The Grammy-nominated former Jonas Brothers band member will take up the fourth chair when the talent show returns for season 7 in 2018.
Jonas, 28, now the frontman of band DNCE will sit alongside fellow coaches Delta Goodrem, Kelly Rowland and Boy George.
This won't be the Cake By The Ocean singer's first experience with the show. He starred on The Voice US as a mentor for Adam Levine's team.
“I couldn’t be more excited to be a part of a massive show like The Voice, especially getting to do it all in Australia where the fans are amazing,” Jonas said. “I had a taste of the show in the US this year, so now I have the knowledge to take #TeamJoe all the way in 2018.”
