Big Brother (Australian season 7)
Big Brother Australia 2007, also known as Big Brother 7, was the seventh season of the Australian reality television series "Big Brother". Episodes were broadcast on Network Ten in Australia, and the first episode aired on 22 April 2007. 
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. In the finale Aleisha Cowcher was announced winner of "Big Brother Australia 2007". She won by the closest winning margin ever in the Australian series. The news the following day reported a margin of 51% versus 49% – a difference of 65 votes. This was the last season hosted by Gretel Killeen.
Brian Belo
Belo entered the "Big Brother" house on 15 June 2007, alongside Billi Bhatti, Jonathan Durden and Liam McGough. He was noted for his apparent ignorance in regards to William Shakespeare, claiming that he had never heard of the playwright. As Belo entered the final week of the competition, it was speculated that he would come in second place behind Sam and Amanda Marchant; Ladbrokes placed the Marchant twins as favourites at 2/7 and Belo at 5/2. However, Belo was announced as the winner of the series on 31 August 2007 with 60% of the vote to win. Belo was the youngest winner of the programme, until 2018 when 19 year-old Cameron Cole became the show's youngest ever winner.
