Contests are put in teams to complete a Mystery Box challenge with eight of the ugliest ingredients. They have an hour to make something delicious and beautiful.

The top 24 contestants enter the kitchen for their first mystery box challenge to create a dish with ingredients chosen by 2015 MasterChef Australia winner, Billie McKay.

The bottom three contestants face-off in the elimination pressure test. They must recreate two of guest chef Ross Lusted's signature dishes in two hours.

Contestants create grape based dishes in the Nappa Valley to win a fast-track ticket to finals week.

The contestants are split into two teams for a service challenge. Each team must cook a three-course meal for 30 people, replicating dishes from two celebrated Melbourne restaurants.

The contestants are sent on an off-site team challenge to mark the celebration of Chinese New Year and are joined by guest mentor, Kylie Kwong. Each team must prepare two set-price Asian street food dishes and sell them to the public.
