Not only will The Traitors Australia be returning to our screens with new host Gretel Killeen in 2026, but also with a new list of star-studded contestants.
The 2026 contestants include an impressive line-up of reality television stars from Survivor, Big Brother, MasterChef and so many more.

It was only last year fans were concerned the Channel 10 series would be facing the axe. But in October 2025, the network revealed a new host and new location!
“As a writer and performer, I love a new experience and hosting the new Traitors gives me permission to explore an alternate version of myself in an imaginary place, full of challenging mischief,” Gretel shared, who is taking the helm from Rodger Corser.
Now, the comedian is bringing her wit and sass to The Traitors season three, watching the contestants undertake any cunning moves and schemes to survive the social deduction game.
Some contestants will be marked as the Traitors, while others will be the Faithfuls. Traitors must remain undetected while turning the Faithful against themselves. But the Faithful must find the Traitors before it’s too late.
Below, The Weekly has revealed all the contestants joining The Traitors in 2026.
