The first season of The Voice, the Australian reality talent show, premiered on 15 April 2012 and concluded on 18 June 2012, with Karise Eden being crowned as the winner.
On 29 May 2011, it was reported in The Daily Telegraph that the Nine Network would broadcast The Voice in late 2011. However, two months later, they reported that the show would now air in early 2012, and that the Nine Network were in talks with signing at least one international artist (especially an American) to lead its panel of coaches on the show, which were rumoured to be Christina Aguilera, George Michael, Usher, Pink and Gwen Stefani. In September 2011, the Herald Sun reported that the Nine Network were planning to sign Australia's Got Talent judge Dannii Minogue as one of the coaches. Anthony Callea, Vanessa Amorosi and former Pussycat Dolls member Ashley Roberts all publicly expressed interest in coaching roles, however Delta Goodrem, Keith Urban, Seal and Joel Madden were ultimately confirmed as the four coaches for the first season.
Additionally, Ricki-Lee Coulter (with Seal), Darren Hayes (Goodrem), Megan Washington (Urban) and Benji Madden (with brother Joel) paired up with the coaches as mentors for their contestants.
Darren McMullen was announced as the host of the program in January 2012. Faustina Agolley was announced as the social media correspondent during the live shows in May 2012.
