MasterChef AU Season 12

Team Challenge. Each team must cook two dishes: one main and one dessert. Each contestant has 20 minutes to cook and they have just 45 seconds to hand over the dish to the next contestant in the relay.

Josh Niland of The Fish Butchery breaks down a kingfish for each of the contestants to choose a cut to cook with. The contestant with the least impressive dish will be going home.

Tonight's immunity challenge is fought in two rounds. In one round contestants must create a delicious dish using instant noodles. The top two from round one must make a nostalgic and comforting dish.

Contestants must create a vegan dish using at least one ingredient from the mystery box set by vegan chef, Shannon Martinez. The top four dishes will cook off in tomorrow's immunity challenge.

Pressure Test. Contestants must replicate chef Peter Gunn's 'Black Box' from his restaurant Ides. The contestant with the least impressive dish will be going home.

Jo Barrett and Matt Stone from Oakridge Wines mentor this service challenge, with each team cooking a sweet or savoury menu. The team with the least impressive menu faces the pressure test.

Contestants are cooking off against the other contestant on their bench. The best dish from each bench will be safe, while the remaining contestants must cook in the elimination round.

Immunity Challenge. Katy Perry guest judges a very special Hot 'N' Cold challenge to honour the iconic MasterChef theme song. The contestant with the best dish will find themselves safe from the elimination.

Contestants have 75 minutes to cook a dish using one or more of the eight ingredients in the mystery box. The contestants are pushed to the limit when a twist is delivered to their benches.

Contestants have three hours to complete a simply stunning Darren Purchese dish, but in the final hour of the cook, a twist that no one could anticipate is thrown at the contestants.
