Big Brother Australia 2006, also known as Big Brother 6, was the sixth season of Big Brother Australia, and was aired on Network Ten in Australia. The series began on 22 April 2006 and finished on 31 July 2006; a duration of 101 days. In the auditions, which had been held in November and December 2005, producers asked for contestants who were "smart, strong, and looking for a fight". The Launch was aired on the evening of 23 April 2006 (a 24-hour delay). Fifteen housemates initially entered the house on Day 0, with the addition of three Intruder housemates entering the Big Brother House in Week 4, another three Intruders in Week 9, and two replacement housemates entering in Week 12. On Day 100, Jamie was declared the winner of Big Brother 2006, with Camilla the runner-up. At the time it was the closest winning margin in any Australian series of the show, later beaten by Series 7 in 2007.
