VICTORIANS have had "a wake up call" to check in, after a positive COVID-19 case dined at a Melbourne restaurant.

Health authorities are treating the restaurant Curry Vault as a Tier 1 exposure site, but say not all patrons who dined on May 7 had checked in.

The man tested positive for COVID-19 on Tuesday morning, after being swabbed on Monday. He had returned to Melbourne a week earlier, after travelling from overseas and quarantining in South Australia.

Other news:

Health authorities have confirmed the man's primary contacts had tested negative for COVID-19.

A full list of Melbourne exposure sites is available on the Department of Health website, including tier one sites Pact Retail Accessories in Altona North, Woolworths Epping and Indiagate Spices and Groceries in Epping.

Anyone who was in these locations has been told to get tested immediately and quarantine for 14 days.

Metro Trains services between Craigieburn and Southern Cross are among the sites listed as tier two, requiring patrons to get tested and isolate until they have a negative result.

Health Minister Martin Foley said it was vital Victorians stepped up to use the QR check in services on offer at venues.

Mr Foley said several patrons and staff at Curry Vault had tested negative for COVID-19, but the QR code check in wasn't widely taken up.

He said contact tracing teams were working through QR codes, financial transactions and takeaway transactions to find patrons yet to come forward.

"This is a reminder that the quality and speed of the public health response is directly linked to the record keeping," Mr Foley said.

"The most important thing you can do ... is to check in.

"This is a wake up call to both operators and patrons to step up and use the services that are on offer."

Mr Foley said the government had ramped up testing capacity throughout the state.

He urged Victorians to maintain COVID-19 safety protocols, such as wearing masks and hand hygiene.

Mr Foley said receiving a vaccine was one of the most important things Victorians could do to fight COVID-19.

Exposure site information is available on the Department of Health website.
