Expect the unexpected with a season of secrets and surprises. Judges Melissa Leong, Jock Zonfrillo and Andy Allen are joined by special guest Jamie Oliver.

Jamie Oliver is back for another day in the MasterChef Australia kitchen!

Contestants must bring their A-game if they want to secure one of two spots in the first Immunity challenge of the season.

It's a new era for MasterChef Australia as Andy Allen welcomes three new judges: Sofia Levin, Poh Ling Yeow and Jean-Christophe Novelli, plus guest judge Jamie Oliver. The contestants were tasked to create a dish that represents them. The winner will win the only immunity pin of the season and a trip to London to work at Jamie Oliver's latest restaurant for a week.

It's Day Two in the MasterChef Kitchen and already the 22 contestants are thrown into their first big Service Challenge, with Jamie Oliver running the kitchen.
