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

The winners of the invention test and mystery box face off against each other in round one, with the winner going up against a professional cook in round two, and fast tracking their place to finals week.

A fast pass for the finals is the prize for four contestants as they cook a variety of grape-based dishes in Napa Valley.

The contestants compete in a time auction elimination challenge to bag themselves a spot in the final seven.

The competition goes to California for the week, where, armed with only a map, contestants track down mystery box ingredients from local shops.

MasterChef Australia 2016 runner-up Matt Sinclair is on hand to mentor contestants in a pop-up restaurant team challenge.
