The ant fauna of Australia is large and diverse. As of 1999, Australia and its external territories represent 1,275 described taxa (subspecies included) divided into 103 genera and 10 subfamilies. No publication since 1999 has estimated the current diversity of Australia's ant fauna, although it has considerably increased in size as the total amount of subfamilies in Australia today is around twelve. Very few species in the country are known to be invasive.
