Victoria has recorded 22 new locally acquired Covid-19 cases the day after the state's lockdown was extended.
All of today's cases are linked to known clusters.
Premier Daniel Andrews announced yesterday that lockdown would continue until at least Tuesday, July 27 at midnight.
"We wish we could bring this in earlier, but we can't run the risk that there are cases out there that we don't know about," he said.
"There are changes of transmission that are not yet contained that we don't know about and if we would open up we would see how quickly this runs, we see how challenging this can become in a very short space of time."
