MILDURA has again recorded no new cases of coronavirus as the growth rate of the killer bug has now been kept below one per cent for seven days in a row across the country.

There were nine new cases recorded in Victoria on Sunday after a spike of 17 on Saturday.'

Victoria's Chief Health Officer Professor Brett Sutton said the increase in the number of people testing positive for COVID-19 over the weekend was to be expected due to the increase in testing.

"Victoria is increasing its testing for COVID-19. More testing means we get a clearer picture of how the virus is spreading and are able to take better steps to contain transmission," he said.

"We thank those Victorians who overwhelmingly are doing the right thing by staying at home, but we must keep at it to save lives.

"Everyone who's unwell must isolate themselves and everyone who's been told they're in quarantine either as a returned traveller or close contact must do so."

"Physical distancing will save lives. Everyone needs to comply with restrictions in place to keep yourself, your loved ones and the whole community safe. Our message is clear: if you can stay home, you must stay home."

Mildura has not had a new case in more than a week, with a total of five cases recorded overall. It's not known if all those cases have now been listed as recovered.

Swan Hill has also remained on a total of just three for more than a week.

Health Minister Greg Hunt said on Sunday that Australia had achieved "a sustained and genuine flattening of the curve", with a hope that elective and IVF could be recommenced within a week as social distancing eases pressures on hospitals.

The total number of coronavirus (COVID-19) cases in Victoria is 1328. Three of the nine new cases on Sunday were people who had recently arrived from overseas and were diagnosed in mandatory quarantine in city hotels.

There was one new death reported yesterday, a man in his eighties who died in a Melbourne hospital on Friday. To date, 15 people have died from coronavirus in Victoria.

There are 134 confirmed cases of coronavirus in Victoria that may have been acquired through community transmission. Two cases attributed to community transmission have now been attributed to a known source after further investigation.

Of the total 1328 cases, there have been 1053 in metropolitan Melbourne and 239 in regional Victoria. Several cases remain under investigation.

There are only four reasons for Victorians to leave their home: food and supplies, medical care and care giving, exercise, and work or education.

Police have strong powers to enforce these directions and can issue on the spot fines, including up to $1,652 for individuals and up to $9,913 for businesses.

Under the State of Emergency people who don't comply could also be taken to court and receive a fine of up to $20,000. Companies face fines of up to $100,000.
