VICTORIAN authorities say the state's run of four zero community transmission days is reassuring, but the battle against COVID-19 won't be won until the Australian population is vaccinated.
Health Minister Martin Foley urged the community to remain vigilant about the coronavirus.
Mr Foley thanked Victorians for the efforts to stop the spread of COVID-19 after the Black Rock cluster.
"It's not an achievement we can rest on our laurels though, because we know that as 2021 evolves, this isn't over until the Australian population is vaccinated," he said.
SIX new COVID-19 cases have been diagnosed in Victoria on Sunday, all confined to hotel quarantine.

These include pre-flight testing of returning Australians, mandatory masks on domestic and international flights and a limit on international arrivals to certain states.
