The series sees a range of talented singers (solos and groups) perform in front of the biggest judging panel Australia has ever seen. The 100 will be made up of great singers and industry professionals with big voices and even bigger opinions. If any of The 100 like what they hear, they can stand up, join in and sing along. The greater the number that join in, the higher the act's score. Who can get them ALL on their feet singing along? The urge to join in at home will be irresistible.
