In December 2015 the Director General of ASIO Duncan Lewis stated that the number of Australians seeking to travel overseas to fight with groups such as ISIS had "plateaued a bit" due to better awareness of the issue among the Islamic community, few young Australians being attracted to ISIS and improvements to the speed with which passports could be cancelled. He also stated that a "tiny, tiny" proportion of Australian Muslims were influenced by ISIS. At this time the government believed there were around 110 Australians fighting with extremist groups, which was slightly lower than previous levels, and 44 Australians had been killed in Syria.
