The tenth series of the Australian cooking game show MasterChef Australia premiered on 7 May 2018 on Network Ten. Judges Gary Mehigan, George Calombaris and Matt Preston returned from the previous series, with Shannon Bennett as the contestants' mentor.
This series was won by Sashi Cheliah in the grand finale against Ben Borsht, on 31 July 2018.
Changes This season introduced a change in the Mystery Box Challenge. The winner will be going straight into the Immunity Challenge, which means they will not be cooking in the invention test and will be safe from the Pressure Test on the following day.
Week 10 featured the remaining contestants competing for a special "10-Year Superpower" apron, which works similar to an immunity pin and a Power Apron but allows the bearer to withdraw during any stage of any individual challenge up to tasting.
Contestants Top 24 The Top 24 were announced on 7–8 May 2018. Contestant Jo Kendray was a returning auditionee after two previous attempts to make it into the Top 24
