Victorian Premier Daniel Andrews has announced 671 new cases of COVID-19 and seven deaths along with new stage four restrictions.
He said a state of disaster has been declared from 6pm on Sunday in addition to the state of emergency.
Metropolitan Melbourne has been put under a curfew from 8pm tonight. This will run from 8pm to 5am every day.
“The only reason to be out of your home between the hours of 8pm and 5am is to get care, to give care, or to go to and from work or be at work. We can no longer have people visiting others. We can no longer have people simply out and about for no good reason whatsoever,” Mr Andrews said.
Recreational activity has been banned and exercise limited to one hour each day.
Regional Victoria will also go into stage three restrictions from midnight on Wednesday.
The restrictions will apply for six weeks.
Mr Andrews said regional Victoria will move to stage three restrictions.
"It is with some regret but given the significant community transmission and the growing case numbers, and the fact we need to stay ahead of this in regional Victoria, from midnight next Wednesday, regional Victoria will move to stage three restrictions," he said.
"That's stay at home, except for the four reasons to leave. That will mean restaurants, cafes, bars, gyms, a whole range of other settings will need to close from midnight next Wednesday.
"That is not the position we wanted to be in but we cannot have a situation where this continues to grow and grow in regional Victoria and then we have a situation where as we are perhaps bringing stability and reduced numbers to metropolitan Melbourne, we have a problem that is even larger and spread right across regional Victoria.
"We just can't have that. So those changes will come into effect from midnight Wednesday night. That gives all of those who are most affected, that gives them time. The time will be important to businesses who will need to move to a home delivery or takeaway only model."
