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

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.

After being split into teams, the contestants cook a three-course meal for 30 guests from two Melbourne restaurants.

The top contestants open four Heston Blumenthal-inspired and supervised pop-up restaurants in four days; begin with galaxy-inspired dishes in a revolving restaurant.

A féte in Negella Lawson's name is held and the contestants are split off into three teams. The teams must prepare one savoury dish and two sweet dishes to sell, with all proceeds donated to the Royal Children's Hospital.

Three contestants create midnight snacks for the chance to cook against Lachlan Colwill for an immunity pin.
