Victoria has recorded another two locally acquired cases of Covid-19 in the past 24 hours to midnight as the state enters its second day of a five-day lockdown.
A third case has also been recorded in hotel quarantine after 21,475 tests were administered, the Department of Health said on Sunday.
This brings the number of active cases in Victoria to 22.
The new local cases are linked to the Holiday Inn Melbourne Airport cluster, which has 16 confirmed infections. They are a woman and child from different households.
The health department also released a list of new Tier 1 exposure sites including Woolworths at Broadmeadows.
Anyone who went to these locations must self-isolate immediately, receive a Covid test and remain isolated for 14 days.
Those who visited the site outside of the exposure times are being asked to monitor for symptoms and get tested should they present.

Asthma treatment device blamed for Covid spread
The outbreak can be traced back to a family of three who quarantined at the Holiday Inn and are believed to have been infected overseas.
One family member, a man now in intensive care, used a medical device for his asthma called a nebuliser in their hotel room, despite them being banned outside of medi-hotels.
The nebuliser's use has been attributed to spread of coronavirus at the Holiday Inn.
The man hit back at what he felt was authorities' criticism of him in an article in The Age newspaper, claiming he had declared the nebuliser to medical staff at the hotel.
On Saturday however, head of the state's hotel quarantine authority Emma Cassar denied he told staff about it.
"I can categorically say that there is no evidence from our audit that he has raised this with our health team," she told reporters.
Ms Cassar said the man had been badly treated by the media and she was sorry about his experience.
"We have never accused him of doing the wrong thing," she said.
