The cast ranges in age from 22 to 62, with family connections adding another layer to the game. Reggie Bird’s sister Anita and former housemate Kieran Davidson’s mum Pam both have links to earlier seasons, while Ryan and Tahlia are siblings keeping their own connection under wraps.

Following the 26 October premiere, host Mel Tracina’s new group is settling into the Brisbane house and competing for $100,000.

Anita

Age: 47
From: Tasmania
Occupation: Travel advisor

Anita has a family connection that long-time Big Brother fans will recognise immediately: she is two-time winner Reggie Bird’s sister.

The Tasmanian travel advisor has spent years caring for her parents full-time and is now taking the opportunity to do something for herself. Her interests include skateboarding and solo travel, and she has even taken a mannequin on a road trip across the country.

10 describes her as warm, nurturing and spontaneous, with a strong commitment to kindness and being herself. She also shares the unfiltered streak that made her sister such a familiar face.

Austin

Age: 22
From: Queensland
Occupation: Carpenter

Austin works alongside his dad and brother in the family carpentry business. At 22, he is the youngest housemate in the announced cast.

Away from the tools, he spends his weekends surfing with mates and heading to the pub. He is bringing a relaxed, sociable approach to the house, along with the practical skills to tackle a broken chair if one needs fixing.

His aim is to win people over, with 10 pitching him as a young tradie who enjoys keeping everyone laughing.

Charity

Age: 29
From: New South Wales
Occupation: Door-to-door field manager

Charity was born in Kenya to a Sudanese family and came to Australia as a seven-year-old refugee, arriving without any English. She grew up as one of 13 siblings, so sharing space with a large household is familiar territory.

Family and faith are central to her life, while her work as a door-to-door field manager gives her plenty of experience meeting people.

Charity believes television is where she belongs. Her official profile promises an outgoing personality and someone who is comfortable saying what she thinks.

Ebony

Age: 23
From: Victoria
Occupation: Entrepreneur

Ebony is a self-made entrepreneur who has always worked for herself, and she has no intention of leaving her confidence at the door.

She is focused on the prize money rather than a house romance. Her official profile says she has never been kissed and is determined to keep distractions from getting in the way of winning.

Slow walkers, loud chewing and feet are among her pet hates. Ebony knows her strong opinions may cause friction with other housemates, but she is comfortable making them heard.

Harmon

Age: 29
From: Queensland
Occupation: IT salesman

Harmon’s working life has taken in mining, crypto and podcasting before his current job in IT sales. His approach to the house comes with a warning for anyone hoping for a quiet stay: he enjoys provoking a reaction.

He grew up in a strict immigrant household where his mum was both his teacher and principal. These days, his official profile describes someone who likes testing people’s patience and seeing what happens when he pushes their buttons.

Keeping the peace is unlikely to be his first priority.

Heath

Age: 23
From: Queensland
Occupation: Engineering student

Gold Coast engineering student Heath has interests well beyond his degree. He fronts a band, surfs, makes jewellery and sews and alters his own clothes, while spending his spare money on travel.

His friends describe him as energetic, social and willing to try almost anything. He also prides himself on being able to read a room and turn a conversation into a connection.

Beneath that easygoing exterior, 10 says there is a strategic mind. His enthusiasm for meeting people comes with an eye on the game.

Kyrah

Age: 25
From: New South Wales
Occupation: Secondary school Drama and English teacher

Kyrah teaches Drama and English at the high school she once attended. She is one of seven children, a twin, and newly single after a five-year relationship.

Diagnosed with ADHD and autism at 15, Kyrah describes a life full of distractions, lost belongings and running late. Her official profile also highlights her academic ability, competitive streak and extensive store of trivia.

She has a loud laugh, little ability to hide what she is thinking and plenty of experience commanding a room. If the house faces a general knowledge challenge, that collection of random facts could prove useful.

Marshy

Age: 24
From: South Australia
Occupation: Forklift salesman

Andrew, known as Marshy, is a forklift salesman whom 10 describes as Toyota’s reigning forklift salesman in Australia. Now he is chasing another win in the Big Brother house.

A lifelong local AFL player, he loves sport and has built a budgie smuggler collection that has reached double figures. He is single, enjoys dating and calls himself the “Italian Jason Momoa”.

Marshy is backing his sales skills and sense of humour to help him connect with people. Keeping secrets may be more difficult: his official profile says that is something he struggles with.

Matthew

Age: 37
From: Victoria
Occupation: Property investor

Matthew is a property investor who considers his personality one of his biggest assets. Confident and comfortable speaking his mind, he is heading into the house without plans to tone himself down.

He enjoys a debate and says he respects differing views, but dislikes being told what to think. That combination could make for some lively conversations around the house.

There is also a performance streak behind the property career. Matthew can rap and breakdance, giving his housemates something else to discover beyond his opinions.

Matty

Age: 39
From: Western Australia
Occupation: Mining commentator and former FIFO miner

Matty calls himself a “textbook Aussie bogan”, but he enjoys surprising people who underestimate him. The former FIFO miner has both a Mining Engineering degree and an MBA.

Now working as a mining commentator, he is described by 10 as quick-witted, sociable and always ready for a laugh.

He is also a dad to two daughters, aged six and seven. His official profile puts loyalty to his children and his mates at the centre of who he is, beneath the bravado.

Pam

Age: 62
From: South Australia
Family connection: Mum of former housemate Kieran Davidson

Pam is the oldest member of the announced cast at 62, and she already has a close connection to the show. Her son is former housemate Kieran Davidson, who competed in Season 12.

She is competitive, outspoken and comfortable socialising with people of different ages. Her official profile describes a friendly manner backed by a strategic approach, with little hesitation about speaking up when something bothers her.

Despite her motherly streak, Pam is not volunteering to cook for everyone. Given the choice, she would rather clean the toilets than take charge of dinner.

Pheobe

Age: 26
From: Queensland
Occupation: Bunnings café worker

Pheobe has worked at Bunnings for 11 years and is currently based in its café. She also has a musical theatre background and a habit of breaking into song or dance wherever she happens to be.

Her friends consider her the funniest person they know, and she is happy to take on the role of house entertainer. She is an ABBA devotee who has already chosen Chiquitita for her funeral.

Pheobe is also direct about what frustrates her, including insincerity and people taking too long to get to the point. After bad luck in love, she is open to finding someone who will “match her freak”.

Ryan

Age: 27
From: New South Wales
Occupation: Garden centre manager

Ryan is a garden centre manager with a big personality, a distinctive rat’s tail and a love of making people laugh. Proudly gay and Australian Italian, he is just as comfortable serving customers in a wig as calling everyone ‘darl’.

He is a devoted Susan Boyle fan, while his official profile describes a caring person who has experienced significant loss and values loyalty and family.

Family is particularly relevant to his time in the house: fellow housemate Tahlia is his younger sister. The pair’s relationship is one of this season’s secrets.

Tahlia

Age: 25
From: Victoria
Occupation: Horticulture, gardening and support worker

Tahlia is entering the house alongside her older brother Ryan, although their fellow housemates have a secret sibling connection to uncover.

Her work spans horticulture, gardening and support work, giving her experience getting along with people from many different backgrounds. She has a dry sense of humour and a reputation for finding herself in unusual situations.

Tahlia will miss her partner Charlotte while she is away. In the house, she is relying on her ability to form friendships and keep a conversation going, with the added familiarity of having her brother nearby.
