Australian Rules Football Ball Views
Australian rules football, officially known as Australian football,[1] also informally known as football, Aussie rules or (colloquially) as footy[2] (and in some regions called—erroneously—AFL, after the Australian Football League, the only fully professional Australian rules football league) is a sport played between two teams of 22 players (18 on the field, 3 interchanges and 1 substitute) on either an Australian rules football ground or a modified cricket field.
The most prestigious competition is the Australian Football League (AFL), which culminates in the annual AFL Grand Final; currently the highest attended club championship event in the world. Australian football is governed by the AFL Commission which also runs the AFL competition and the rules are decided by the AFL's Laws of the Game Committee.
There is no offside rule nor are there set positions in the rules; unlike many other forms of football, players from both teams may disperse across the whole field before the start of play. However, a typical on-field structure consists of six forwards, six defenders or backmen and six midfielders, usually comprised of two wingmen, one centre and three followers, including a ruckman, ruck-rover and rover. Only four players from each team are allowed within 50 metres (55a yd) of the centre square before every centre bounce, which occurs at the commencement of each quarter, and to restart the game after a goal is scored. There are also other rules pertaining to allowed player positions during set plays (that is after a mark or free kick) and during kick-ins following the scoring of a behind.
A game consists of four quarters and a timekeeper officiates their duration. In professional Australian football, quarters are 20 minutes plus time on. Time on refers to clock being stopped when the ball is out of play, meaning that an average quarter could last for 27 to 31 minutes. At the end of each quarter, teams change their scoring end.
