Network Ten's cancellation in 2008
Big Brother Australia, also known simply as Big Brother, is an Australian reality TV show based on the international Big Brother format. The show features 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 eliminated through eviction, with the last remaining housemate winning a cash prize.
Big Brother Australia first aired in 2001 and initially ran for eight seasons and one celebrity edition on Network Ten. In July 2008, the show was cancelled by Network Ten following audience erosion and controversy. The eighth season of the show, which aired in 2008, was also the last to be hosted by Gretel Killeen, who had been the main presenter of the series since its inception. Killeen's absence left viewers disappointed and contributed to the season's declining ratings.
The show faced criticism and controversy during its run on Network Ten. It was occasionally referred to as "Big Brothel" in the press due to the sexual content of the "Uncut" episode. This episode led to complaints and an investigation by the Australian Communications & Media Authority, which found that Network Ten had breached the industry code of practice by broadcasting footage that exceeded the maximum MA15+ rating for Australian commercial television.
On July 14, 2008, Network Ten confirmed that the 2008 season would be the last to air on the channel, citing a decrease in ratings for the daily shows as the reason for their decision. The cancellation sparked rumours about a possible revival by other networks, but it was not until 2012 that the show returned for its ninth season on the Nine Network.
After its cancellation by Network Ten in 2008, Big Brother Australia continued to air on different networks with varying levels of success. The show underwent several revivals and changes in format, hosts, and networks. In 2024, it was announced that Big Brother Australia would return to Network Ten, now known as Channel 10, for its sixteenth season in 2025, marking a return to the original network after a 17-year hiatus.

Celebrity Big Brother US in 2018
In 2018, "Big Brother" made a return to Australian television with the Nine Network airing the first season of Celebrity Big Brother US. The show's logo was specially designed to resemble the eye logo of Nine's previous iteration of Big Brother Australia. Episodes were made available on the 9Now streaming service soon after airing in the US, with televised broadcasts beginning on February 11, 2018, on 9Go!
The US edition of Celebrity Big Brother in 2018 was the first of its kind, hosted by Julie Chen and featuring 11 houseguests from diverse backgrounds, including actors, actresses, singers, and athletes. The season was shorter than the usual 90+ days, and the house design was inspired by the Los Angeles skyline, featuring glitz and gold.
The Australian broadcast of the US Celebrity Big Brother faced challenges due to low ratings, resulting in a timeslot change just three days after its premiere. The show was moved from 9:30 pm to 11:30 pm. Despite these adjustments, no further American seasons of Big Brother were aired in Australia.
In terms of the format, the celebrity edition of Big Brother differed from the regular seasons. While regular seasons typically feature houseguests vying for prize money, the celebrity edition may involve donating the winnings to a charitable cause. Additionally, the dynamic of having celebrities as contestants brought a unique element to the show. Some viewers criticised the 2018 season for being overly political and scripted, taking away from the fun and excitement expected from the show.
Big Brother Australia has a long history, first airing in 2001 and running for eight seasons and a celebrity edition on Network Ten. The show was then cancelled in 2008 due to audience erosion and controversy. However, it was revived in 2012 on the Nine Network and has since continued with various seasons, hosts, and format changes.

The Seven Network's revival in 2020
Big Brother Australia first aired in 2001 and ran for eight civilian seasons and one celebrity edition on Network Ten. In July 2008, the show was cancelled following a decline in ratings and controversy. However, the show was revived in 2012 and aired on the Nine Network for three seasons. In 2019, the Seven Network acquired the rights and confirmed that the show's second revival would launch in June 2020.
The Seven Network's revival of Big Brother Australia in 2020 brought significant changes to the show's format and presentation. The season, also known as Big Brother: Revolution, marked the show's second revival and first season on the Seven Network. It introduced a new logo for the franchise, adopting a variant of the redesigned international logo of the Big Brother franchise with a flat, digital eye design. This change was reflected in the season's tagline, "The Game has Changed," indicating a shift in the show's gameplay.
The 2020 season of Big Brother Australia was pre-recorded, marking the first time the show was not aired live. The decision to pre-record the season was made due to the COVID-19 pandemic, with filming ending in April 2020 to ensure the safety of those involved. The season featured a wide age range of housemates, from 19 to 62 years old, the most diverse age range since Big Brother Australia 8.
In terms of format, the Seven Network's revival reshaped the show to resemble the American and Canadian editions. The new format emphasised the competitive aspect of surviving the eviction process, allowing housemates to strategise, politic, and collude about nominations and evictions. While the American and Canadian versions have the evicted housemates decide the eventual winner, the Australian version retained the public's role in choosing the winner.
The 2020 season of Big Brother Australia also introduced a new house location. The show moved from its previous compound on the Gold Coast to a converted warehouse inside the North Head Sanctuary in Sydney. The new house featured a modern eco-style interior design, with living walls, wood panelling, and LED lighting and screens. An adjacent activity area, similar to Network 10's Friday Night Live arena, was constructed for weekly challenges.
