Secrets & Surprises - MasterChef Australia

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.

There's a catch to the flavour bombs that Jamie Oliver has left behind for the contestants to cook with today - they will only be revealed 15 minutes into the cook and must be included in the dish.

Contestants must raid Shannon Bennett's fridge to create the tastiest dish in 45 minutes. The winner will go head-to-head with Vue de monde's Hugh Allen in the hope of winning an elusive immunity pin.

Contestants fight to stay alive in the first elimination challenge of the season. Cooking from favourite childhood memories, the least impressive dishes over two rounds will send its maker home.

This season's first Mystery Box sees fan favourite Poh Ling Yeow back in the MasterChef kitchen for one night only. Contestants must create a winning dish with just under bench staples and little else.

Former MasterChef winner and dessert queen Emelia Jackson is here to share her secrets. Using Emelia's choux pastry recipe, contestants must create a superb sweet or savoury dish to avoid elimination.

Get your orders ready, its time for the first Service Challenge of the season. Two teams, aided by mentors Matt Sinclair and Sashi Cheliah, must cook an entree and a main course dish for 30 diners.
