Australian authorities will deploy about 1,000 police officers on Saturday to an illegal anti-lockdown protest in Sydney amid fears it will escalate the Covid-19 outbreak in the city.

"Please don't come into Sydney tomorrow to protest. If you do, you will be met by up to a thousand police who will be ready to deal with you, whether that be via the health orders or other laws," New South Wales Police Commissioner Mick Fuller said.

The call for the march, which violates stay-at-home orders and a ban on gatherings imposed by the NSW government in the wake of an outbreak of the Delta variant, follows last Saturday's protest of thousands of people in Sydney and other cities.
