Australian rules football

Australian rules football, also called Australian football or Aussie rules, or more simply footy or just football, is a contact sport played between two teams of 18 players on an oval field, often a modified cricket ground. Points are scored by kicking the oval ball between the central goal posts (worth six points), or between a central and outer post (worth one point, otherwise known as a "behind").
