Sydney and Adelaide auditions.

Brisbane and Perth Deliver.

The Auditions continue in Melbourne

The 12 weakest performers in the onion dicing challenge are tasked with cooking a dish that will 'wow' the judges using only the limited ingredients available in the pantry.

Contestants are brought to Sydney's famous fish markets where their task is to prepare a two course seafood meal in just 2 hours. However that time must also be used to shop for ingredients and make their way back to the kitchen.

The top 20 contestants are revealed.

In an emotional invention test, the remaining five contestants are surprised to learn that there are no rules or restraints: they can cook whatever they choose with full access to the pantry.

Julie, Aaron and Linda are asked to make a tarte tatin (apple tart) using a basic recipe.

Martin Boetz takes on Brent in cooking the signature longrain dish of eggnet, pork, prawns, and cucumber relish,

In today's seafood banquet team challenge, Brent was given captainship of the blue team for winning the invention test and chose Geni as the captain of the red team.

The blue team, headed by Brent, face elimination.

Poached egg salad with tomato tea (consommé), roast saddle of rabbit with white bean puree, ricotta tortellini, eton mess. The chefs expressed surprise that Brent had been voted off. Calombaris said, "Interesting. Really interesting."

Todays mystery box challenge includes chocolate, oranges, eggs, sugar, coconut, flour.

Michelle, Sam and Kate had to follow a basic recipe to cook chargrilled, stuffed squid in their challenge. Despite not having the time to cook her squid, Kate managed to produce the best of the three. Michelle's was deemed worse than Sam's and she was sent packing.

Julia and chef Peter Evans compete in preparing tea-smoked duck breast with ravioli with water chestnut, pear, and duck liver with blood orange sauce, spinach, and crispy fried ginger.

Today's challenge is a three-course meal in one hour using a limited pantry to be served to Matt Preston and fellow food critics Simon Thomsen and Larissa Dubecki.

At elimination, most of the team feel that Josh's abilities were inadequate and believe that he was the main flaw in determining their loss. Almost all the team, with the exception of Julie voting for Geni and Josh himself voting for Aaron, vote for Josh, sending him home.

Chilli and Fennel Squid, Chinese Mushroom Stir-fry with Tofu, Chocolate and Jaffa Soufflé. The chefs express surprise that Josh had been the one voted off.

Today's mystery box challenge include eggs, chili peppers, ale, potato and a whole red snapper.

Trevor, Sam and Tom make a Sticky Date and Toffee Pudding with Butterscotch Sauce and Almond Praline from a provided recipe. There are only minor flaws in each, but overall Tom's is deemed the best. The judges choose to spare Sam and Trevor as the differences between the dishes are too trivial.

Chris competes with Alex Herbert of Bird Cow Fish making one of her signature dishes, Potato Gnocchi with Sauteed Prawns in a Burnt Butter Sauce. He has an hour and forty-five minutes, she has an hour and fifteen. The judges give Chris 7/8/6 and Alex 8/9/8 out of ten. Winner: Alex Herbert.

Today's challenge sees both teams with a $750 budget. Red team made lamb skewers with yogurt sauce, aroncini balls, toffee apples, caramelized pineapple skewers. Blue team made lamb kofta with yogurt relish and mushroom risotto.

At elimination, Sandra and Kate both receive an equal number of three votes, Sandra for her service and Kate for her lack of cooking skills and leadership qualities. Kate being the team leader decides to vote herself out to pursue a pastry apprenticeship outside MasterChef.

Snapper in a Bag and Chunky Chips, Risotto with Pumpkin and Goat's Cheese, Rib Eye Steak with Red Wine Sauce and Spinach.

Today's mystery box challenge requires contestants to make cupcakes. John Torode of MasterChef UK serves as guest judge.

Aaron, Sandra and Julie faced elimination and had to make paella. Sandra produced the best whilst Aaron's overconfidence saw him neglecting to taste, and hence, did not achieve a correct balance of spices. Ultimately, he was sent home.

Justine competes with Guy Grossi of Grossi Florentino making one of his signature dishes, Lobster with Russian salad. She has an hour and thirty minutes, he has an hour. The judges give Justine 7/7/6 and Grossi 7/7/7 out of ten. Winner: Guy Grossi beat Justine.

Contestants must prepare a three-course meal to be served at the Sydney's Flying Fish restaurant.

Sam was scolded by the judges for producing the worst of the dishes of the Blue Team and Trevor was criticised for his choice to use bait as ingredients for the meal. In the end, Trevor voted for Sam, but Trevor's choice to use the bait, which made the food "taste like the bottom of a boat," was enough to see him have majority of votes to send him home.

Lobster Linguine, Tuscan Vegetable Soup, Roast Chicken with Buttery Potatoes, Lemon Diva cupcakes.

Contestants are thrown a curve ball. Instead of a mystery box, they face a taste test, with the contestant who correctly guesses the most ingredients of the dish will win an advantage in the invention test.

Tom, Poh, Chris and Julie had to make Croquembouche. Despite an unsettling start, Poh went on to produce the best dish. Julie came in second leaving Tom and Chris as the two worst. In the end, Tom was eliminated.
