Big Brother Australia is returning for 2025! Before you roll your eyes, it’s going to be closer to the Channel 10 original than… whatever it was Channel 7 was trying to achieve these last few years.
As announced at Paramount’s 2025 Upfronts presentation, Big Brother Australia 2025 will have live nominations and live evictions just like its glory days — and it will even have 24-hour live streaming. Plus, the production company behind the show, EndemolShine Australia, has potentially leaked the air date. Here’s everything we know about Big Brother Australia 2025!

When will Big Brother 2025 air?
Big Brother Australia 2025 is launching across Network 10 platforms in the last quarter of 2025, so it’s a little while off. A job advertisement shared by EndemolShine Australia, looking for Queensland-based Post Producers, Editors and Edit Assistants, gave a date range of early November to early December 2025. Seeing as this iteration is live-streaming, it’s likely we’ll get our first episode in November. We can’t wait!

Where will Big Brother 2025 be filmed?
Ten announced that Big Brother 2025 will have “a brand-new home”.
The original Big Brother Australia was filmed at Dreamworld on the Gold Coast, and the latest iteration was filmed at Sydney’s Olympic Park. In a new job advertisement for the show, the location has been confirmed to be Queensland.
Big Brother Australia has been on Channel 7 for the last few years with the network trialling a new challenge-style format. It has terrible ratings and was ultimately axed. The last season was Big Brother 2023.
Who is the Big Brother 2025 host?
Mel Tracina has been announced as the host of Big Brother Australia 2025.
“Mel is a self-confessed reality TV junkie who will bring so much energy and passion to this revitalised series,” Ten’s release read.
“With 24-hour live streaming, live nominations and live evictions, viewers won’t dare miss a moment of the drama as it all unfolds in real time. Get ready Australia – Big Brother is watching.”
Big Brother Australia was first hosted by Gretel Killeen, then Kyle & Jackie O, then Sonia Kruger.
Who is in the cast?
The cast is yet to be announced but Ten has promised “relatable everyday Australians” and after what we’ve been getting from MAFS the past few seasons, I could not be more thrilled for some authenticity.
