A traffic controller who works at a COVID-19 testing site at Moonee Valley in Melbourne has become a 9th case reported today.
Health Minister Martin Foley said the case, who was not an existing close contact, had symptoms begin on Monday evening, was tested on Tuesday and received a positive result this morning.
"The site has been closed," he said.
"This is very early information, it's literally just dropped into the system."
The Chief Health Officer Brett Sutton said the risk from a test site was low for those driving through but acknowledged there could be a risk if they wound down their window to speak to the controller.
The government is still working through details.
Health Minister Martin Foley said it was "a bit early" to speculate on what implications this new case might have.
Eight new coronavirus cases have been recorded in Victoria on the day residents exit lockdown.
All eight cases are related to current outbreaks and were in quarantine during their infectious period.
There were 35,862 tests were received and no new hotel quarantine cases recorded.
Victoria's 12-day lockdown ended at midnight but a number of restrictions remain for two weeks before being eased again.
Restrictions include no visitors being permitted at people's homes and masks being mandatory indoors and outdoors. Public gatherings of up to 10 people are permitted.
Restaurants, bars, cafes and pubs can reopen with a maximum cap of 100 people inside and 300 people outside and a density quotient of 1 person per 4 sqm.
Victorian Chief Health Officer Professor Brett Sutton said people should still visit people, but just not at their homes.
"Although you can't visit homes, if there are loved ones you haven't seen, see them in a park, go for a walk outside, wear a mask and catch up with them but please don't visit homes," he said. "That rule is very important."
