The eventual winner, as decided by percentage of weight lost, was Adriano "Adro" Sarnelli, who won A$200,000.
Adro had the highest percentage of weight loss, making him Australia's Biggest Loser for 2006 and the winner of A$200,000.
Coming in fourth was the lightest and youngest contestant, Fiona, who lost 29.5 kg (29.18%) and won A$10,000.
At the end of the show, Adro could only manage to yell, "this is unreal", as the stage was invaded by loved ones and eliminated contestants.
Wal lost 66.3 kg (37.52%) of his original weight, making him the biggest loser of those eliminated.
