CANBERRA - AUSTRALIA has urged its citizens to rethink travel to Indonesia, saying the threat of a terrorist attack is high as the country prepares to execute three militants over the 2002 Bali bombings.

The convicts - Imam Samudra, Amrozi Nurhasyim and Ali Ghufron - have 'exhausted their legal options' to avoid their death sentences, which will be carried out next month, Mr Jasman Panjaitan, a spokesman for Indonesia's Attorney General, told reporters on Friday.

Australia's Department of Foreign Affairs and Trade updated its travel advice for Indonesia late Friday to include news of the impending executions of the bombers, who killed 202 people, including 88 Australians, on the tourist island of Bali in 2002.

The department left Indonesia's risk rating unchanged at level four on a scale of five. The strongest warning is reserved for violence-wracked countries rated as a five, including Iraq and Afghanistan.

'The Indonesian government announced on Oct. 24 that the three individuals convicted for involvement in the 2002 Bali bombing would be executed in early November,' the department Web site said.

'We advise you to reconsider your need to travel to Indonesia, including Bali, at this time due to the very high threat of terrorist attack.'

Indonesian authorities have also said they fear the executions could provoke reprisal attacks.

The Bali attacks - allegedly funded by Al-Qaeda - were carried out by members and associates of Jemaah Islamiyah, a Southeast Asian militant group blamed for at least three other suicide bombings in Indonesia, including attacks on the J.W. Marriott hotel and the Australian Embassy in Jakarta.

The last bombings occurred in 2005, killing 21 people in multiple blasts in Bali cafes and restaurants. -- AFP
