Big Brother Australia has finally kicked off for 2025!
This year’s contestants are eager to cement themselves in the reality television hall of fame and win the life-changing $100,000 prize that comes with being the final housemate standing.
The beloved reality TV franchise returned to its roots at Channel 10 following a three-year hiatus from Aussie screens, and two controversial stints on Channel Nine and the Seven Network that failed to capture the essence of what originally made the show so popular in the early 2000s.
New host Mel Tracina introduced the new housemates during the premiere, and season 16 is sure to be reminiscent of the early noughties format of Big Brother that we all know and love so much (especially with Mike Goldman back again as the voice of Big Brother!).
With the return of live nominations, live evictions, and a 24/7 live stream for fans to watch, the fiery housemates are set to bring more drama than ever on the newly rebooted show.
Scroll on to meet the full cast.
Who are the Big Brother Australia 2025 housemates?
Jane, 67
After the first 12 Aussies went onto the show, it was up to Australia to vote in the 13th housemate.
It was between Jane and Mitch, with “feisty” Jane ultimately receiving the popular vote and entering the house!
She is the oldest contestant in show history and brings a lifetime of experience to the show.
Jane is a single mother of two boys and a proud grandmother to four grandsons.
Loyal and funny, she’s determined to win! She also recently got dumped and cheekily asked if Big Brother is single, and promised to make viewers laugh.
Also a lover of golf, she is a straight shooter and prefers to address problems face-to-face.
According to Paramount, she is also an avid Donald Trump supporter, but doesn’t plan to broadcast her political beliefs with her housemates.
Colin, 21
Self-confessed muma’s boy and MMA fighter Colin was the first housemate to enter the Big Brother house.
He described his mother as a “good bloke” and said being social is his superpower.
“I promise not to snake anyone in the house,” he vowed.
Allana, 45
Allana is bringing the energy to the Big Brother house, leaving her three children behind to enter the world of reality TV.
She admitted she will probably do something “cringeworthy” during her time on the show as she debuted her bubbly personality.
“I’ll be a unique housemate, I’ll bring energy to the house, but I won’t demand attention,” she promised.
Coco, 30
“True Aussie girl” Coco will be bringing her “razor-sharp” wit and “raw honesty” to the competition.
The single mother-of-three has survived two tumours, chest surgery, and the devastating death of her father.
“I’m bold, I’m bubbly, with a little side of bogan,” she admitted.
Conor, 31
Conor is a disability advocate who lives with Tourette syndrome.
He said living with Tourette’s means he is always being watched and described it as being similar to being in the Big Brother house, promising he will be the most “authentic” housemate yet.
“I’m basically a human golden retriever, I’m happy and bubbly, and I’m always looking for what makes other people tick,” he quipped.
Abiola, 24
Musician Abiola is a self-proclaimed clean freak who will be putting herself to the test in the iconic house.
She revealed her name means “born to be famous” as she made her reality TV debut in the hopes of winning the $100,000 prize money.
“In the Big Brother House, all I can be is myself. You can expect to see a fat, black, lesbian, that’s me, baby,” she said.
Vinnie, 21
Though he’s only 21 years old, Vinnie said he is a bit of an old soul – as well as a flirt.
The cheeky barber plans to make his housemates feel like his “family” and said he hopes to be the person others can confide in.
He admitted his plan is to make everyone fall in love with him, but added, “My word means everything on the outside of the house, but this is a game…”
Emily, 30
Chatterbox Emily wants to be a “mother hen” in the house and describes herself as a “lover, not a fighter”.
The primary school teacher admitted she sometimes overshares information she shouldn’t, as she looks set to shake things up among the cast.
“I’m most proud of marrying my high school sweetheart and having a really strong moral compass,” she added.
Bruce, 25
Tradie Bruce is saved in many girls’ phones as “trouble”, so he looks set to ignite some drama in the house.
“I’m bad news in the best way, let’s just say there won’t be a quiet moment when I’m in the house,” he promised.
He also shared his strong opinions on gender roles, admitting he believes men should take on the provider role in a relationship.
Holly, 30
Holly introduced herself as a bit of a “unicorn” and is a proud mother to her Bengal cat.
“I’d describe myself as full of life and full of energy; you guys can expect a whole lot of entertainment,” she said.
Though she’s new to reality TV, many viewers might not realise that Holly has a very famous ex.
She previously dated Luxe Listings Sydney star Gavin Rubinstein, going public in August 2024 before quietly splitting just a few months later.
Edward, 31
Edward is an energetic housemate who has a haircut every Friday, loves a sit-down shower, and lives with his parents.
He has always been single and said he’ll struggle in the house with anyone who is “selfish”.
“I wear my heart on my sleeve, I’m a very honest person, I’ll make it fun, but I also don’t know how to turn on the dishwasher,” he added.
Mia, 23
Mia describes herself as “wild” and a “spicy Sri Lankan” who wants to bring her “loud mouth” to the house.
She’s single and has never been in love, and is looking to chat Big Brother’s ear off in the Diary Room.
“My biggest strength is holding people accountable, so that’s what I’ll be doing,” she promised.
Michael, 49
Michael owns a publishing company and has some strong opinions that will no doubt stir the pot.
“I’ve got a very low tolerance for woke people, people who are loud and obnoxious, and cyclists on the footpath,” he said.
He described himself as a “realist” with no filter and said he plans to bring his “no nonsense” attitude to the house.
How many people applied to be a housemate on Big Brother Australia 2025?
More than 20,000 Australians applied to be on Big Brother Australia in 2025, with applications for the season closing on September 1st.
Producers then had the gruelling task of reviewing each and every submission before casting the lucky housemates, who went into lockdown a week ahead of the premiere.
Is Big Brother Australia returning in 2026?
Channel 10 has yet to confirm if Big Brother Australia will return for a 17th season in 2026.
While the network held its annual Upfronts event on November 6th on the Gold Coast at the Big Brother house itself, it made no official comment regarding the future of the show.
It is understood that network executives will make a renewal decision in the not-so-distant future.
