The Australian Athletics Championships or Australian Open Track and Field Championships are held annually to determine Australia's champion athletes in a range of athletics events. The championships are the primary qualification trial for athletes wishing to compete at the Olympic Games, Commonwealth Games or World Championships. The event is conducted by Athletics Australia.
The championships were first held in 1890 under the name Inter Colonial Meet. The competition was staged at Moore Park in Sydney on 31 May 1890. Teams from the Australasian colonies of New South Wales, Victoria, Queensland and New Zealand competed in the first formalised Australasian Athletics Championships meeting in 1893.
A New Zealand team continued to compete in this event until the 1927/28 event. At the next championships in 1929/30, women's events were included for the first time.
In 1933, the women began conducting their own championships, with a wider range of events. Except for occasional combined championships in 1936, 1972 and 1976, the separation of men's and women's championships continued until the 1977/78 event.
The full range of Olympic events is not usually conducted at the National Championships. During the 2007/08 season the following championship events were held separately:
The most successful athletes at the Championships have been throwers Gael Martin and Warwick Selvey who won 20 and 19 championships events, respectively.
