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.
Rachel Rice
Rice entered the "Big Brother" house on 5 June 2008. During her stay in the house, Rice survived two eviction votes, the first in Week 8, where nine others faced eviction as a punishment for breaking rules, and the second in Week 10, where she survived over Stuart Pilkington. Rachel was known for being one of the nicer housemates in the show, though she was often teased by her fellow housemates as she often chose not to give opinions on matters that she considered sensitive. She also was known for the close friendships she formed with her fellow housemates – most notably Kathreya Kasisopa and Michael Hughes. Rachel was announced as the winner of her series on 5 September 2008, narrowly beating her friend Michael in the final night by 51.3% of the public vote. The result came as a surprise to the bookies, who had Michael as the favourite to win for several weeks.
