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.
The Biggest Loser Australia: Couples 2
The fifth season of the Australian version of the original NBC American reality television series "The Biggest Loser", known as The Biggest Loser Australia: Couples 2, premiered on 31 January 2010 on Network Ten. This season saw Australia's first female Biggest Loser. 41-year-old education assistant Lisa was the winner, dropping 56.2 kg from her 121.9 kg starting weight - or 46.10% - to become the first woman to win the competition. Also, she is the first contestant to double her prize money since she was crowned The Biggest Loser with the Double bracelet on her wrist.
The two bracelets were introduced in week 1, and have moved around over the course of the series due to Eliminations, non-elimination penalties, biggest loser rewards and challenges. The Double bracelet has the power to double the prize money (to a maximum of $400,000) if worn by the winner of the overall competition, while the Nothing bracelet has the power to deny the prize money (so they win no prize money) if worn by the overall winner. If the wearer of a bracelet is eliminated, that person must choose onto which of the remaining contestants to pass their bracelet. Lisa won TBLC 2010, and was wearing the Double bracelet, but by the finale the prize money had been reduced to $185,000, so she won double that amount ($370,000).
