Itโs arguably the most physically and mentally demanding reality TV show on Australian screens, but SAS Australia is back for another year.
As for this yearโs celebrity recruits โ youโll probably recognise a few.
Last year, rugby player and former Bachelor Nick โHoney Badgerโ Cummins, comedian Merrick Watts and AFLW player Sabrina Frederick were the only three stars to complete the course so weโve seen how tough this show is.
Elite ex-Special Forces soldiers Ant Middleton, Mark โBillyโ Billingham, Jason โFoxyโ Fox, and Ollie Ollerton are all back for another season as the Directing Staff (DS), and on Monday, Channel Seven officially announced the 18 famous faces tackling the military course.
