Australia's royal commission into antisemitism, prompted after the Bondi Beach shootings that killed 15 people and injured 40, has begun public hearings.

The federal commission - the country's most powerful form of public inquiry - will investigate the prevalence and key drivers of antisemitism and make recommendations to government.

Headed by former High Court Justice Virginia Bell, the inquiry - which started on Tuesday - will also examine the events leading up to the attack, which was Australia's worst mass shooting in decades.

Prime Minister Anthony Albanese had resisted calls for a federal inquiry, saying it would hinder social cohesion but later bowed to public pressure.

"I acknowledge the importance of addressing antisemitism within the Australian community," Bell said in a statement last week.
