Australia is offering a huge reward for information leading to the arrest and conviction of those behind the Bali nightclub bombing.
The government will give up to 2 million Australian dollars (€1.1m) to encourage people to come forward.
More than 180 people were killed by the weekend car bomb at Kuta Beach.
The terms of offering the reward will be discussed with authorities in Indonesia - where much of the information is expected to come from.
Authorities say 30 Australians have been confirmed dead, and about 140 remain unaccounted for.
The main suspect in the attack is the Southeast Asia-based militant Islamic group Jemaah Islamiyah, which is believed to have links to Osama bin Laden's al-Qaida network.
