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.

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.

This time, after being split into teams, the contestants are tasked with operating Adelaide's first ever `MasterChef' night market.

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.

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.

In the latest pressure test, the bottom three contestants have to recreate Alla Wolf-Tasker's Autumn-inspired duck dish.
