Contestants compete in the Quarter Final challenge using ingredients chosen by loved ones, cooking off for a place in the Semi Final.

The top 24 contestants enter the kitchen for their first mystery box challenge to create a dish with ingredients chosen by 2015 MasterChef Australia winner, Billie McKay.

The top four contestants cook-off for immunity. The winner must then try and out-cook guest chef Victor Liong from Lee Ho Fook.

A fete in Negella Lawson's name is held and the contestants are split off into three teams. The teams must prepare one savoury dish and two sweet dishes to sell, with all proceeds donated to the Royal Children's Hospital.

The bottom four bid for produce as the judges auction them off for use in the elimination round.

The bottom three contestants face-off in the elimination pressure test. They must recreate two of guest chef Ross Lusted's signature dishes in two hours.
