Australia reported 1,607 new coronavirus cases on Sunday as states and territories gradually shift from trying to eliminate outbreaks to living with the virus, according to Reuters.

Victoria, home to about a quarter of Australia's 25 million people, recorded 507 cases as its premier said a weeks-long lockdown will end once 70 per cent of those 16 and older are fully vaccinated, whether or not there are new cases.

Premier Daniel Andrews said the state might reach that vaccination threshold around Oct 26. About 43pc Victorians have been fully vaccinated and just over 46pc people nationwide.

"We will do so cautiously, but make no mistake, we are opening this place up. There is no alternative," Andrews said. We "cannot perennially or permanently suppress this virus. Lockdowns have been about buying time to get to 70pc and 80pc vaccination."
