The X Factor Australia 2005
The X Factor Australia: The Australian version of The X Factor mirrors the UK format. The show aims to find talent over the age of fourteen in four categories: Under 25 Boys, Under 25 Girls, Over 25s, and Groups. In the original 2005 series the categories were the same except the under 25 categories for male and female were in one category. In 2011, a new format was introduced to the show where the new minimum age for contestants is aged 14.
