Australian Prime Minister Anthony Albanese apologised on Monday to the country's Jewish community over a mass shooting that targeted a Hanukkah event at Sydney's Bondi Beach just over a week ago, killing 15 people.

"As prime minister, I feel the weight of responsibility for an atrocity that happened whilst I'm prime minister, and I'm sorry for what the Jewish community and our nation as a whole has experienced," he said.

"The government will work every day to protect Jewish Australians, to protect the fundamental right as Australians that they have to be proud of who they are, to practise their faith, to educate their children and to engage in Australian society in the fullest way possible."

The apology came a day after Albanese was booed by an angry crowd gathered at the beach to honour victims of the gun attack and as the parliament of the country's New South Wales state was recalled for two days to vote on proposed new laws that would impose major curbs on firearms ownership, ban the display of terror symbols and restrict protests.

The new rules will cap the number of guns an individual can own to four, or 10 for exempted individuals like farmers. There are more than 1.1 million firearms in New South Wales, officials said.

Albanese's apology also came as documents filed by the police with the courts alleged that the father-and-son suspects blamed for the mass shooting had trained for the attack in the New South Wales countryside.

One of the alleged Bondi gunmen, Sajid Akram, 50, was shot dead by police and owned six firearms. His 24-year-old son Naveed Akram, who has been transferred to jail from hospital, has been ⁠charged with 59 offences, including murder and terrorism, according to police.

The two alleged gunmen had planned the attack for several months and threw bombs at the crowd though they did not detonate, Australian media reported, citing a police fact sheet released by a court.

Pictures were released showing the accused firing shotguns and moving in what authorities described as a "tactical manner".

The pair also recorded a video in October railing against "Zionists" while sitting in front of a flag of the Islamic State group and detailing their motivations for the attack, police said.

And they made a nighttime "reconnaissance" trip to Bondi Beach just days before the killings, the documents showed.

Albanese said on Monday he would push for tough new laws creating "an aggravated offence for hate preaching".

"We're not going to let the ISIS inspired terrorists win. We won't let them divide our society, and we'll get through this together," he said. (Agencies)
