A landmark royal commission into antisemitism, called in the aftermath of the Bondi shooting, has recommended that gun reforms be prioritised and policing arrangements for Jewish holidays extended to other Jewish festivals.

The commission - Australia's most powerful form of public inquiry - was announced in January, three weeks after two gunmen opened fire at a Jewish event at Bondi Beach, killing 15 people.

The interim report by former High Court judge Virginia Bell gave 14 recommendations although five of them remain confidential due to national security concerns.

Prime Minister Anthony Albanese said a National Security Committee meeting had agreed to implement all of Bell's recommendations.

On 14 December last year, a father-and-son duo - armed with rifles and shotguns - targeted a Sunday afternoon event at a Bondi Beach park.
