The secret power given to the last task's winning project manager is revealed, but how does the last person to be fired get involved in the decision? The seven remaining celebrities have to set up a pop-up display cube in a shopping centre for Australian furniture brand Koala, and score points for leads by getting customers to fill in Koala's leaf forms. Koala's vice president gets among the shoppers as an undercover boss, and can award teams with up to 30 bonus points based on her experiences. The team with the higher point score will win A$20,000 donated by Koala to their project manager's charity, while the losing team return to the boardroom, where after they discuss what went wrong, one of them is fired.
