About 300 people have gathered in Sydney's CBD to protest Aboriginal deaths in custody after the NSW premier implored people to avoid planned rallies amid the COVID-19 pandemic.
Protesters were outnumbered by more than 600 police officers in the city on Friday night, in an event deemed unlawful because NSW Police wasn't formally notified.
Protesters chanted "Black lives matter" and "Not enough justice, too many coppers" while marching through Hyde Park.
The peaceful action was relatively brief, with police on horseback and foot forming a perimeter around Hyde Park's Captain Cook statue as marshals began calling for people to disperse, go home and stay safe.
A crowd at Town Hall later broke up when police issued a final warning.
It comes after the Supreme Court prohibited another protest to "Free the refugees" scheduled for Saturday afternoon on the basis the health risks "outweigh the rights of public assembly and free speech".
Premier Gladys Berejiklian on Friday asked people not to put the police in a difficult position.
"Please respect the health orders, please respect the verdict of the Supreme Court," she told 2GB radio.
"These protests aren't legal, they're a public health risk. Please don't risk your own safety and don't risk getting a fine by being out there tonight or tomorrow.
"We just hope everything is resolved peacefully."
NSW Police top brass have warned attendees can be moved on, potentially arrested or fined $1000.
One person, a 24-year-old woman, was fined on Friday night for disobeying a move-on direction.
Prime Minister Scott Morrison on Friday stated: "The very clear message is people should not attend those events because it is against the health advice to do so."
He said protesters should express their views "in another way".
Justice Michael Walton in the Supreme Court on Thursday night granted a police application for Saturday's refugee rally be declared a prohibited public gathering.
Mr Morrison on Friday announced that under step three of Australia's COVID plan, small sporting stadiums would be able to seat 10,000 spectators or 25 per cent of the venue's capacity.
Individual states and territories will decide when to implement that change.
"(But) national cabinet reiterated that high-risk outdoor events without ticketed seating ... do not form part of step three," the prime minister said in a statement.
Meanwhile, the state's two-week streak of no new locally-acquired COVID-19 appears over after Rose Bay Public School was closed on Friday while NSW Health investigated a possible case in a staff member.
"Further testing confirmed this is a case of COVID-19," the department said in the evening.
"However, it should be stressed that the date of infection is still to be determined and this case may be an older infection."
Nevertheless, close contacts are being identified and told to self-isolate.
The state otherwise reported three new cases on Friday - two in travellers in hotel quarantine and a previous case stemming from the Greg Mortimer cruise ship off the coast of South America.
NSW Health says there have been 3115 cases to date. No one is currently in intensive care.
NSW Education Minister Sarah Mitchell announced on Friday that school sports could resume from the start of Term 3 in late July.
It follows the announcement that community sport for both adults and children will recommence in NSW from July 1, with the state government on Friday committing $27 million to aid its resumption.
Up to 12,500 local sporting clubs will receive payments of up to $1000 while payments will also be made to 95 state sporting organisations.
