Your favourites are back for another crack at the coveted MasterChef title. Up for grabs tonight is this season's only immunity pin and joining them all week is chef extraordinaire, Gordon Ramsay.

The losing team are given a series of condiments to identify, with the first five to guess incorrectly going straight to the elimination cook; Nigella hosts a Masterclass.

As the week in Western Australia nears its end, three of the contestants face an elimination challenge, with all of them desperate to make it through to finals week.

A group of home cooks prepare their signature dishes in the first of two audition shows, hoping to get a place in the main competition.

The amateur cooks are introduced to Secrets Week, throughout which a secret will be revealed every day, whether it be a secret ingredient, recipe, technique or even a secret chef.

The contestants are tasked with cooking a dish they would eat for the rest of their lives if they found themselves on a deserted island; they have an open pantry and 75 minutes to create something delicious.
