For this season of the Voice, the show replaced the usual 'Battles' round with 'The Callbacks', which is a twist to the show first adopted by the tenth season of The Voice Australia. The Callbacks aired on 15 October. In this round, each coach brought in a mentor for their team. David Guetta, MNEK, Tom Grennan, and James Arthur were invited by will.i.am, Anne-Marie, Tom Jones, and Olly Murs, respectively.
