Contestants compete in the Quarter Final challenge using ingredients chosen by loved ones, cooking off for a place in the Semi Final.

Contestants must team up and create a three-course menu for 100 people in a pop-up restaurant challenge; 2016's runner-up Matt Sinclair guest stars to mentor the contestants.

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.
