The twelfth season of The Voice began airing on 6 August 2023. In March 2023, it was announced Seven Network had once again picked up the series for its twelfth season, set to broadcast in 2023. At the same time, it was announced that Jessica Mauboy, Rita Ora, and Guy Sebastian would all return as coaches. Jason Derulo debuted as a coach, replacing Keith Urban, who left the show for personal reasons. Sonia Kruger also returned as host.
With Keith Urban's departure as a coach, the twelfth season is the first to not feature any of the original coaches from the show's inaugural season.
Similar to the previous two seasons, the finale was pre-recorded and the winner was determined by a viewer poll. Tarryn Stokes was declared the winner, marking Rita Ora's third and final win as a coach (her first win occurred on the generations version of the show). Also, with Stokes' win, Ora became the third coach (after Seal and Delta Goodrem) to win two consecutive seasons in the Australian franchise of The Voice. Moreover, with Ora's win, she tied with Delta Goodrem for having the most wins as coaches on The Voice Australia.

In the blind auditions, the coaches complete their teams with 12 members each. Each coach can block another two times, and the coach who is blocked is unable to pitch for the artist. Like last season, a coach can block at any time, even during their pitch, as long as the blocker turned their chair. However, this season, coaches are allowed to block before a coach turns their chair. Also, this season axed the Battle Pass, which was introduced in the previous season.
The callbacks aired on 28 and 29 August. Coaches form four groups of three, with one going straight home, one going straight through to the battles, and one going to the ultimate callbacks for a final decision before the battles.
The ultimate callbacks aired on 3 September. Coaches form two groups of two from the artists that did not advance from the callbacks nor were eliminated. In a make-or-break sing off, one from each group advances to the battles, while the other is eliminated.
The Battles aired on 10 September and 17 September. In the battles, coaches are to cut their team to 2 artists by pairing their artists to sing the same song as a duet.
Team Guy and Jason performed on the first night of battles and Team Jess and Rita performed on the second night.
In the Singoffs, coaches pick one of their battle winners to go straight through the Semifinals. Then the remaining artists must Singoff for the last remaining spot on their team to advance to the semifinal.
The Semifinal aired on 24 September. The 8 remaining artists sing different songs for a place in the Grand Final. At the end of the episode, coaches are only allowed to pick one artist from their team to advance to the Grand Final.
The Grand Finale was broadcast on 8 October 2023. Each artist performed a solo song and a duet with their coach. Similar to the last three seasons, this was the only episode of the season where the results were determined by public vote and not by the coaches. Tarryn Stokes was declared the winner, marking Rita Ora's second consecutive win as a coach and tied with Seal, Delta Goodrem, and Kelly Rowland with the most wins on the Australian version of The Voice.
