Team George & Team Kelly perform on the first night and Team Delta & Team Guy perform on the second night. At the end of each episode, the coaches choose three out of their four artists to advance to the Live Top 12.[4]
With the eliminations of Jack Vidgen, Chynna Taylor, and Mitch Paulsen, Guy Sebastian had no more contestants left on his team, making this the fourth season in the Australian version of the franchise where a coach did not have a contestant in the Grand Finale.
