The orphaned children of notorious Islamic State terrorist Khaled Sharrouf could soon be granted travel documents to return to Australia after a plea for help was sent to the Australian Government.

Prime Minister Scott Morrison said he would not put lives at risk to extract them from the Syrian conflict zone, but if they can get to an Australian embassy they will likely be given passports to return.

"When they might be in a position to return to Australia, we will cooperate with that process," the Prime Minister told reporters in Canberra on Friday.
