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 contestants arrive on the beautiful sunny shores of Noosa beach, met by the judges in front of one of Australia's most iconic surf clubs, the Noosa Heads Surf Lifesaving Club.

Rick Stein joins the judges and chooses the ingredients for the next mystery box challenge, including cuttlefish, pine nuts, basil, garlic, tomatoes, Australian raisins and marrow bones.

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.

Legends week continues as Yotam Ottolenghi hosts a deli item challenge; the first three contestants to incorrectly name a deli item must cook to stay in the competition.
