The NSW Police Commissioner has warned that people protesting anywhere in Sydney over the weekend during COVID-19 lockdowns will be met by "up to 1000 police".
The warning comes after major protests in the Sydney CBD last weekend saw dozens charged.
"Coming into town to protest is not the answer," Mick Fuller said.
"If you think you can splinter from that and protest somewhere else in Greater Sydney, that force will be mobile and will be waiting for you.

"You have been given plenty of warnings."
The stern message comes as New South Wales recorded 170 new coronavirus infections, with at least 42 of those infectious within the community.
He said the strike force investigating last week's protests had so far "locked up" 60 people and issued more than 200 infringement notices, and he expected that number to grow.
"If you turn up, you can expect the same sense of force," Commissioner Fuller said.
He said police had to "expect" a protest this weekend.

"Protesters are using chats and other forums, so it has been more complex to work out numbers, but it is a very similar type of intelligence summary to what we saw leading up to last week," he said.
"It appears it will not be in the same numbers."
He said it could still be "violent".
Close contacts, positive cases on notice
Commissioner Fuller said police and ADF personnel would be checking on more than 2000 premises where people have either tested positive to COVID-19 or have been identified as close contacts.
He cited the example of a man who tested positive to the virus but went to work this morning at a construction site.
A compliance check at the man's home revealed the breach this morning.
"That sort of behaviour is exactly why we need strong health orders, law enforcement and defence, getting the highest level of compliance," Commissioner Fuller said.
"One person could spread the virus. All the workers go home and spread it to their families so again, just one example of why we need to ensure is compliance checks."
'Don't give them a death sentence'
NSW Premier Gladys Berejiklian has pleaded with people to stay away from protests this weekend.
"It's going to prolong the pain for all of us," the Premier said.
"If you don't care about everybody else, surely care about your loved ones. Don't give them a death sentence.

"As we've seen, it's particularly affecting people who don't have any doses of the vaccines and were appealing to everybody, do the right thing but secondly, get vaccinated and get your loved ones vaccinated."
Positive COVID-19 case may have attended last protest
NSW Chief Health Officer Kerry Chant said it was possible somebody who had attended last weekend's protests had been infectious.
She said no documented cases of COVID-19 had been noted as having attended the protest, but that people could have not revealed their presence.
However, one positive case who "attempted" to attend developed COVID-19 afterwards.
"They did not know they had COVID," she said.
"If that person would have attended the protest, they would have been infectious.
"We're just working with police to ascertain whether that person did attend.
"The police did indicate they had turned the person around and they had given an infringement notice.
"We are working through that issue."
