Big Brother Australia 15, also known as Big Brother Australia 2023, was the fifteenth season of the Australian reality television series Big Brother. The season began airing on 6 November 2023 on Seven Network.[1] Sonia Kruger returned as the host of the show. The series was initially teased as Big Brother: House of Love and featured a younger cast consisting of single housemates.[2]
On 6 December 2023 Tay & Ari Wilcoxson won the series becoming the second joint-housemate winners in the history of the Australian version of Big Brother, after the Logan twins won season 5.
In October 2022 Seven Network announced that Big Brother would return for a fifteenth season. It was initially given the title Big Brother: House of Love and was teased to feature "a younger cast of sexy singles looking for love".[3] The format was criticised on social media by viewers who said [the show] really needed to go back to the old Big Brother [format]". The series was again pre-recorded, and filming began on 31 October 2022.[4] [5] Following the criticism, the "House of Love" title was dropped, and after the conclusion of filming Seven Network described the series as the "spiciest yet" and a "more stripped-back, traditional Big Brother, where the cast is younger".[6] [7] It was also confirmed that the spin-off show Big Brother Uncut would return after seventeen years, having last aired during the sixth season.[8] The season ran for 25 days, the shortest civilian season in Big Brother Australia history.[9]
The season ended in a pre-recorded finale, similar to Big Brother VIP, where three possible endings were filmed for each of the finalist ahead of time with the outcome of Australia's vote determining which was broadcast.[10]
The season aired in New Zealand, with episodes being made available via TVNZ+ the day after their broadcast in Australia. The Uncut episodes were not made available.[11]
The housemates were revealed in October 2023 and were described by Seven Network as the "sexiest housemates in Australia".[12]
