But for some, this is all too late.

Among those who've already assigned blame for the shooting is the Israeli Prime Minister, Benjamin Netanyahu.

He said he'd written to his Australian counterpart in August, telling Anthony Albanese that recognising a Palestinian state would encourage anti-Semitism.

He claimed the Bondi Beach shooting was a consequence of that decision.

And there were similar sentiments expressed by Levi Wolfe, rabbi of the Central Synagogue in Sydney.

He too seemed to complain that the government had been too tolerant of prejudice.

Rabbi Wolff was also one of the many Australians who said they'd already taken precautions out of fear of an attack.

Schools, for example, discouraging pupils from wearing anything which identified them as Jewish.

And the Sydney-based journalist Amy Leibovitz said she had specifically avoided going to the Bondi Beach event out of fear of what might happen.

So could the attack have been predicted and indeed prevented?

My colleague Stephen Nolan has been discussing this issue with Dr Josh Roos.

He's a politics professor at Deakin University in the Australian state of Victoria and says threats against Jews have been growing.

and from different sources.

And you mentioned that the Australian government hasn't done enough.

What more should they have done before now?

Dr John Roos.

In the aftermath of the attack, police have provided more information about the shooters.

The father was foreign-born and arrived in Australia in 1998 on a student visa.

He legally owned several guns and was a member of a shooting club.

He died at the scene.
