SAS Australia will see stars attempt to pass the selection process to join the Australian Army’s elite Special Air Service.

The reality TV stars, models, athletes and radio personalities will receive no special treatment by their commanding officers.

Each celebrity will be referred to by a number on the show, and not by their name.

If the challenges ever get too much for the celebrities, they have the ability to quit by handing over their armband with their assigned number. 

The former special forces instructors can also choose to dismiss a celebrity recruit at any time if they deem them incapable of continuing on with the challenges.
