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

The contestants are given a Mystery Box challenge and are then tasked with taking over the QANTAS First Lounge kitchen at Sydney Airport.

The teams' next challenge is to prepare a three-course lunch service at the Merivale Felix restaurant in Sydney.

The five contestants with the most impressive dishes from the previous challenge must compete in an immunity challenge; Andy and Jock teach a MasterClass.

The contestants are given a mystery box containing several exotic Korean ingredients.

The fierce battle for the immunity pin sees Christine Manfield as a guest judge.
