The ninth season of The Voice began airing on 24 May 2020. For the first time in the show's history all of the coaches returned: Delta Goodrem for her eighth, Kelly Rowland and Boy George for their fourth and Guy Sebastian for his second. Following the exit of Sonia Kruger, Darren McMullen, who hosted the first four seasons, returns with new co-host, Renee Bargh.

Chris Sebastian from Team Kelly won the competition on 19 July 2020, marking the second All-Star to win, as well as Kelly Rowland's second and final victory as a coach in her fourth, and final, season on The Voice Australia.

Coaches and hosts

Right after the end of the eighth season, the series was renewed for a ninth season and was announced that all coaches would return the new season. Darren McMullen, who exited as host following the conclusion of the fourth season, returns as host, alongside new co-host Renee Bargh, following the exit of Sonia Kruger.

In June 2020 the Sydney Morning Herald reported that Marcia Hines and The Veronicas were to fill in as guest mentors for Rowland and Boy George respectively, who will be mentoring their acts remotely from the US and UK because of travel restrictions in place due to the COVID-19 pandemic.

Guy turned his chair for Wolf Winters despite already having a full team. Producers allowed him to keep Wolf as the 13th member of his team with the condition of losing two artists in a three-way battle in the next round.

Battle rounds The Battle rounds started on 21 June. The coaches can save two losing artists from any team, including their own. Contestants who win their battle or are saved will advance to the playoffs.

Delta could not decide on a winner between Janie and Matt. With approval from the producers, she suggested they become a duo, and both artists agreed. The duo adopted the stage name "Goldi".

Playoffs The Playoffs started on 5 July. In the Playoffs, each coach pairs two of their artists together, with each artist singing an individual song following a theme. After all of their team's playoffs were done, the coaches chose one of their losing artists as a wildcard. The top 20 contestants who win their Playoff or are chosen as a Wildcard move on to the Showdowns. Due to COVID-19 and travel restrictions, Kelly and George mentored their artists remotely, with Marcia Hines and The Veronicas filling in as guest mentors respectively. Artists Caleb Jago-Ward from Team George and Ella Monnery from Team Kelly were unable to continue on the competition also due to travel restrictions, being stuck in New Zealand. Coaches George and Kelly were allowed to bring back an eliminated Battle loser to fill in for Caleb and Ella, George choosing Elyse Sene-Lefao and Kelly chose Jimi the Kween.
