And now the Aussie singing sensation has opened up about her decision to move on from her role as coach on the show, on which she featured from its first season in 2012 up until last year, taking a brief hiatus in 2014.
In an interview with Stellar magazine this week, the Born To Try hitmaker explained that it "was time" for her to focus on "other projects".
"It felt like the right moment for me to lean into my creativity," she told the publication.
One of the first projects Delta Goodrem announced was a partnership with Channel Nine to launch her own production company, Atled Productions.
She also released her seventh studio album, Bridge over Troubled Dreams, this year, alongside a book of the same title, which talks about the meanings behind the songs on her new album and also charts her two-year struggle to speak again after battling cancer.
The Voice ran for nine seasons on Channel Nine from 2012 until 2020, before it made the move to Channel Seven in 2021.
And it soared in the ratings, with host Sonia Kruger - who also moved to Channel Seven for the role - saying the show had "found its heart and soul again".
While each episode of the most recent season - which saw Bella Taylor Smith crowned the winner - peaked at over one million viewers, former coach Delta has admitted she only watched "a bit here and there".
"I was cheering on the team and all the crew who I’ve worked with over the years; the camera guys and the entire production. They always do an absolutely sublime job," she told Stellar.
There have been some rumours that Delta might eventually return to The Voice, with New Idea recently reporting that while Channel Seven would love to secure the current star-studded lineup of coaches for next season, they were struggling to lock in UK songstress Rita Ora for another year.
“Rita could prove to be an issue,” their source claimed. “She’s no longer in Australia, and enjoying her personal life with a new boyfriend. She’s happy - her return is currently not guaranteed.”
Channel Seven is allegedly “desperate” to get Delta to fill her seat and come back to the show, with Guy Sebastian said to be “instrumental” in luring her back.
“Delta’s return to Channel Seven can’t be ruled out," the insider added.
