Scoring
A ball kicked over the goal line between the two larger goal posts by an attacker (without being touched) is a goal and scores six points. The ball is returned to the center circle for a "ball-up." There is no possibility of an "own goal" as in soccer.
If the ball passes over the goal line between the behind posts by any other means, then it is a behind, and it scores 1 point. If the ball hits the goal post, a behind is scored. This is regardless of where the ball goes after hitting the goal post, e.g., back into the field of play, through the goals or whatever. The ball is kicked back into play from within the goal square, usually by the opposing fullback.
If the ball hits a behind post without bouncing it is deemed "out on the full" and the opposing team takes a free kick from next to the behind post. If the ball bounces and hits the behind post then the ball is thrown into play again by the boundary umpire from next to the behind post (see (b) under "Starting and Restarting Play" below). In either case, no points are scored.
The team scoring the most points wins the game. The match is considered drawn if points are equal.
If a finals match or the Grand Final ends in a draw, an estra 10 minutes is played with the sides swapping goal ends after 5 minutes. Regardless of who scores when, the full 10 minutes is played out, unlike estra innings in baseball in which whoever scores first wins the game.
