Finale Night - Poh and Julie competed against each other in three rounds consisting of a Taste Test, an Invention Test and a Pressure Test. Points would be earned for each test, with the winner decided based on the final tally after the three tests.

The top 50 began with a barbecue challenge, with the freedom to cook whatever they wanted. The 10 worst performers were sent into a pavlova pressure test led by Donna Hay. The 5 contestants who produced the worst pavlovas were eliminated from the competition.

The remaining contestants were asked to prepare their signature dish. In a first for MasterChef Australia the contestants did the judging, with the men voting for their favourite dish from the women, and vice versa. The top 7 vote-getters (4 women, 3 men) were then put into a beef wellington pressure test, with the best man and woman progressing directly to the top 24. The winners, Claire and Jimmy, were the first pair to advance to the Top 24.

The 10 contestants who performed worst in Tuesday's signature dish challenge were split into 5 groups of 2 and given 7 hours to drive out to local farms, collect fresh produce, and return to the MasterChef kitchen to prepare a main and a dessert. One contestant, Andrea, found the challenge difficult, and realised that MasterChef was not for her; her withdrawal from the competition forced her partner in the challenge, Philip, to prepare both dishes on his own. Despite this setback, he and 4 others kept their spots in the competition, while 5 contestants were eliminated.
