It's Marco Pierre White Week on MasterChef Australia. The contestants have 75 minutes to create a dish from Marco's mystery box of ingredients with rewards and hazards for the top and bottom three.

The bottom three from the invention test must keep up with Marco as he demonstrates his classic John Dory dish. With no recipe or clock, who has cooked their last dish?

The contestants from the losing pub lunch challenge team must correctly name an ingredient to avoid the elimination cook-off challenge, as the contestant with the least impressive dish will go home.

The top three contestants from the invention test must make a filled pasta with a matching sauce. The winner will then enter a cook-off for immunity against guest chef, Jake Kellie.

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.

Day four of Heston Week. Contestants must use ancient recipes and give them a modern twist.
