They're champions in their own right after having successful careers in sport, and now two well-known faces from Sutherland Shire are on a mission to be champion survivors.
Marathon swimmer Susie Maroney and Cronulla Sharks legend Andrew Ettingshausen join the cast of the next instalment of Australian Survivor on Network 10.
Australian Survivor: Champions Vs Contenders' is set to be a showdown, with experience battling it out against fresh blood.
Strategies, secret immunity idols and gut-churning dishes will be served up in the upcoming season.
Contenders will fight for glory against a tropical backdrop in Fiji.
Maroney, 44, is the most highly decorated long-distance swimmer in Australian history, showing her prowess in 1999 when she swam from Mexico to Cuba at a total distance of 200 kilometres in 38 hours - the world's longest open water swim that no one else has replicated since.
She hopes to follow in the footsteps of Olympic swimmer Shane Gould who took out the title of Sole Survivor last year.
