Australia will offer more help to South East Asian countries to prevent terror attacks across the region.
Prime Minister Malcolm Turnbull is set to discuss security with other leaders at the ASEAN summit in Laos.
Turnbull has signalled he would like to expand Australia's counter-terrorism arrangements with Indonesia, Malaysia and other neighbouring countries.
It comes after the so-called Islamic State threatened "lone wolf" attacks in Sydney and Melbourne.
Turnbull said that such a threat should be taken seriously after IS suffered losses on battlefields in Iraq and Syria.
