The Traitors Australia is returning in 2026 for a third season after several years away from Australian screens, but the revived series will look a little different.
Like former seasons, season three is stacked with iconic reality television personalities, with the 2026 cast including The Bachelor legends Keira Maguire and Alex Nation, Married at First Sight fave Cam Merchant and former Big Brother housemate Tully Smyth.
However, Gretel Killeen is replacing Rodger Corser as host and the production has moved away from its original New South Wales home. The Traitors Australia has gone international!
The new location provides a suitably spooky and isolated backdrop needed for secret meetings, dramatic banishments and the ongoing battle between the Faithful and the Traitors.
Where was The Traitors Australia filmed?
Season three of The Traitors Australia was filmed at Castle Claremont, near Timaru on New Zealand’s South Island. The property is literally located at 222 Mount Horrible Road (not kidding!), which can be found approximately 15 minutes from central Timaru.
The Neo-Gothic mansion sits within around 11 hectares of stunning landscaped grounds. The sprawling home contains 10 bedrooms, five bathrooms, a formal dining room, a library and billiard room, reception areas and a chapel, giving producers plenty of atmospheric spaces for the show’s challenges and confrontations.
The historic homestead has a twisted history, too. It was originally constructed for prominent Canterbury pastoralist George Hampton Rhodes and his family during the late 1880s, but it was later owned by the Catholic Church and used as a Marist Brothers novitiate before eventually becoming a boutique accommodation and events venue.
The Traitors Australia contestant from Real Housewives of Sydney, Krissy Marsh, boasted about the historical filming location. “My first impression when I arrived at the manor was just how grand it was,” she told Home Beautiful. “It felt like a place that had witnessed generations of stories before we ever stepped through its doors.”
Castle Claremont has also been used by The Traitors New Zealand, allowing the Australian and New Zealand productions to share a location, props and similar challenges.
When was The Traitors Australia filmed?
Season three was reportedly filmed way back in September and October of 2025, almost a year before its scheduled Australian premiere in August 2026.
The celebrity cast was revealed shortly after filming finished, although Network 10 has not publicly confirmed exactly when production began and ended.
The relatively short filming period is consistent with The Traitors format, which typically places contestants inside an intense, tightly controlled game stretched over just a few chaotic weeks.
Where were the previous seasons of The Traitors Australia filmed?
The first two seasons were filmed at The Robertson Hotel in Robertson, which is in the Southern Highlands of New South Wales. The hotel itself confirmed that both the 2022 and 2023 seasons used its grand interiors and surrounding grounds for filming.
Built in 1924, the heritage property has 55 rooms and suites, along with restaurants, function spaces, lounges and sprawling gardens.
Its old-world design helped establish the dark murder-mystery atmosphere of the original series. However, for the 2026 revival, production shifted across the Tasman to Castle Claremont, giving season three a brand new look and feel. Bring on the murder, we say!
The third season of Traitors Australia premieres on Network 10 and 10Play on August 4, 2026.
