On Monday, chief health officer Brett Sutton said he was unsure whether lockdown would end later this week in regional Victoria.

"At the moment, it's reviewing day by day," he said.

"I don't what might emerge tomorrow. There are still a number of primary close contacts in regional Victoria - a number who've tested negative - but we don't know what might be round the corner."

Authorities administered more than 20,000 vaccinations on Monday with another 42,699 people tested for the virus.

On Tuesday, the state entered its fifth day of lockdown with only five essential reasons to leave home.

Other news:

The five reasons are work or education, caregiving, food and supplies, exercise for two hours and to go and get vaccinated.

Meanwhile on Sunday, Victorian Treasurer Tim Pallas announced a $250 million support package to help impacted businesses through the lockdown, something Bendigo businesses welcomed.

Business, industry and union groups have also welcomed the package but argue the federal government must also step up.
