Australian Football is a sport played between two teams of eighteen players on the field of either an Australian football ground, a modified cricket field, or a similarly sized sports venue. The main way to score points is by kicking the ball between the two tall goal posts. The team with the higher total score at the end of the match wins.
Conceived in 1857 as a winter game to keep cricketers fit during off-season, Australian Football has evolved over time. In 1880, the current Official ball was invented by T.W. Sherrin after he was given a misshapen rugby ball to fix. The rugby ball was elongated, and used to wear heavily on the ends of the ball. Tom created a new shape and developed a pattern that made the ball rounder on the points. The ball was still oval in shape, which allowed the ball to bounce more evenly and easier to kick.
The Australian Football League appears to be the authority on the Laws of Australian Football, wherever it is played. Part C, Section 4 of the Laws of Australian Football 2008 provides the details.
