Australian and Indonesian authorities are investigating suspected Islamic State funding, with “significant” amounts of money raised in Australia and sent recently to Indonesia.

The funding was detected in a joint operation between Indonesia’s Financial Transactions and Analysis Centre (PPATK) and its Australian counterpart, the deputy chairman of PPATK, Agus Santoso, said yesterday.

Information about the Indo­nesian recipients — believed to be ­Islamic State-supporting groups although Mr Agus would not confirm that yesterday — has been handed to the national police counter-terrorism unit, Densus 88. PPATK officials would soon travel to Australia to continue their investigation with the Australian Transaction Reports and Analysis Centre, Austrac.

…A Singapore-based terrorism expert, Rohan Gunaratna, told Monday’s conference that he had identified 19 Islamic State support groups in Indonesia, compared with three in The Philippines and five in Malaysia.

He claimed Indonesia was hosting 200 radical Islamist websites, many spreading Islamic State propaganda and ideology.
