Fan favourites return for another chance at the title where they compete to grab the season's only immunity pin.

Katy Perry guest judges a special Hot N Cold challenge to honour the iconic MasterChef theme song. The contestant with the best dish will find themselves safe from Sunday's elimination.

It's Suburban Takeover Week and the losing team from yesterday's Thai challenge are in today's Pressure Test.

It's the start of Suburban Takeover Week. The contestants take over a Thai restaurant in a Melbourne suburb and after they are split into teams, must feed 100 hungry diners.

It's the first Mystery Box of the season and contents include cherries, coriander, Manuka honey, black vinegar, taro, chicken feet, spring onions and galangal.

Today the chefs compete in a MasterChef Reverse auction, bidding for ingredients from four different categories to create a dish that will win them immunity.
