A Jewish security agency warned that the security alert level was “high” ahead of the Bondi Beach shooting, a landmark royal commission has found.

The commission – Australia’s most powerful form of public inquiry – was announced in January, three weeks after two gunmen opened fire at an event marking Hanukkah at Bondi Beach, killing 15 people.

The interim report by former High Court judge Virginia Bell also gave 14 recommendations including prioritisation of gun reforms and extending the policing arrangements for Jewish high holy days to other Jewish events as well.

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.

Sajid Akram, 50, was killed by police at the scene of the shootings and his son Naveed Akram – the other alleged attacker – was critically injured and later transferred from hospital to prison.

The 24-year-old has been charged with 59 offences, including 15 counts of murder and one of committing a terrorist attack.

Thursday’s report noted an email sent to New South Wales (NSW) Police by Jewish security group CSG NSW on 8 December advising them of upcoming Jewish events and requesting policing measures.

The email said that the current security alert level for the Jewish community was “‘HIGH. A terrorist attack against the NSW Jewish Community is likely and there is a high level of antisemitic vilification”, according to the report.

NSW Police acknowledged “a request for police presence at these events” but said it had “received no specific request for dedicated police resources” for the Hanukkah event, according to the report.

Differences between the information provided by NSW Police and CSG NSW “cannot be resolved on the information presently available to the Commission,” it continued.

The report also recommended that state and federal governments should prioritise efforts to finalise and implement “nationally consistent” firearms reforms as well as a proposed gun buyback scheme.

Gun reforms put forward in the wake of the shooting have received a lukewarm response from some of Australia’s states and territories, with Queensland, for example, refusing the buyback scheme and a cap on firearms ownership.

The report also said NSW police procedures used for Jewish high holy days should be extended to other “high risk Jewish festivals and events, especially those with a public facing element”.

Other recommendations included a review of joint counter-terrorism teams in Australia – made up of federal and state police forces, and the Australian Security Intelligence Organisation (ASIO) – as well as making the counter-terrorism commissioner’s role full time.

Five recommendations remain confidential due to national security concerns.

The prime minister and national cabinet ministers should also take part in counter-terrorism exercises within nine months of each federal election, the report said.

The report said that it had not identified any gap in existing legal frameworks that would have prevented the attack, or impeded the ability of law enforcement or other agencies to respond to it.

“In these respects, no issue requiring urgent or immediate action has been identified,” the report said.

It added that any failures to identify and act upon intelligence in the lead up to the shooting and in the allocation of police to the Hanukkah festival would be addressed in hearings, though some of these may be closed to the public.

Albanese said the report showed “no urgent changes” were required but that governments “could always do better”.

After the report was released local rabbi Yossi Friedman told the BBC that many people in the “tight-knit” Jewish community were still struggling in the aftermath of the attack and were living with the “real feeling that this could happen again”.

“While the [report’s] findings are so important… even more important is not just what happened on the night but how did we get here, how did we allow a surge in antisemitism and violent activity to take place against a segment of the population,” he said.

David Ossip, President of the NSW Jewish Board of Deputies, said the report was “an important first step” in examining the circumstances around the attack but that it was “only part of the picture”.

Antisemitism was “not only a law enforcement issue” but a “societal issue” and “the environment for Jewish Australians had been deteriorating well before Bondi”, he said.

Alex Ryvchin, of the Executive Council of Australian Jewry, told the ABC there were still “burning questions” surrounding the attack including how the Akrams were able to acquire firearms and why the festival hadn’t been better resourced by police.

A first series of public hearings for the inquiry, which is looking at the rise of antisemitism in society and institutions and the events leading up to the mass shooting, is to begin on Monday.

A final report is to be delivered on the anniversary of the shooting.

Bell has previously warned that the scope of the evidence that the inquiry can look at will be limited given the current court proceedings for Naveed Akram.
