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.
Five contestants take on a service challenge at a Perth restaurant, preparing five courses for 20 diners; the makers of the best two dishes will join the cook-off for a final place.
The top nine are each given a mystery box which has appeared once before in the competition, to demonstrate how they have improved since last cooking with those ingredients.
Special guest Jock Zonfrillo from Restaurant Orana tasks the contestants with using native ingredients to create dishes.
For the mystery box challenge, contestants must cook with some of Coles' most popular ingredients, along with Vegemite, tomato sauce, or Milo.
