Jamie Brooksby (born 28 June 1983) is a personal trainer from Claremont, Perth, Western Australia and was the winner of Big Brother 2006. He entered the house on Day 0 with the other 14 original housemates. He formed a romantic relationship with fellow housemate Katie. Jamie was up for eviction for the first time in Week 8, but Katie was evicted. He was then up for eviction the following week and again survived. Jamie was banned from nominating other housemates in Week 10 as a punishment for repeated rule-breaking including what Big Brother considered as Jamie discussing nominations (in particular, who nominated whom). The rules of the show ban any discussion about nominations to prevent housemate alliances from forming.
Jamie largely avoided conflict with fellow housemates. He admitted to not washing his underpants for over three months. He was compared to Ben Stiller's character Derek Zoolander from the movie Zoolander, not only because of his constant need to check his hair, but also because of his voice and his frequent usage of the word 'like.' A Big Brother show once showed a clip in which the amount of 'like's Jamie used in a thirty second discussion were tallied: eight. Although picked by Centrebet to be the runner-up, Jamie won Big Brother 2006 with 53% of the merged vote. He received $426,000 as the winner of the series. He joked that he would spend the money on a solid gold house and a rocket car, as Chester Lampwick did in The Simpsons episode The Day the Violence Died. On the night he was announced as winner, Jamie was reunited with Katie, and the pair proclaimed their love for one another.
Katie had heard little from Jamie since the finale, until 22 August when Jamie spent 24 hours in the window of Myer Melbourne as part of a Bonds underwear promotion, and Katie spent some of the time with him. He returned to Perth on 30 August 2006, for five days.
Many people will remember his as "the guy with the headband", and large appendage.
