Victoria has recorded another 275 coronavirus cases overnight and a woman in her 80s has died from the illness.

It brings the total number of cases seen in the state since the start of the pandemic to 5942.

Thirty-nine people in Victoria have died to date.

Of the new cases, 28 are linked to known and contained outbreaks and 247 are under investigation.

Currently there are 147 people being treated in hospital for the illness and 31 of those are receiving intensive care.

Premier Daniel Andrews said more than 1.3 million tests had been conducted in Victoria since the start of the year, which was one of the highest testing rates in the world.

Mr Andrews said more than 26,500 tests were conducted over the past 24 hours.

He warned against thinking that a corner had been turned because the number of new cases had fallen.

"We had a very big day Friday, we then had a substantial drop-off, even though we had done more tests," Mr Andrews said.

"This shows you that it is a wicked enemy. It is unstable and until we bring some stability to this, we won't be able to talk about a trend."

He said the government was watching "every regional case very, very closely", but there was no advice as yet on changing the restrictions in regional Victoria.

Updated case figures for each municipality should be released later today.

As of Sunday, the City of Greater Bendigo had recorded a total of 14 cases, with four of those still active.

Macedon Ranges Shire also had four active cases, from a total of 13.

There were no other active cases across the region.
