Rise in Aust jihadists on Turkey's list

The number of suspected Australian jihadists believed to be headed to Syria and Iraq on Turkey's "no entry" list has grown to about 420.

There was just 90 in 2014 but more have been added since, a Turkish official told the ABC - with 21 suspected Australian foreign fighters deported over the past two years.

Justice Minister Michael Keenan refused to comment on details of the list, but told ABC radio on Thursday "if (the Turks) can stop any Australian from going to the conflict zone then that is obviously a good thing".
