Meet the 2026 Traitors Australia Cast:

Big Brother Australia
The Big Brother Australia alumni is very excited to join the show.
“Plot twist! 🕵🏼♀️ I’m joining the cast of The Traitors Australia, hosted by the one and only Big Brother legend, @gretelkilleen. 🗡️🥀
(KILLeen is a bit on the nose, even for me),” she wrote on Instagram.
“Think murder mystery meets trust issues meets… me trying to survive without oversharing. 🫣
“Am I a Faithful? Am I a Traitor? Am I just here for the snacks?
“If you know me, you know I love true crime, Cluedo, and a good old-fashioned whodunnit. So really… how could I say no?
“@thetraitorsau is a game of lies, loyalty, and late-night paranoia. Where friendships are tested and trust is optional. 🧐”
Rob Farnham
Musician and son of John Farnham
Rob traded Byron Bay for New Zealand to film the show, and cannot wait for others to see it.
“Was a pleasure to be apart of this. Made some cool new friends. Make sure you check out the show,” he wrote on Instagram.

Who is hosting The Traitors Australia?
After debuting in 2022, the Australian version of the beloved show was put on ice in 2023 following dismal ratings.
However, the former Big Brother Australia host, Gretel Killeen, will be taking over from Rodger Corser.
“The Traitors is returning to 10 in 2026 with Aussie legend @GretelKilleen as host! Dust off your cloaks, trusty Traitors, and prepare to bury the hatchet… in your closest ally’s back 🗡️🥀,” Channel 10 wrote in an announcement on September 28.
