Victorian Premier Daniel Andrews says it's still too early to know whether the state's lockdown can end as planned after 11 new local COVID-19 cases were recorded.
All of the new cases were linked to known outbreaks and were in quarantine throughout their infectious period.
"The strategy is working but it's still too early for me to be able to tell Victorians what will happen at midnight on Tuesday night," the premier told reporters on Sunday.
"There is still a couple of days to go, and as we know ... things can change. This is fast-moving."
Victorian cabinet ministers and the public health team will meet on Sunday night and Monday to discuss the easing of COVID-19 restrictions.
Mr Andrews expressed his dismay at but said he was reasonably confident it would not be found to be a super-spreader event.
The rally was brought to a violent end as police used pepper spray to clear the crowd.
Penalty notices were issued to 73 people as a result of the action. More fines are expected.
"We don't want to see people out and about selfishly putting their point of view ahead of the health and wellbeing of others," Mr Andrews said.
"Everybody is entitled to an opinion, but you're not entitled to put other people in danger.
"And that's what yesterday was about. Ultimately, selfish behaviour that puts many other people in real danger."
Mr Andrews said it had been a difficult task to shut down the mass gathering without that in itself becoming an infection control nightmare.
"People understand that Victoria Police did their very best," the premier said.
"But you know, we can't vaccinate against selfishness and these people should be ashamed. Absolutely ashamed. It's just wrong."
COVID-19 Commander Jeroen Weimar described protesters as a "small minority having a self-indulgent tantrum".
Some 32,385 virus tests were processed in the 24 hours to Sunday morning, while 17,370 Victorians received a vaccine dose at one of the state-run hubs.
There are more than 22,000 people self-isolating across the state after being deemed close contacts of positive cases, while there are more than 380 exposure sites.
