Police concede they should have conducted a threat assessment of Hanukkah events after a Jewish security group warned terrorist attacks were likely.
As a royal commission probed the actions of intelligence agencies and police in the lead-up to the Bondi massacre on December 14, NSW Police's terrorism head accepted they should have assessed the major Jewish celebration after security body CSG pled with them to ensure community safety.
The inquiry was earlier told there was no evidence any intelligence agency suspected a terror attack would take place before 15 people were killed in the anti-Semitic shootings.
But ASIO identified Jewish holy events as attractive targets for terrorists months before the Hanukkah tragedy.
NSW Police Assistant Commissioner Leanne McCusker, who commands the counter-terrorism squad, said threats to the Jewish community were concerning in the months before the attack.
