Housemates Already Inside
Jane
Jane, a 67-year-old retiree, was the first housemate voted into the Big Brother house. If she joins, she will be the oldest ever participant in Australian Big Brother history.
“I’m a grandmother but not your average grandmother. My suitcase has no tracksuits, it’s all sparkle, heels, bikinis. I’m going to talk some shit, I’m going to tell some lies. And now I’m single, you better watch out!”
Colin
Colin is a lively 21-year-old from Wollongong, New South Wales. He calls himself a “mama’s boy” and aims to take his mum to Egypt if he wins, fueled by his passion for conspiracy theories.
These are just two of the diverse personalities shaping this dynamic Big Brother season.
Summary
Big Brother Australia 2025 promises thrilling live moments and diverse contestants, with the added excitement of viewers voting in one final housemate.
