Victoria's Health Minister says the state can still get control over a growing COVID-19 outbreak, but the number of unlinked and regional cases are "of great concern".
The state recorded 65 new infections on Saturday.
Of the new cases, 55 are linked to current outbreaks and 10 are under investigation.
Just 12 of the new cases were in isolation for their infectious periods.
Health Minister Martin Foley said a new case recorded this morning in Mansfield, in regional Victoria, would be officially included in Sunday's total.
The infection is linked to the growing outbreak in Shepparton, in Victoria's north-east, which prompted the reimposition of a statewide lockdown on Saturday.
Goulburn Valley Health confirmed on Sunday afternoon that a further two infections had been recorded in the area, bringing the total to 23.
Those cases will be included in Sunday's official tally and reported on Monday morning.
Mr Foley said, despite the rise in cases, he was confident the outbreak could be contained if people followed lockdown rules, got vaccinated and tested.
"We're still in the realm of hauling this back," he said.
"What we've seen is more cases pop up in areas, whether it be Shepparton, Mansfield, the Royal Melbourne and other parts of metropolitan Melbourne that are of great concern."
There are now 440 active cases of COVID-19 in the state, with 103 of those aged below nine.
There are 27 people now in hospital with the disease, which Mr Foley said was a "significant jump". He said there was a greater proportion of young people in hospital than in previous outbreaks.
More than 100 new venues were added to Victoria's list of exposure sites on Saturday, and more than 11,000 close contacts are in quarantine.
Three of the cases announced on Sunday are linked to the Royal Melbourne Hospital, and another three would be included in Monday's numbers, taking the current outbreak at the hospital to seven cases.
Authorities believe the first person infected in the cluster was a man from Shepparton undergoing surgery at the hospital on August 12.
Victorian Department of Health Deputy Secretary Kate Matson said she expected more cases to emerge at the hospital.
"There's a number of patients and staff, as well as a visitor to the hospital," she said.
Wastewater testing was continuing to show evidence of the virus across Melbourne, even in areas where there had been no confirmed cases.
There have been repeated daily detections of the virus in wastewater from the Sunshine West industrial area from August 8 to August 20, but no cases linked to that area have been found.
"If you work in that area and you haven't yet been tested, please do so," Ms Matson said.
"Our teams are working as hard as they possibly can to get on top of this, Victorians can work equally as hard by getting tested as soon as you've got a slight sniffle, gastro symptoms, a headache is a symptom of coronavirus," she said.
The new cases were identified from 44,147 test results received on Saturday.
There were 26,149 doses of vaccine administered at state-run sites.
Chief Commissioner condemns 'selfish' protesters
Victoria Police Chief Commissioner Shane Patton has condemned people who attended Saturday's anti-lockdown protest in Melbourne.
More than 250 people were arrested at the demonstration, and more than $1million in fines were handed out.
One police officer remains in hospital after being knocked to the ground, punched and kicked by protesters.
Chief Commissioner Patton said flares, marbles and ceramic insulators were thrown at police, resulting in nine officers being taken to hospital.
"That's not about protesting about freedom, that's criminal activity," he said.
He said there were a small number of families and children who attended the protest, but the vast majority were men aged between 25 and 40.
"The vast majority of Victorians did not come out yesterday, we had the selfish few yesterday."
Two people have been remanded in custody in relation to the officer who remains in hospital, and another 19 people will face court at a later date.
There are concerns the event could lead to spread of the virus in the community, with a number of cases still unlinked.
Paid leave for public sector workers to get vaccinated
Mr Foley announced that all public sector workers would be entitled to half a day's paid time off to get vaccinated.
The payments are available for appointments for both first and second doses of a vaccine, and apply to full-time, part-time, and long-term casual staff.
Mr Foley said there would also be another aged care workforce vaccination "blitz".
Residential aged care and disability workers will be able to walk up to any of the more than 50 state vaccination hubs and get vaccinated with the shot of their choice.
"We know that residential aged care and disability workforces are so critical to protecting our most vulnerable citizens and community members from COVID-19," Mr Foley said.
Financial support for regional businesses
Victorian Jobs Minister Martin Pakula has announced $146.6 million in financial support for 20,000 regional businesses affected by the lockdown.
There would also be another round of payments for Alpine businesses as the state's ski season takes a hit from statewide restrictions.
"We welcome the Commonwealth having again made a 50 per cent contribution of that package, and that ongoing partnership with the Commonwealth during this very difficult period allows us to do what we're doing at the moment," he said.
"The details of that package is that the business cost assistance program, like the metropolitan program, will have payments of $2,800 a week, so $5,600 between now and the second of September."
