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.

The top 24 contestants face a mystery box containing ingredients selected by season seven champion Billie McKay.

Contestants face an off-site challenge at George Calombaris' Hellenic Republic restaurant. Divided into two teams, they must prepare a three-course feast for 120 guests to avoid elimination.

The team challenge is all about the pub lunch. The contestants are split into two teams and must cook three courses for 70 people with Marco Pierre White running the pass.

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.
