Victoria has recorded six new locally acquired Covid-19 cases on Thursday as the state enjoys its second day of freedom from a fifth lockdown.
The health department confirmed seven new local cases about 8.30am, but one – a mystery case – was previously announced on Wednesday.
The health department said all new cases bar the mystery case were linked to existing outbreaks and all except one were in isolation for their entire infectious period.
The mystery case worked as a traffic controller at a drive-through testing site at Moonee Valley racecourse in Melbourne’s northwest and returned a positive result on Wednesday morning.
Health authorities are still trying to trace how the man acquired Covid-19, with the testing site a key area of focus.

The testing site was closed for deep cleaning with the health department intending to reopen the clinic on Thursday.
The positive case worked two shifts while infectious and all staff at the now-closed site during that time had been sent home to isolate.
Victoria’s chief health officer Brett Sutton said the case illustrated the state was not “risk free” and reinforced how infectious the Delta strain was.
“It’s not over, there will be ongoing risks and there will be ongoing potential for incursion into Victoria,” he said.

Victoria has recorded 204 cases linked to the two outbreaks that jumped the border from Sydney’s deadly Delta cluster – one from a team of Sydney removalists who transited through the state and the other from a family who returned to Melbourne’s north from a NSW red zone.
More than 20,000 primary close contacts have been identified during the state’s latest outbreak, with at least 11,000 of those cleared from isolation so far.
No new cases were recorded in returned travellers in hotel quarantine, with the number of active cases in Victoria at 205 — down from 206 on Monday.
