"We have detected supporting funds from an Australian source to terrorist networks in Indonesia," deputy chairman of the Indonesian Financial Transactions Reports and Analysis Centre Agus Santoso said during an international conference on the Islamic State on Monday.
Indonesia tracked the transactions in cooperation with the Australian Transaction Reports and Analysis Centre (AUSTRAC). Its 2014 report on financing terrorism, states that most funds raised by terrorism supporters in Australia are transferred to militant groups abroad.
According to the Indonesian counterterrorism coordinating agency, more than 500 Indonesians have joined the Islamic State in Syria and Iraq. The International Centre for the Study of Radicalisation and Political Violence estimates that about 20,000 fighters from all over the globe have joined the group.
The Islamic State currently controls areas of Iraq and Syria. The group also operates offshoots across the Middle East and actively recruits members online.
