Victoria has recorded 75 fresh COVID-19 cases, bringing the state’s confirmed total to 2099.
The state has 288 active cases and nine are in hospital.
One new case was linked to hotel quarantine and 14 are linked to known outbreaks, Health Minister Jenny Mikakos said on June 29.
Another 37 cases were detected through routine testing and 23 are still under investigation, with both groups possibly linked to known outbreaks.
There has been a net increase of just 71 cases as four previous cases have been reclassified.
“We are obviously concerned by the increasing number and upward trend, and we are monitoring the situation very closely,” Mikakos said.
More than 792,000 tests have been done in the state, about 53,000 in a blitz on suburbs experiencing the latest coronavirus hotspots and more than 15,000 completed since Sunday.
“Many of the cases that have come through today, they are overwhelmingly concentrated in those priority suburbs,” Mikakos said.
Saliva testing also rolled out in Keilor Downs on Sunday.
Monday’s total case increase is the highest daily total in the state since April 2, when 68 cases were detected.
Victoria recorded 49 cases on Sunday, with the state grappling with double-digit increases for almost two weeks.
Health authorities are considering putting Victoria’s coronavirus hotspots in lockdown as the number of new infections in the state balloons.
