The national security committee will meet on Monday after Prime Minister Malcolm Turnbull returns from the ASEAN meeting in Malaysia, the first gathering since the terror attacks on Paris last weekend.
"I can assure you ... I have remained in the closest possible contact on all of these national security issues at home," Mr Turnbull told reporters in Kuala Lumpur on Sunday after attending a series of international meetings across the globe in the past week.
