Every season of The X Factor ever, ranked from best to worst by thousands of votes from fans of the show. The best seasons of The X Factor!

Part 1 of the audition discovered some truly ""xtraordinary, xceptional and xciting"" Australian singing talent. Thousands of talented, ambitious and in some cases deluded contestants paraded past the three judges, who worked together as a majority rules selection panel. Contenders will now audition for one of three categories - solo artists 16-24, solo artists 25 plus, and vocal groups. Of the thousands of hopefuls, only 30 contestants will be chosen in each of the three categories.   This episode's auditions were from Melbourne.
