Five terrorists who travelled overseas to fight with Islamic State have been stripped of their Australian citizenship and will never be allowed back into the country.

Home Affairs Minister Peter Dutton said the five dual-nationals had turned their backs on Australia by joining the notorious terrorist group in the Middle East.

"I don't want these people coming back, I want them to stay as far from our shores as possible," Mr Dutton told 2GB radio on Thursday.

"Our country is safer because these people aren't returning."
