Big Brother Australia has returned to its roots in 2025, with live nominations, live eliminations and a 24/7 live stream.
The casting team has also taken a different route from the most recent season, which was littered with single 20-somethings not opposed to striking up a romance. Instead, this season’s cast is a varied bunch, with ages ranging from 21 to 67, and includes an MMA fighter, a disability advocate, and a social worker.
On the premiere night of Big Brother 2025, host Mel Tracina introduced 12 housemates to Australia and then tasked them with voting for the 13th, who would enter the house the following night. Grandma of four, Jane or 36-year-old straight-shooting Mitch. Jane was chosen by the country, but whether it’s the last we’ll see of Mitch, we’ll just have to wait and see.
Meet the Big Brother Australia 2025 housemates.
Abiola, 24, VIC
Abiola is a loud, proud and unapologetic muso who lights up every room she walks into. She’s funny, fearless and proudly gay, and with a name that literally means “born to be famous,” she’s sure to make her mark on the house.
Allana, 45, QLD
Allana is a fiery, funny and straight-talking mum of three who always keeps it real. As a social worker, she knows the importance of keeping a balance between work and fun, which for her, usually involves belting out tunes with a gin in hand.
Bruce, 25, QLD
Bruce is a cheeky tradie who loves being the centre of attention and isn’t opposed to a bit of drama. He’s a self-proclaimed traditional guy with strong opinions about relationships, which is bound to ruffle a few feathers inside the house.
Coco, 30, NSW
Coco is a straight-talking single mum who’s been through it all and still manages to light up a room. She’s survived two tumours, chest surgery, and the heartbreak of losing her dad and has the kind of resilience that makes you instantly root for her.
Colin, 21, NSW
Colin is the loveable troublemaker from Wollongong who can talk anyone’s ear off and turn any moment into a laugh. He’s loud, charming and always up for fun, but has a big heart underneath it all.
Conor, 31, QLD
Conor is a disability advocate and proud larrikin who turns every challenge into an opportunity to connect. Living with Tourette’s, his goal is to educate, entertain and show Australia the real face of the condition.
Edward, 31, SA
Edward is the laidback nice guy who loves a good laugh and has a soft spot for anyone doing it tough. He’s the kind of guy who can crack a joke, and give great advice, but he’s never had a girlfriend — will he find love on Big Brother?
Emily, 30, WA
Emily is a quirky, emotional and endlessly endearing teacher who wears her heart on her sleeve. She’s the type to cry at a cartoon, overthink every conversation and still win everyone over with her warmth and humour.
Holly, 31, WA
Holly is a cat-loving model who’s equal parts glamour and chaos. She’s travelled the world, learned not to take herself too seriously and knows exactly how to read a room, and is out to prove her intelligence to Australia.
Jane, 67, Victoria
Jane entered the house on the second night as the 13th cast member. She’s a straight-talking grandmother who’s bringing life experience, humour and a touch of old-school grit to the house. She’s not afraid to call things as she sees them and is ready to prove that age doesn’t hold anyone back.
Mia, 23, VIC
Mia is the unapologetic firecracker with a contagious laugh and zero time for fake people. She’s loyal, outspoken and not afraid to cause a bit of chaos if it means standing up for herself or her friends.
Michael, 49, NSW
Michael is a confident single dad who’s funny, opinionated and never afraid to speak his mind. He’s all about real connections and keeping things authentic, but if someone crosses a line, they’ll definitely know about it.
Vincent, 21, VIC
Vincent is a smooth-talking Italian barber who knows how to charm a crowd and turn heads while he’s at it. He’s confident, cheeky and full of charisma, but underneath it all is a guy who values family, loyalty and a good laugh.
