The amateur cooks have one hour to recreate their signature dishes for the judges' first auditions, as the judges and nine past winners offer their support.

Three chefs fight for survival in the first elimination challenge. They are given 75 minutes to cook a dish with ingredients from their home fridge and pantry.

The top 24 try to stand the heat in the kitchen, with 90 minutes and an open pantry to cook their dishes and impress the judges, focusing on hospitality.

The winners from the Sweet Week mystery box go up against the winners of Zumbo's invention test for immunity that will last for the next two rounds of the competition.

The contestants visit Maggie Beer's Eatery in the Barossa Valley for their elimination challenge, and participate in a masterclass at the Adelaide Markets.

After giving out 18 aprons, the judges are searching for six more cooks to complete their top 24, and the chefs who were offered a second chance go head-to-head.
