This evening all the housemates will nominate face-to-face and around a campfire, revealing their choices with playing cards.
Luke S, Sara and Scott's victory comes after a series of Western-themed challenges, which have included dance-offs and spaghetti-eating contests.
The accumulated amount of gold from all the teams in the Rocky River of Gold task will decide whether or not the housemates passed or failed this week's shopping task.
