Contest Event: 1 Tonne of Bricks (7x19)

Uitzenddatum: Feb 21, 2012

Hayley explained that Immunity Week was about to commence, giving contestants multiple chances to keep themselves safe. Graham returned from the Elimination Room, much to the relief of his team. Luke gave his all in training, feeling guilty for Ryan's exit, while Hamish gave his best performance yet. Lydia broke down in Red Team training, although Michelle helped her resolve to lose a bigger number at the next weigh-in. Tired of his team's "hot air", The Commando made absolutely sure Graham was getting his "no excuses" message. For the first of the Immunity Challenges, the contestants had to move bricks by hand from one pallet to another. The first to transfer all of theirs won both safe passage and a 24-hour pass home. In a tight race between Margie and Luke, it was the Blue Team member that took the win. Hayley then surprised the other competitors with a fresh game twist.
