In a post on social network X, New South Wales police announced: "The police campaign is still ongoing and we continue to urge people to stay away from this area."
Local media reported many injuries, while international TV stations broadcast images showing many people lying on the ground.
I saw at least 10 people lying on the ground with blood everywhere, Harry Wilson, 30, a local resident who witnessed the incident, recounted.
Mr. Alex Ryvchin, co-chair of the Australian Council for the Israel Commission, said that the shooting occurred at a beach event to celebrate the Israeli Hanukkah festival, which began at sunset.
This is the time for the Israeli community to gather together to mark a happy occasion. If we were really targeted in this way, it was something that none of us could have imagined. This is a terrible tragedy, Ryvchin said, adding that his media advisor was injured in the attack.

The chaotic atmosphere was clearly felt in videos circulating on social network X, a series of people on Bondi Beach ran away amid the sound of gunshots and police car horns.
Another video recorded two men being controlled by the police, lying face down on a small pedestrian bridge. The officers were seen trying to revive the victims.
We have received information about a security situation going on at Bondi. We call on people in the surrounding area to follow the instructions of the New South Wales State Police, said Australian Prime Minister Anthony Albanese.
According to the latest information, local police confirmed that the shooting killed 10 people. The scene was temporarily safe after the two suspects were arrested.
