Big Brother Australia's format
Big Brother Australia is a reality TV show based on the international Big Brother format. The show features a group of contestants, known as "housemates", who live together in a specially constructed house that is isolated from the outside world. The housemates are continuously monitored during their stay in the house by live television cameras and personal audio microphones.
Throughout the competition, housemates are evicted from the house and eliminated from the competition. The evictions are determined by viewer voting, with housemates not being allowed to discuss nominations. Most seasons do not feature any regular competitions for power or safety. However, in seasons 5-8, there were Friday Night Games and Showdowns in season 10.
Every week, the housemates participate in nominations, a secret voting process to determine who will be nominated for eviction. Each housemate nominates two other housemates in the Diary Room, providing full reasons for their nominations. The three or more housemates with the most nominations are then nominated and face Australia's vote.
In 2020, the Seven Network revamped the format of the series to resemble the American and Canadian editions, with housemates deciding on nominations and evictions among themselves. This new format emphasised the competitive aspect of surviving the eviction process and allowed housemates to strategise and collude. However, the Australian public still decided the eventual winner, rather than a "Jury" of evicted housemates as in the American and Canadian versions.
The series aims to feature "real people" in the house through personality testing and engaging with people from diverse backgrounds across the country.

Housemates' nominations
Big Brother Australia is a reality TV show where contestants, referred to as "housemates", live together in a specially constructed house that is isolated from the outside world. The housemates are continuously monitored during their stay in the house by live television cameras and personal audio microphones. Over the course of the competition, housemates face nominations and evictions to eliminate other housemates from the game. The last remaining housemate wins the competition and is awarded a cash prize.
During the nomination process, each housemate nominates two other fellow housemates in the Diary Room, providing full reasons for their nominations. The three or more housemates with the most nominations are then nominated for eviction and face Australia's vote. In addition, each week, the housemates vote for one housemate to become the Head of House. The Head of House is immune from eviction for that week and has access to the Head of House Suite, along with two housemates of their choice. They also have the power to control the game and the nominations.
In the 2022 season of Big Brother Australia, housemates included Aleisha, Johnson, Lara, Lulu, Mel, Reggie Sorensen, Taras Hrubyj-Piper, and more. On 28 June 2022, housemates celebrated their first-ever Panic Room win after a successful effort from Estelle and Brenton. On the same night, housemates Aleisha, Reggie, Taras, and Tim experienced a twist of fate that changed their fortune.

Evictions
The eviction process in Big Brother Australia has varied across seasons. In some seasons, housemates nominate two other housemates for eviction in the Diary Room, providing reasons for their nominations. The housemates with the most nominations are then nominated for eviction and face Australia's vote. In other seasons, the power of nomination has been given to the viewers, with the housemates receiving the fewest votes being evicted.
In 2020, the Seven Network revamped the format to resemble the American and Canadian editions, with housemates deciding on nominations and evictions among themselves. This new format emphasised the competitive aspect of surviving the eviction process, allowing housemates to strategise and politic. Despite this change, the Australian public still decides the eventual winner, rather than a "Jury" of evicted housemates as in the American and Canadian formats.
In some seasons, each week, the Head of Household (HOH) is crowned and they must nominate two housemates for eviction. The Power of Veto (POV) competition gives nominees a chance to save themselves, and the winner decides whether to replace a nominee or use the veto on themselves.
The threat of eviction every episode keeps both the housemates and viewers engaged. The voting process usually lasts a week, with nominations taking place at the beginning of the week and evictions at the end.

Past seasons
Big Brother Australia has had a total of 15 seasons so far, with the sixteenth season set to air in 2025. The first season of the Australian reality television series Big Brother aired in 2001 and was a huge ratings success, averaging 1.4 million viewers. The show is based on the international Big Brother format, where a group of contestants, known as "housemates", live together in a specially constructed house that is isolated from the outside world. The housemates are continuously monitored by live television cameras and personal audio microphones. Throughout the competition, housemates are evicted, and the last remaining housemate wins a cash prize.
The first eight seasons of Big Brother Australia aired on Network Ten until the network cancelled it in 2008 due to audience erosion and controversy. The show returned in 2012 on the Nine Network for three seasons. In 2019, the Seven Network picked up the series, which ran for four regular seasons and a celebrity edition titled Big Brother VIP. The fifteenth season, which aired in 2024, received poor reviews, and a planned sixteenth season was cancelled. However, it was later confirmed that the show would be returning to Network 10 for its sixteenth season in 2025.
The cash prize for winning Big Brother Australia has varied throughout the seasons. For the first three seasons and seasons 8-10, the prize was guaranteed to be $250,000. Seasons 11 and 12 intended to have the same prize amount but tasks and challenges resulted in the prize decreasing to $200,000 and $234,656, respectively. Season 4 offered a guaranteed prize of $1,000,000, while Seasons 5 and 6 introduced a fine system, resulting in lower final prizes. Interestingly, Season 7 was advertised as having no prize money.
The format of the show has remained largely unchanged from other international versions of Big Brother. Each week, housemates nominate two people to be up for eviction, and the viewers then vote to decide who will be evicted. The finale typically involves the viewers voting for the winner from the final three housemates. Some variations have been introduced in certain seasons, such as intruders entering the house and facing eviction votes, immunity challenges, and fake evictions.

Celebrity editions
Big Brother Australia has had several celebrity editions over the years. The first celebrity edition aired in 2002, with Dylan Lewis being crowned the winner over runner-up Jay Laga'aia. The series lasted for 23 days, from July 21 to August 12, 2002, and a portion of the profits from eviction votes went to charities. The same house from Big Brother 2 was used, with slight remodelling, and the bathroom was off-limits to cameras.
In 2015, there were rumours of a Celebrity Big Brother revival on the Nine Network, but this was replaced by Celebrity Apprentice Australia. The Seven Network later picked up the series and aired a second celebrity instalment, titled Big Brother VIP, which featured several guest celebrities appearing briefly, including Carla Bonner and Bert Newton.
In 2021, a third celebrity season was announced, but due to poor ratings, it was later cancelled. Big Brother will be returning to Network 10 in 2025 for its sixteenth season, with comedian and radio personality Mel Tracina as the new host. While it is not confirmed if this season will include celebrities, the promo advertised the series' return to its original format with 24-hour live streaming and live nominations and evictions.
