Watch The Biggest Loser (AU) season 1 episode 45 online for free. The final three (now known as the black three) refuse to answer the door to the remaining three intruders. After waiting outside for fifteen minutes, the black three answer the door to find that Cat, Harry and Jo returned. Only the three intruders were weighed-in at the weigh-in today. Who ever loses the most weight out of them will remain in the competition and be one of the final four. Jo jumped onto the scale with an ordinary loss of 2kg. Next was Cat who lost a disappointing 1kg. Harry had to lose at least 4kg to win. He lost an amazing 10kg and was rewarded by being back in the final four. Harry was given his black shirt, but as he put it on, Kristie, Adro and Fiona took theirs off. When Harry climbed on the stool, Kristie, Adro and Fiona took a step back.
