Victoria police clashed with anti-lockdown protesters in Melbourne on Saturday afternoon, as the Australian state recorded another 535 new coronavirus cases and one death.Around 1,000 protesters gathered in the north-eastern suburbs of Richmond and Hawthorne, forced to make a last-minute change of location after 2,000 police officers formed a “ring of steel” around the Melbourne CBD.Public transport to and from the city was suspended between 8am and 2pm on Saturday, and police set up road checkpoints, barricades and roving patrols around the city in an effort to thwart the protest.Barricades of police officers originally managed to confine protesters on Burnley Street in Richmond. That was until some protesters opened the locked gate to a residential apartment complex, allowing them to escape authorities on to Bridge Road.Footage from the ground showed protesters clashing with police on several occasions.At one point, protesters were filmed throwing objects – including water bottles and a traffic cone – at police, who had formed a human barricade, blocking the march. In response, police deployed pepper spray.Protesters were also filmed charging at and breaking through the police line.

They said 265 infringement notices had been issued for a range of breaches including failing to wear a face mask, 232 of which were in metropolitan Sydney.“I’m pleased to see that common sense has prevailed and the vast majority of people have complied with the existing public health orders,” the police minister, David Elliott, said.Some 1,700 officers were deployed across the state to manage the potential protests.“Today’s operation has been very successful. Our aim was to prevent the protest activity going ahead … and if you have a look at the results you will see our actions have been well received by the public,” the police assistant commissioner, Peter Thurtell, said.Brisbane also saw a sizeable anti-lockdown protest take place, despite the fact that the state is not in lockdown.Victoria’s announcement of 535 new Covid-19 cases is the state’s highest recorded daily total this year and brings the total number of active infections to 4974.Only 62 of today’s cases were linked to known outbreaks.Authorities said that a woman in her 70s from the greater Shepparton region had died from Covid-19.Sign up to receive the top stories from Guardian Australia every morningKate Matson, from the Victoria Department of Health, said they were particularly concerned about 62 new cases in the northern suburb of Craigieburn, and 15 new cases in regional Victoria.The Victorian health minister, Martin Foley, told reporters that the state’s contact tracing system was struggling to keep up with the surge in daily cases, meaning it was taking longer for them to contact those who are testing positive for Covid-19.“I don’t think it indicates the system being overwhelmed, it indicates that the system clearly is under pressure,” Foley said.A man is arrested by police on Victoria Street, Richmond.
