Victoria has recorded 79 new locally acquired Covid-19 cases as the state's lockdown shows little signs of suppressing the Delta variant.
The Department of Health said on Friday that 26 of the latest cases were unlinked at this stage.
The department is yet to confirm how many cases were infectious in the community.
Daily cases rose to 80 on Thursday, nearly double Wednesday's total of 45. Thursday's total was the record for the state's latest outbreak.
The virus is continuing to spread in regional Victoria including a case in an aged care worker in border community Echuca, the ABC reported.
At least six of the latest cases have emerged in Shepparton, and follows 18 announced on Thursday.
About 16,000 residents in the region, which has a population of 65,000, are believed to be self-isolating.
About one in 10 of the state's cases are in the regional town which has left local authorities needing assistance to distribute relief packages to those in isolation.
Goulburn Valley Health chief executive Matt Sharp said work was being done to reclassify some exposure sites, meaning a reduction in those required to isolate for two weeks as the town struggles under the mass isolation orders.
Friday's total brings the number of active cases in the state to 660.
More than 50,000 tests were performed in the previous 24-hour reporting period while 33,611 vaccine doses were administered.
