Meet the Big Brother Australia Housemates for 2025

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."

From a social worker to a self-described "openly fat, Black lesbian" and a single dad, the cast of Big Brother Australia 2025 are set to entertain the country as they compete for a $100,000 prize. Below, we've rounded up everything we know about the Big Brother Australia housemates for 2025.

Emily is a primary school teacher who has a big heart with a soft spot for Scotch Fingers. The housemate admits she's a germophobe and hypochondriac, so it will be interesting to see how she deals with a messy Big Brother house.

Also from WA, Holly is a 31-year-old model who calls herself a "unicorn". She has over 103,000 followers on Instagram, and previously dated Luxe Listings Sydney's Gavin Rubinstein. "[I'm] full of life, full of energy... you guys can expect a whole lot of entertainment," Holly declares.

Allana is a social worker and mother who loves to drink gin by the beach. She's prepared to call out bad behaviour while always speaking the truth.

Bruce comes from a small town in Queensland, so he's hoping that Big Brother Australia will help him step into the limelight. The tradie hopes to be married with one child by the time he's 30, and wants his wife to be a "trad wife", or stay-at-home mum.

Disability Advocate Conor has Tourette's Syndrome, and the educator wants to educate and inspire Australia. He survived a hit-and-run at 18 years old, and wants to turn "stigma into strength".

Mama's boy Colin is an aspiring MMA fighter from Wollongong, who is apparently "allergic to making his bed". He believes his social skills are his "super power" and has plans to stir the pot.

Single mum of three, Coco, has been through the ringer. Coco has survived two tumours, chest surgery and losing her dad. She leaves behind a broken marriage and 11 years working in early education to join Big Brother Australia, and had an instant bond with Holly.

Michael is a publisher hailing from Sydney's Eastern Suburbs. The single dad ruffled some feathers when he proudly announced that he hated "woke people" and "cyclists on the footpath", so his strong opinions will be sure to create drama in the house.

Sales manager Edward is a typical Aussie bloke... except he's never had a girlfriend. Could he be looking for love in the Big Brother Australia house? As the youngest of six, he's used to chaos and a full house — something he can use to his advantage. He wants to prove that nice guys don't finish last, and hopes to play with kindness.

Musician Abiola is here to shake things up. Neat-freak Abiola says she wants to be "the first openly fat, Black lesbian on TV", and plans to be unapologetic and honest. Her name means "born to be famous", so she's definitely one to watch.

Mia left her job as a retail assistant at Bunnings to bring her infectious energy to Big Brother Australia. The South Asian woman is here to push for inclusivity and representation, but she isn't afraid to get her hands dirty — she will plot revenge when necessary.

Vincent comes from regional Victoria, and is very in tune with his Italian heritage. He says he grew up making passata, salami and wine with his Nonno, before moving out at age 18. He works as a barber, so perhaps he can give some of the other housemates a fresh cut when they need one!

There will be a 13th housemate added on Big Brother Australia: 67-year-old retiree, Jane, or 36-year-old Mitch. Viewers have been given the chance to vote on who they want to send into the house, and all will be revealed during the next episode.
