Big Brother is an Australian reality television show, and is the Australian version of the Big Brother franchise. Contestants are referred to as "housemates," and 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 as well as personal audio microphones. Throughout the course of the competition, housemates are evicted from the house. The last remaining housemate wins the competition and is awarded a cash prize. The series began airing in 2001, and as of 2022, 14 seasons and 2 spin-off seasons have been broadcast.
