Radical Bashir supporters ready for court

Radical cleric Abu Bakar Bashir's bid for freedom next week comes as terror fears reignite in Indonesia, but the current climate and his pledge to Islamic State may not factor into the case.

Bashir wants a judicial review of his 2011 conviction for supporting a terror training camp in Aceh, which has him serving 15 years' jail on central Java's Nusakambangan island.

It was there in July 2014 that he was photographed swearing his allegiance to IS, which his lawyers claim he has since retracted.

They have so far successfully had the proceedings sent to Cilacap - the small town closest to the prison island - from Jakarta, arguing the cleric is too infirm to travel.

Lawyer Achmad Michdan confirmed the 77-year-old will attend Cilacap District Court on Tuesday.

"Yes, definitely," he told AAP.

"The prosecutor ... could ask for more time.

"With that, we cannot examine witnesses and so I haven't summoned our witnesses."

Bashir was the spiritual leader of Jemaah Islamiyah, the group responsible for the 2002 Bali bombings that killed 202 people including 88 Australians.

He was sentenced to 26 months' jail in connection to the Bali attack, but was acquitted.

Taufik Andrie of the Institute for International Peace Building Foundation says Bashir's view of IS is unlikely to be a factor in this case, as it's a review of the Aceh matter.

The terrorism researcher says Bashir still has "huge influence" as a symbol.

"It's not really clear what he's aware of or if he has withdrawn from supporting ISIS," he told AAP.

"Around the last three to four months, he's no longer actively conveying it to the public, especially to the people visiting him in Nusakambangan.

"This doesn't show that he has totally changed though ... just that he's not being generous with his statements."

Bashir's release bid comes as terror fears have reignited in Indonesia.

Before Christmas, raids led by Australian, US and Singapore intelligence resulted in the arrest of network members who had allegedly discussed attacks on New Year celebrations and other targets.

The US government warned its citizens of a possible attack on the island of Lombok on New Years Eve.

Mr Andrie says he is less concerned about security around the trial than the capacity of judges outside the capital to handle a terror case.

"Not that I doubt local judges, but this serious and big case, with its vast magnitude ... it should be led by experienced judges," he said.
