The Victoria figures mark another record-breaking jump in infections, surpassing Tuesday's tally of 14,020.
The new cases were detected from 59,682 test results, taking the test positivity rate to nearly 30 percent.
But the true figure is likely much higher, as the PCR testing network is overwhelmed by the rapid rise in cases.
There are now 51,317 active cases of the virus, and 731 people have died in the current outbreak.
