An Islamist web site, www.islamic-minbar.com, posted a statement by Jemaah Islamiyah saying: We decided to settle accounts with Australia, one of the worst enemies of God and Islam, ... and a Mujahadeen brother succeeded in carrying out a martyr operation with a car bomb against the Australian embassy...

It described the events leading up the attack; On 5 August, at Noordin’s instructions, Rois set off to retrieve Heri Golun, who had been selected as the suicide bomber, and buy the Daihatsu vehicle that was used in the bombing.

From then until 17 August, frantic activity moving the principals, purchasing additional materials for the bombs and raising funds – alternated with lulls, when the operatives went to Internet cafes to pass the time.

When Heri said he was ready, he moved into the house where Noordin and Azhari were and slept in their room at night, so they could give him additional religious counselling.

On 23 August, Rois started to teach Heri Golun how to drive, and on 9 September, the new driver blew himself in front of the Australian embassy.In March 2005, Irun Hidayat was charged with being an accessory by giving money to one of the bombing's perpetrators and providing housing after the attack for Azahari and Noordin.

[15] On 21 July, he was convicted of being an accessory by providing a house to Azahari and Noordin, but not to having planned the September attack, and was sentenced to three years in jail.

He helped one of the core bombers, "Rios", scout for safe houses and transported around 70 kilograms of highly explosive TNT.
