The Islamic State group is working to boost its presence in Indonesia with dreams of creating a “distant caliphate” in the world’s most populous Muslim-majority country, Australia warned on Tuesday.

Attorney-General George Brandis, who spent in meetings between Indonesian and Australian ministers, police chiefs and security officials, said it constituted a threat to Australian and Western interests.

“ISIS has ambitions to elevate its presence and level of activity in Indonesia, either directly or through surrogates,” he told The Australian newspaper, referring to the jihadist group by another acronym.

“You’ve heard the expression the ‘distant caliphate’ “ISIS has a declared intention to establish caliphates beyond the Middle East, provincial caliphates in effect. It has identified Indonesia as a location of its ambitions.”

Islamic State, which adheres to a fundamentalist doctrine of Sunni Islam, has already declared caliphates in several areas outside Syria and northern Iraq where it holds a swathe of territory.

Brandis’ comments follow Indonesian police foiling plans for a suicide attack in Jakarta and arresting radicals linked to Islamic State.

Three-day raids across Java ending Sunday saw the confiscation of explosive materials and an IS-inspired flag as well as nine arrests.

The extremists were targeting shopping malls, police stations and minority groups across the country, Indonesia’s national police chief said.

Security has been beefed up across the country, with senior ministers from Australia and Indonesia agreeing yesterday to boost intelligence sharing, including on terrorism financing, following bilateral talks in both Sydney and Jakarta.

The Australian newspaper said that while Australian authorities believed there was little chance IS could create a caliphate within Indonesia, they were deeply worried the terror group may establish a permanent foothold in the archipelago.

This could allow it to conduct attacks against Western or Australian interests within Indonesia and beyond. Justice Minister Michael Keenan said the rise of jihadist groups had destabilised the security of both countries. “The rise of ISIS in the Middle East is something that has destabilised the security of Australia, it’s destabilised the security of Indonesia and it’s destabilising the security of our friends and partners, particularly here in the region,” he said.
