Thousands of people have taken to the streets of Sydney and other Australian cities to protest against lockdown restrictions amid another surge in coronavirus cases.

The unmasked participants marched from Sydney’s Victoria Park to Town Hall in the central business district, carrying signs calling for “freedom” and “the truth”.

There was a heavy police presence in Sydney, including mounted police and riot officers in response to what authorities said was unauthorised protest activity. Police confirmed a number of arrests had been made.

New South Wales (NSW) Police said it recognised and supported the rights of free speech and peaceful assembly, but the protest was a breach of public health orders.

A police statement said: “The priority for NSW Police is always the safety of the wider community.”

The protest comes as Covid-19 case numbers in the state reached another record with 163 new infections in the last 24 hours.

Greater Sydney has been locked down for the past four weeks, with residents only able to leave home with a reasonable excuse.

State health minister Brad Hazzard said: “We live in a democracy and normally I am certainly one who supports people’s rights to protest … but at the present time we’ve got cases going through the roof and we have people thinking that’s OK to get out there and possibly be close to each other at a demonstration.”

In Melbourne, thousands of protesters without masks turned out downtown chanting “freedom”. Some of them lit flares as they gathered outside Victoria state’s Parliament House.

They held banners, including one that read: “This is not about a virus it’s about total government control of the people.”

A car protest rally is also planned in Adelaide, which is also under lockdown, with police warning they will make arrests over unlawful activity.

By Friday, 15.4% of the nation’s population aged 16 and above had received both jabs for Covid-19.

“We’ve turned the corner, we’ve got it sorted. We’re hitting the marks that we need to make, a million doses a week are now being delivered,” Prime Minister Scott Morrison said. “We are well on our way to where we want to be by the end of the year and potentially sooner than that.”

The federal government said it will send thousands of extra Pfizer doses to Sydney while adults in Australia’s largest city are also being urged to “strongly consider” AstraZeneca in view of the scarcity of Pfizer supplies.
