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.
The cooks face a mystery box challenge, choosing from ingredients including lemons, tarragon, calamari, spatchcock and mangoes.
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.
The contestants are outside the studio for the first time, preparing a feast for the 150 volunteer truckers of Lions Need for Need, who deliver fodder to farmers in need across Australia.
Nigella Lawson week continues and the four best cooks from her Mystery Box challenge must cook a dish that celebrates custard; the top contestant will compete against Coskun Uysal, of the renowned Tulum restaurant.
