Each hopeful cook has 60 minutes to produce their dish. If the judges like the dish, they're through to the next stage. If not, sadly, they're heading home.

It's day two of auditions and 13 contestants return for a second chance to show the judges they deserve to be in the top 24. With 18 aprons given away yesterday, just six aprons are up for grabs.

The pantry is open, there's 75 minutes on the clock, and the contestants are asked to cook the dish they'd cook every day for the rest of their lives if they found themselves on a desert island.

Contestants cook outside of the kitchen for the first time. Their challenge is to create a feast for volunteers, truckies, farmers and their families impacted by drought in Briagolong.

Before each cook sits their favourite and least favourite ingredients. Round one: cook with either. But those that produce the bottom four dishes face round two with their remaining ingredient. Followed by a Masterclass with Billie, Poh and Matt

It's Nigella Week. MasterChef favourite Nigella Lawson sets the mystery box ingredients. Whoever cooks the best dish heads into immunity, but the rest must compete in a relay invention test.

It's pressure test time for the losing team from the previous challenge. The contestants have 90 minutes to cook Nigella's infamous roast chicken with two sides and gravy. Who will fail to impress and be sent home?

Nigella 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 renowned Tulum restaurant.

Nigella and contestants are given historical recipes at the State Library of Victoria to inspire a three-course meal. The team who create the least impressive menu will head into the next elimination.

It's Secrets Week, and, after a quick workshop with Din Tai Fung's Edward Yulianto, our cooks must create a tasty dumpling dish and later invent a dish that incorporates a secret. Shh.

Three contestants face a pressure test and will cook a paella based on an award-winning dish by Leno Lattarulo from Melbourne's Simply Spanish. Simple, right? Wrong. It is Secrets Week, after all.

These immunity rounds involve sauce, secrets and citrus. A contestant will face off against an established chef that will be kept secret from everyone, including the judges, until the very end.

Each team is allocated a 'secret weapon' and must create a four-course Italian meal for 40 diners. Whichever team serves the least impressive meal will go into the next pressure test.

Secrets Week closes with the previous episode's losing team facing a blindfolded taste test. The first five to guess incorrectly have a 60-minute open pantry cook, but one last secret will ruffle some feathers.

This episode's mystery box challenge has contestants creating dishes using Queensland's finest ingredients. The judges will taste the five most appealing dishes and the winner will head into an immunity challenge.
