The show was hosted by David Koch, with the judging panel consisting of Jonathon Welch, Iva Davies, Charli Delaney, and George Torbay.
The format of the show is based on an idea by Swedish singer and chorister Caroline af Ugglas which has been previously adapted by many countries, most notably as Clash of the Choirs in the United States.
[1] The series involves 16 community choirs of up to 40 members from around Australia competing against each other in a knockout competition that sees them performing songs from many different musical genres.
After that, the two choirs remaining are left to sing their Battle Tunes, one straight after the other, and the judges decide who gets promoted to the next leg of the competition and who gets eliminated.
Vox Synergy sang of the Sarah McLachlan song "Angel, while the University of Newcastle Chamber Choir won with their arrangement of Queen's "Bicycle Race", and Sting's 'Straight to My Heart'.
