Senior Director at the Counter-Extremism Project Dr Hans-Jakob Schindler told 9News.com.au the terror group has not yet regained its 2002-era prominence.
"There has been a steady trickle of terrorist incidents for which JI is reported to be responsible," Dr Schindler said.
"While JI of old was attacking primarily government and security forces as well as Western targets, some of the newer JI networks seem to have learned a lesson from ISIS and are now also targeting religious and ethnic minorities in Indonesia in an apparent attempt to cause societal discord."
