Goal (Australian rules football)

The rules were first formed by the Melbourne Football Club, chaired by Tom Wills in 1859. The laws significantly predate the advent of a governing body for the sport. The first national and international body, the Australasian Football Council, was formed in 1905 to govern Australian Football. Since 1994, the rules for the game known as Australian football have been governed by the AFL and the organisation's Laws of the Game committee.

18 players are permitted to take the field for each team, with an additional four players on an interchange bench (although this number often varies in exhibition and practice matches). The equipment needed to play the game is minimal. As in other kinds of football, players wear boots with stops (known as "cleats" or "studs" in some regions) in the soles, shorts, and a thick, strong shirt or jumper known as a guernsey, normally sleeveless, although long sleeve jumpers are sometimes worn in very cold weather by some players.

Protective gear is minimal. Most players wear a mouthguard but only a very few wear a helmet, normally a bicycle style helmet with a soft outer covering, and only after medical advice, such as if they have been concussed numerous times. Some players, predominantly ruckmen, wear shin guards. All protective equipment must be approved by the umpires to ensure that it can not injure other players.

The game is played with an ellipsoid ball, on a grassed oval.

Four posts, aligned in a straight line, 6.4 metres apart from each other, are erected at either end of the oval. The size of the ground is not fixed, but is generally between 135-185m long and 110-155m wide. Lines are drawn on the field to mark

The game is a fast-paced combination of speed, athleticism, skill and physical toughness. Players are allowed to tackle the player with the ball and impede opposition players from tackling their teammates (known as shepherding), but not to deliberately strike an opponent (though pushing the margins of these rules is often a substantial part of the game). Like most team sports, tactics are based around trying to get the ball, then – through a combination of running with the ball, hand-passing (punching the ball from the open palm of the other hand) and kicking – to deliver it to a player who is within range of goal. Because taking a mark entitles the player to a free kick, a common tactic is to attempt to kick the ball on the full (without bouncing) to a teammate who is within kicking range of goal. In this situation, packs of players often form around the goal square, and the opportunity arises for spectacular marks in which players launch themselves off opponents' backs to mark the ball, high in the air. This particular skill is highly regarded as a spectacle, and an annual "Mark of the Year" is awarded at the end of a season.
