Victoria's coronavirus outbreak has grown again as residents anxiously wait to see if its "circuit breaker" lockdown will finish after an initial five days.
The Department of Health confirmed an additional two locally-acquired cases on Tuesday morning.
The two cases are linked to the Holiday Inn cluster, which now stand at 19 cases.
They are both household contacts of previously identified cases.
The state is currently on day four of a five-day lockdown, however both Chief Health Officer Brett Sutton and Premier Daniel Andrews have refused to rule out it will continue beyond Wednesday.
Professor Sutton said it was "critical" any further cases must come from already identified contacts if lockdown was to be lifted.
There were 23,590 tests received in the previous 24 hours and two cases identified in hotel quarantine.
Overnight, two new exposure sites were revealed.
Both are linked to Monday's case of a COVID-positive woman who worked at psychiatric wards in Broadmeadows and Epping.
They involve Sacca's Fruit World at Broadmeadows and the fruit and meat section of Broadmeadows Central shopping centre in Melbourne's north.
Anyone who visited the greengrocer between 12.15pm and 1.15pm on Tuesday, February 9 has been told to isolate and get tested, while those at the second site from 12.30pm to 1pm on the same day should monitor for symptoms.
Mr Andrews is expected to address the media later on Tuesday.
