Honeymoon or Not?

The winner of the reward challenge chooses one person to enjoy a trip to the Great Barrier Reef to snorkel and partake in a feast. The immunity contest unfolds in three segments: "Know Your Ropes"; "Rock the Boat"; and "Sinking Ship". In each part, the players try to make their opponents lose their balance and fall into the water. Later, the ninth person is voted out of the game.
