Australia’s leader has said it is upsetting that Indonesia has further reduced the prison sentence of the bombmaker in the Bali terror attack that killed 202 people – meaning the terrorist could be freed within days if he is granted parole.

Australian Prime Minister Anthony Albanese said he had been told by Indonesian authorities that Umar Patek’s sentence had been reduced by another five months, taking his total reductions to almost two years.

That means Patek could be released on parole ahead of the 20th anniversary of the bombings in October.

“This will cause further distress to Australians who were the families of victims of the Bali bombings,” Mr Albanese told Channel 9.

“We lost 88 Australian lives in those bombings.”

Mr Albanese said he would continue making “diplomatic representations” to Indonesia about Patek’s sentence and a range of other issues, including Australians currently jailed in Indonesia.

He described Patek as “abhorrent”.

“His actions were the actions of a terrorist,” Mr Albanese told Channel 9.

“They did have such dreadful results for Australian families that are ongoing, the trauma which is there.”

Indonesia often grants sentence reductions to prisoners on major holidays such as the nation’s Independence Day, which was on Wednesday.

Patek received a five-month reduction on Independence Day for good behaviour and could walk free this month from Porong Prison in East Java province if he gets parole, said Zaeroji, who heads the provincial office for the Ministry of Law and Human Rights.

Zaeroji, who goes by a single name, said Patek had the same rights as other inmates and had fulfilled legal requirements to get sentence reductions.

“While in the prison, he behaved very well and he regrets his radical past which has harmed society and the country and he has also vowed to be a good citizen,” Zaeroji said.

Patek was arrested in Pakistan in 2011 and tried in Indonesia, where he was convicted in 2012.

He was originally sentenced to 20 years’ imprisonment.

With his time served plus sentence reductions, he became eligible for parole on August 14.

The decision from the Ministry of Law and Human Rights in Jakarta is still pending, Zaeroji said.

If refused parole, he could remain jailed until 2029.

Patek was one of several men implicated in the 2002 attack, which was widely blamed on Jemaah Islamiyah, a South East Asian militant group with ties to al Qaida.

Most of those killed in the bombing on the resort island were foreign tourists.

Another conspirator, Ali Imron, was sentenced to life.

Earlier this year, a third militant, Aris Sumarsono, whose real name is Arif Sunarso but is better known as Zulkarnaen, was sentenced to 15 years following his capture in 2020 after 18 years on the run.

Jan Laczynski, a survivor of the bombings, told Channel 9 that many Australians will be “devastated” by Patek’s potential release.

“This guy should not be going out unsupervised, unmonitored,” he said.
