Three primary household contacts of the man have tested negative for coronavirus, the state government confirmed.

Health minister Martin Foley and chief health officer Brett Sutton briefed the media on Tuesday afternoon.

He said a secondary test had confirmed the man, aged in his 30s, had returned a second positive test.

Mr Foley announced three 'tier one' exposure sites linked to the man - a curry restaurant in Melbourne's CBD and two stores in the outer northern suburb of Epping, including a Woolworths supermarket.

"Contact tracing is well underway," Mr Foley said.

Mr Foley said work was being done to establish when the man was infectious, and whether that was during his flight back to Melbourne from Adelaide after a stint in quarantine.

The man had returned to Australia from India, via the Maldives and Singapore, Mr Foley said.

Mr Foley used the case as a chance to promote the benefits of vaccination.

"This case is a reminder that we are still in the grip of a global pandemic."

More news:

Mr Sutton said no changes were planned to current coronavirus restrictions in Victoria.

"We're not foreshadowing anything," he said. "The good and recommended advice is good advice for all times. People should wear masks if they can't physically distance from others, especially in indoor settings.

"People should also check in with QR codes."
