The judges are joined by special guest Jamie Oliver, as the contestants prepare for a season of secrets and surprises.

In the first elimination challenge of the season, the contestants must cook a dish from their favourite childhood memory. The least impressive dish will send its cook home.

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

Contestants raid Shannon Bennett's fridge as they seek to create a tasty dish in 45 minutes, with the winner facing Vue de monde's Hugh Allen in the hope of winning immunity.

Jamie Oliver returns for another day in the kitchen, as contestants battle to secure a place in the first immunity challenge.

It's Grand Finale Day and whichever cook scores the most points across two rounds will lift the trophy aloft, claiming $250,000 in prize money and win the title of MasterChef Australia 2023.
