The two infections are household contacts of a known case, a worker who had previously tested positive.

Victoria’s health department confirmed the new infections in a tweet.

“Interviews are underway and known exposure sites will be published online … as soon as possible,” authorities said.

Details of the new infections came after three workers and two residents, both released from quarantine before testing positive, were diagnosed with coronavirus, and linked to the outbreak.

A family of three had earlier been identified as the epicentre of the hotel cluster. They were infectious before arriving in Victoria.

One of the residents who tested positive after being released from quarantine visited two bank branches in Glen Waverley.

Commonwealth and HSBC banks in Glen Waverley have been listed as exposure sites.

They join several venues in Sunbury, including a busy shopping centre and a bottle shop, which were added to the alerts list earlier in the week.
