Five IS terrorists have been stripped of their Australian citizenships and will never be allowed back into the country.
Home Affairs Minister Peter Dutton says the five dual-nationals had turned their backs on Australia by becoming involved with terror organisation in the Middle East.
"Cessation of Australian citizenship for dual nationals involved in terrorism is a key part of Australia's response to international violent extremism and terrorism," Mr Dutton said on Thursday.
"The government is determined to deal with foreign terrorist fighters as far from our shores as possible to ensure that if they do return it is with forewarning and into the hands of authorities.
"These five dual nationals have been acting against Australia’s interests by engaging with terrorism and have effectively chosen to leave the Australian community."
