Melbourne emerged from two weeks of lockdown on Friday, following a climb in local cases since late May, there are now 74 active cases in the state, including returned travellers in hotel quarantine.
The state's deputy chief health officer, Professor Allen Cheng, said, "while it's the judgement of the public health team that we are in a position to ease restrictions, these new cases are really the strongest reminder that we are, by no means, out of the woods yet".
Australia's Victoria state said new locally acquired cases of COVID-19 rose slightly on Thursday as state capital, Melbourne, prepares to come out of a two-week hard lockdown to contain its latest virus outbreak.
"I think in the last three or four days where we have lower testing numbers and you're picking up on one or two, that is concerning", he said. "This case has done all the right things from our initial interviews, the individual recognised that they had symptoms, got tested and had a test result all within the same day", Mr Foley said.
Victorian contact tracers are working to pinpoint the source of the infection, with investigations revealing one of the cases checked in near the Craigieburn Central shopping centre on May 23.
"My personal view is that there is certainly more cases out there".
However, the emergence of mystery cases like the man's continues to concern authorities because they can "linger and build".

They will not need to isolate or be tested once they land in New Zealand.
