The fifth season of the Australian reality television series, Big Brother, also known as Big Brother 2005, began on 8 May 2005, with housemates going into the House the day before, and finished on 15 August 2005, lasting 101 days. The season was aired on Network Ten in Australia, and TV-2 in New Zealand with a four-week delay. Promos for the show suggested that Big Brother would be different this year, and phrases such as "Assume Nothing, Expect Anything", "Let's Play" and "Think Again" were used throughout the series, especially during Opening Night. The winner was announced on the finale that was watched by 2.282 million Australian viewers.
