MasterChef Australia

Andy Allen welcomes three new judges- Sofia Levin, Poh Ling Yeow, and Jean-Christophe Novelli. The contestants cook a dish that represents their 'new beginning' to impress guest judge Jamie Oliver.

The 22 contestants are thrown into their first big Service Challenge. With Jamie Oliver running the kitchen, they must feed 40 returning MasterChef Legends with a three-course meal.

The top five cooks have the chance to compete in an immunity challenge and avoid the first elimination of the season. But first, they need to complete Sofia's `wrap your hands around this' challenge.

In the first immunity challenge of the season, five contestants have to choose between one ingredient and 90 minutes to cook, or up to 20 ingredients with only 45 minutes to cook them.

With 75 minutes on the clock, the judges task contestants with preparing a dish that best represents their food dream for the first elimination challenge of the season.

The chefs make a dish from Mystery Box ingredients chosen by Jamie Oliver's parents, Trevor and Sally, and the four weakest dishes will send their makers into the next day's elimination.
