Victorian health authorities are scrambling to find close contacts of a second coronavirus case in the state with links to an outbreak in Sydney.
The man, who works at a dry cleaning business in the Melbourne beachside suburb of Sandringham, returned a positive test late on Thursday afternoon.
His family has been isolated and are being tested, with the state public health department saying it is urgently trying to understand his movements.
QR code data from the business is being analysed, while his close contacts are being identified and contacted.
The man was a close contact of another worker at the dry cleaners, a man from Oakleigh who tested positive on Wednesday after going to a party at his daughter’s house in West Hoxton in Sydney on Saturday night.
The gathering has since been declared a super-spreader event, with more than 12 attendees having become infected.
The Oakleigh man, who is aged in his 60s, returned to Melbourne on Jetstar flight JQ523 that left Sydney at 5.30pm on Sunday.
The flight and terminal four of Melbourne airport have been listed as tier one exposure sites, as has the dry cleaning shop, which is shut for deep cleaning.
The Oakleigh man developed symptoms late on Tuesday night at his apartment complex home, where he lives alone.
The health department says a “risk assessment” is being undertaken at the complex and support will be provided to other residents.
Victoria has declared greater Sydney, the Central Coast, Shellharbour, Blue Mountains and Wollongong as “red zones” under its travel permit system.
The Oakleigh man travelled back to Victoria from a Sydney suburb that was considered to be “green zone” at the time.
