Thank you, Steve.

Well, I'm standing next to a makeshift memorial not far from where Sunday's attack happened.

And it's a cool Tuesday evening here.

And around me, there is a sea of hundreds who have come to pay their respects to the victims.

I've been watching as people slowly and respectfully make their way through the small streets approaching Bondi Beach, many carrying flowers.

And they're from all walks of life of all ages, members of the Jewish community, but also the wider Australian community.

And there's a very serene feeling here with the sound of the waves in the background.

But there's also a heavy police presence.

And I've been hearing police car sirens and seeing flashing lights and the heavy roadblocks in the background.

And it's all just a reminder of the tragedy that happened not very far from here, only 48 hours ago.

There have been some significant developments in the investigation.

Yes, New South Wales police have said that improvised explosive devices and two what they called homemade Islamic State flags were found in a car linked to one of the men, the son who is currently in hospital in police custody.

His father was shot dead by police on Sunday.

They also said the counter-terrorism investigation would now look at why the two men visited the Philippines last month and the places they may have traveled to.

Now, the Philippines Immigration Bureau has told NPR that the men arrived in the country together in early November and reported their final destination as Davao on the southern island of Mindanao.

It says they left the country in late November.

The Bureau has identified the father as an Indian national and a resident of Australia.

The son is an Australian citizen.

And Australian authorities have reiterated that at this point, though, there's no evidence that other people were involved in the attack.

We've seen Prime Minister Anthony Albanese, together with state and territory leaders, commit to immediate action to tighten Australia's gun laws.
