Big Brother Australia is back, and the housemates are all larger-than-life characters. Host Mel Tracina welcomed 12 contestants into the house during Episode 1, and while there was plenty of rain at Dreamworld, spirits were high. So how did producers whittle down over 20,000 applications to find the perfect candidates for Big Brother Australia 2025? Tracina tells Refinery29 Australia that great care was taken to represent different types of Australians in the house. “The housemates that [have been] chosen for this season are such a great range of people that come from different walks of life and have different ways of thinking, and different morals and beliefs,” she says. “I believe that there will be conversation that is opened up. What that is, no one can predict, though, because it’ll be just so organic.”
