An 18-a-side game that is a cross between Gaelic football, rugby, and soccer, and is unique to Australia, although association and rugby football are also played there. Each side is placed in 5 lines of 3 persons each. Three players follow the ball all the time. The 2 goalposts, at each end, are 6 m/19 ft high and 6.4 m/21 ft apart. On either side are 2 smaller posts. The football is oval, and weighs a little more than a rugby ball. A goal (6 points) is scored when the ball is kicked between the goalposts, if it is not touched on the way. If the ball passes between a goalpost and one of the smaller posts, or hits a post, the score is a `behind', or one point. There are no scrums, line-outs, or off-side rules. A player must get rid of the ball immediately on starting to run, by kicking, punching or bouncing it every 10 m/33 ft. No tackling (as in rugby) is allowed. This code originated on the Australian goldfields in the 1850s.
