The 24 contestants enter the MasterChef kitchen and are greeted by legendary chef Gordon Ramsay; when they get over the shock he tells them will be here for the entire week to mentor them through the first stage of the competition.

Matt Stone and Jo Barrett from Oakridge Wines mentor a service challenge, with the teams cooking a savory or sweet menu; one team faces the pressure test.

Contestants must cook a savory pie and sauce in round one of an Australian-themed pressure test; the bottom four must create a dish celebrating what Australia means to them.

It's day three of Gordon Week and the winning team from yesterday's service challenge are back to cook; today, the challenge is a Round Robin Relay.

The mystery box ingredients are decided by the luck of the draw, with lottery balls corresponding to 25 ingredients.

Contestants are challenged to cook three pumpkin dishes in 90 minutes for immunity.
