spray to clear the crowd.
Thousands of protesters of all ages chanted "freedom" as they gathered outside Victoria's Parliament House.
"We can all argue the merits or otherwise of various approaches to managing transmission, but let's not pretend that 'marching for freedom' will actually deliver the precious freedom that we all need and desire. end," Prof Sutton later tweeted.
As of Saturday, more than 22,000 Victorians were listed as primary close contacts isolating at home, while about 2500 MCG contacts were preparing to be released from 14 days of confinement.
