From seasons 1 to 7, the judging panel consisted of four primary judges: Todd McKenney, Helen Richey, Paul Mercurio and Mark Wilson. At the start of season 8, Mercurio left the judging panel. Before the eleventh season began, Wilson was dumped by the Seven network and replaced by Joshua Horner. McKenney, Richey and Horner have made up the primary judging panel since 2011. Kym Johnson who comes from the American version of the show, and Adam Garcia join the judging panel in 2013. In 2015, Bruno Tonioli, who comes from both British and American versions, replaced Garcia as a judge for the first three weeks before leaving just three judges for the rest of the season.
