Victoria recorded another 439 cases of COVID-19 and 11 deaths in the past 24 hours.
All of the deaths are connected to aged-cared facilities.
Premier Daniel Andrews has announced tougher enforcement of COVID-19 rules.
He said a range of new penalties were being introduced.
He said the Australian Defence Force and authorised officers from the Department of Health and Human Services have conducted more than 3000 doorknocks but in 800 homes the person who was meant to be isolating wasn't there.
Mr Andrews said residents isolating at home were no longer allowed to leave their home to exercise and cannot move beyond their front yard.
More than 500 additional ADF personnel will come to Melbourne and an additional 300 DHHS staff would be rostered on to doorknock.
Mr Andrews said people found not isolating at home would be given a new on-the-spot fine of $4957 for breaching isolation.
It's the largest on-the-spot fine on the Victorian books.
"You have got to be isolating when you are directed to do so," he said.
A repeat of coronavirus breaches may lead to an appearance in the Magistrates Court and a $20,000 fine.
Mr Andrews said people who have tested positive, their close contacts and people who are awaiting test results must all isolate.
Police Minister Lisa Neville said most Victoria were doing the right thing, but a minority of people were knowingly doing the wrong thing and putting lives at risk.
"It's ridiculous and it's dangerous," she said.
Ms Neville said police would be enforcing stage four restrictions including the curfew in Melbourne and would be enforcing stage three restrictions in regional Victoria.
"Extraordinary powers for an extraordinary time," she said.
Ms Neville said dozens of people knowingly breached the curfew including someone who was bored and wanted to go for a drive and another person who wanted to buy a car.
She said Victoria Police have the power to detain people who continue to breach self-isolation rules or who continue to go to work against restrictions.
Chief Commissioner Shane Patton said enforcing the Chief Health Officer's orders was the most important commitment Victoria Police had currently.
Mr Patton said a small group of "sovereign citizens" had been baiting police and had even assaulted an officer after being asked to wear a mask.
He said on a number of occasions in the few weeks police had to break car windows and pull people from the car to make them provide their details.
Mr Andrews, Police Minister Lisa Neville and Chief Commissioner Shane Patton will speak from 11am.

On Sunday, Mr Andrews declared a state of disaster for the entire state, which provides additional powers to police.
Under the new restrictions, Melbourne has entered stage four restrictions while regional Victoria has returned to stage three.
