- Australia were the winners of the 1966 Quidditch World Cup (Pm).
- Chaser Royston Idlewind later served as the International Director of the ICWQC from 1971 to 1974 (Pm).
- Quidditch came to Australia some time in the eighteenth century and has become very popular, not least because of the large areas of uninhabited outback where Quidditch can be played without Muggle notice. Australian teams are known for both speed and showmanship (QA8).
Although Australia was a participant in Quidditch World Cup tournaments, there are not any Quidditch or other wizarding sports listed on its Wikipedia page (Wikipedia).
