Three people have been arrested following a pro-Palestine march last Monday, as police prepare for another march this weekend.
Police made the arrests following an investigation after flares had been set off during the protest outside the Opera House. An Israeli flag was also set on fire, and antisemitic chants were heard.
Eight others were charged over different incidents that took place since the rally.
Between 800-850 police will attend tomorrow's protest at Sydney Town Hall after working with march organisers to ensure a peaceful event.
"We expect good behaviour from participants, but if there is anyone that thinks that they can... cause trouble, police will be there to arrest [them]," NSW Police Commissioner Karen Webb said today.
"We have no tolerance for hate speech. No tolerance for intimidation during the protest activity [or] from anyone else who happens to be in the CBD tomorrow," Webb said.
A world divided: Global protests for Israel and Palestine
Police confirmed a form 1 had been submitted on time by the organisers and discussions had been made about the route of the march.
The Sydney Opera House rally had not been approved by police.
Officers are expecting up to 17 protests and gatherings related to the Hamas-Israel conflict over the next seven days in the Sydney Metropolitan and regional areas.
"We greatly respect the right of people to be able to voice their opinions in public assembly is something that is lawful," Metropolitan Field Operations Deputy Commissioner Mal Lanyon said.
"But it is something that we ask that people do peacefully... should people commit crimes, they can expect that they will be arrested and put before a court.
"We know that there is heightened tension within the community at the moment arising from the conflict from overseas.
"We will work with the community as we have done regularly."
