In another promising sign, health officials confirmed both cases were linked to existing outbreaks.
"The two new locally acquired cases are primary close contacts of existing case, with no community exposure during their infectious period," the health department said.
There are now fewer than 2000 active primary close contacts in isolation in Victoria after more than 6400 contacts were cleared.
But there have been concerns among authorities about a drop in testing numbers after just 17,102 were processed in the 24 hours to Sunday morning.
