Everything We Know About Big Brother Australia 2025
We're heading back to the diary room. Big Brother Australia first began in 2001, but the reality TV juggernaut has seen many iterations over the years. From Big Brother VIP with MAFS' Jessika Power, Ellie Gonsalves and Caitlin Jenner, to Big Brother: Royalty v New Blood bringing back OG stars Tully Smyth and Anthony Drew, the format has gone through multiple overhauls.
The original version was a more observant reality TV show, with 24/7 live streams and Australia being allowed to participate in eviction voting. Channel Seven drastically changed Big Brother, letting contestants evict each other, and even turned it into a faux Love Island during Big Brother: House of Love. However, Big Brother has returned to Channel 10 for 2025, and the network has promised a complete return to the original format, including live evictions and live nominations.

"Dreamworld is nostalgic and authentic to the original Big Brother roots, there is honestly no better home for the Big Brother house."
