The format used for "Big Brother" in Australia remained largely unchanged from that featured in other editions of the series, though some differences were incorporated. "Big Brother" is a game show in which a group of contestants, called Housemates, live in isolation from the outside world in a custom built "house", which includes everyday facilities such as a fully equipped kitchen, garden, two bedrooms, and a bathroom. The house is also a television studio with cameras and microphones in most of the rooms to record the activities of the Housemates. The only place where Housemates can escape the company of the other contestants is the Diary Room, where they are encouraged to voice their true feelings. Not all Diary Room footage is broadcast due to the privacy of the contestants. Each week all Housemates nominate two of their fellow contestants for potential eviction. They award two points to one Housemate, and one point to another. Failure to do so may result in a punishment, such as a reduction in the prize fund. The three, or more, Housemates with the highest number of nominations face a public vote conducted by phone, with the contestant receiving the most votes being evicted from the house. The last contestant remaining in the house is declared the winner and is awarded a cash prize of $250,000. On eviction night, host Gretel Killeen would inform the nominees which of them had been evicted from the house. Following the announcement, the evicted Housemate had to gather their belongings and exit the house. Upon exiting through the house's front door, Killeen led the evictee into a studio where they met with their family and friends. While in the studio, Killeen had an interview with the evicted Housemate, and showed their best bits - a video compilation of their time in the house.
