This year the winner of Friday Night Live was given a greater power in nominations.
Replacing the Three Point Twist of previous seasons, the Friday Night Live winner each week this season was required to choose one nominated housemate to be removed from the nomination line-up, and to nominate another to replace them.
Adjacent to the kitchen was a new room called the "Chill Out Room".
As an official rule, no more than three housemates were allowed in the room at a time.
It provided a quiet place to talk or relax, away from the rest of the housemates.
On 23 April 2007, the four remaining wild-card housemates not selected to enter the House via the public vote on Days 1 and 2 were isolated in the "White Room".
Michelle joined him in the Punishment Room due to the weekly task which involved housemates remaining partnered.Despite a drop in ratings compared to previous series, and a number of controversies, the then Big Brother executive producer Kris Noble considers the year's series a success.At the end of this season's finale broadcast 30 July 2007, it was announced by host Gretel Killeen that Big Brother would be returning for an eighth season in 2008.The challenge was that the housemate who stayed in the White Room the longest without pressing the red button would become a legitimate Big Brother housemate and enter the main house with the rest of the housemates.Monitors in the Big Brother House allowed the housemates to watch, without audio, the White Room housemates at all times.
