A long way from his homeland, Neil Prakash is currently locked up in a maximum security Turkish prison near the Syrian border.
And if the Prime Minister has his way, the former Melbourne schoolboy turned alleged high-ranking IS operative, will be kept under lock and key for a long time to come.
Thought to have been killed in a US air strike last year, it turned out he was only injured and now the 25 year-old is wanted in countries around the globe over terrorism-related activities.
Malcolm Turnbull is pushing to get him back to Australia as soon as possible.
Under an arrest warrant issued by the Australian Federal Police, he faces life in jail for charges of fighting with terrorists in Syria and Iraq, being a member of an outlawed organisation and recruiting for a terror group.
Investigators have travelled to Turkey to speed up the extradition process and if Neil Prakash is returned to Australia, he is likely to face court in his birthplace, Melbourne.
Foreign affairs analyst Greg Barton says it sets the scene for potentially one of Australia's most significant international terrorism trials.
Greg Barton says it's important for Australian authorities to establish good relations with their Turkish counterparts, given many of the country's more seasoned counter-terrorism officials have been sidelined in the political fallout from last year's aborted coup.
The Prime Minister says there is no room for complacency when it comes to dealing with what he calls dangerous radicalised terrorists.
