In 2003, Sorensen won
third season of
Big Brother with 72% of the final vote, the biggest margin in a
Big Brother finale to date, in addition to being the first female winner of the Australian show. Sorensen was involved in the week 12 task on season 9 of
Big Brother 9 in 2012, the show's comeback season on the
Nine Network. She was one of several former housemates that entered the house to try to get the current housemates to fail their weekly task, which was to ignore everyone who entered the house that was not a housemate. In 2022, Sorensen starred in a third network, the
Seven Network's, iteration of Big Brother,
Big Brother 14, as one of eight past housemates, in the mix with newly cast stars. She was one of three former winners to enter the house, alongside
Big Brother 4 winner
Trevor Butler and
Big Brother 10 winner Tim Dormer. She was ultimately crowned the winner of
Big Brother for a second time, where she spent a total of 148 days in the house (in both seasons). She became the fifth contestant in the world to win the show twice and the first person to do so in
Big Brother Australia, also she was the first female winner of
Big Brother since Terri Munro won the eighth and final season on Network Ten in 2008. ==Personal life==
