State police charged a protester with assault after an officer suffered cuts to the head during an anti-lockdown rally in Melbourne on Saturday.
Police said seven other people were charged with breaching Covid-19 directions after some 200 people gathered to protest near the city centre.
Scuffles between demonstrators and police resulted in more than 160 fines for contravening lockdown measures or not wearing a mask.
“Despite all the warnings, it was disappointing to see individuals turn out to protest in the city, putting the lives of Victorians at risk,” a police statement said.
On Sunday, health officials said Victoria recorded 63 new cases and five more deaths. It takes the state’s total fatalities to 666 and the national death toll to 753.
Among other developments in the Asia-Pacific region, India recorded another record surge of 90,632 cases in 24 hours, as infections spread to smaller cities and rural areas.

The ministry on Sunday also reported 1,065 deaths for a total of 70,626. More than a million cases have been detected in India in less than two weeks. Authorities say India’s daily testing now exceeds one million people.
