Thousands of demonstrators have swarmed the steps of Victoria's parliament building to protest against the state government's proposed pandemic laws and mandatory vaccination.
The state recorded 1268 new locally acquired COVID-19 cases and seven deaths on Saturday.
Chanting "kill the bill", protesters wielding signs including 'save our children' and 'Vaxtoria' gathered outside parliament from about midday on Saturday.
A woman addressed protesters just after 2pm, saying the Andrews government's proposed bill is "unlawful" and "needs to be invalidated".
Shortly after, a man took to the stage and said "thank you my fellow superspreaders", which was met with applause.

"This is only the beginning, this is the start of the people's revolution. We are the counter revolution and we will continue to march."
The protesters say they will march to the governor's residence, and have vowed to return next weekend to hold a similar protest.
