The contestants are split into teams of four in a relay challenge as each member has 15 minutes to cook and only 45 seconds to hand over to the next cook in the relay.

Contestants will be working in teams to build an edible art installation in a specially constructed greenhouse. With just 7 hours to impress the judges which team will be safe from elimination?

Your favourites are back for another crack at the coveted MasterChef title. Up for grabs tonight is this season's only immunity pin and joining them all week is chef extraordinaire, Gordon Ramsay.

The top 24 contestants enter the kitchen for their first mystery box challenge.

The three best performers from the invention test now compete for a chance at immunity. Will our amateur cook have what it takes to out-perform one of Australia's best chefs?

The heat is on. A fresh group of home cooks from around the country will eagerly tackle challenges that will see one of them take home the title and $250,000.
