Changes To Format
Kyle Sandilands, Ian Dickson, and Marcia Hines returned as judges, however long term judge Mark Holden left to pursue other interests. Andrew G was temporarily absent while he prepared for his wedding and Ricki-Lee Coulter is acting as a new back-stage host. The London auditions featured guest judges Tina Arena and Darren Hayes.
Also for the second time on an Idol contest, the format for eliminations in the Top 12 round will be different. In the new result nights, the bottom 3 of the week will be announced first and the voting line will be opened again for viewers to vote for their favourite in the bottom 3. Music Idol, the Bulgarian version of Idol, were the first to use this new format in their second season. New Zealand Idol season 3 used a similar format for the second week of the finals, but dropped it afterwards.
