As Melburnians enter their final day of a two-week lockdown, Victoria has recorded four new locally acquired Covid-19 cases.
All four cases are from the same household however the source is not yet known, the Department of Health said. Investigations into how the household acquired the virus are underway.
There has now been 90 community cases since the first were detected on May 24.
There were 23,679 tests performed in the previous 24 hours, just shy of the 25,000 Chief Health Officer Brett Sutton called for moving forward.
Prof Sutton warned further cases would continue to arise after just one local case announced on Tuesday, and he said it was possible there was still undetected community spread out there.
Significantly, the five reasons for leaving the home have been scrapped however home visitors will not be allowed, while masks must still be worn in indoor public spaces.
Health authorities said restrictions could be eased as the majority of recent cases were linked and already isolating. Unless investigators can quickly trace the source of the latest cases, they will undoubtedly be of concern to authorities.
There were 20,784 vaccine dose administered across the state in the previous 24 hours.
Victorian health authorities held an emergency meeting with their Queensland and NSW counterparts late on Wednesday over a woman who tested positive and travelled interstate.
The woman left Melbourne with her husband on June 1, when the city was in lockdown, and tested positive at the end of a road trip through NSW and into Queensland.
The woman's husband has since tested positive.
