Trevor Butler was a contestant and winner of Big Brother Australia Series 4 (airing in 2004). As well as being the first, and currently the only, contestant to win $1,000,000, as opposed to the $250,000 of previous seasons, he also boosted interest in the final eviction by proposing to his then-girlfriend Breea Forrest live on the eviction stage.There was some controversy regarding how much of his winnings were taken away as tax. At one point the Australian Taxation Office (ATO) considered it to be payment for spending the time in the house, and therefore wanted to take nearly half of the winnings away. The ATO eventually gave in and did not take the money.
