What is the maximum number of players each team is allowed in Australian rules football?

Australian rules football, officially known as Australian football, or simply called Aussie rules, football or footy, is a contact sport played between two teams of eighteen players on an oval-shaped field, often a modified cricket ground. Points are scored by kicking the oval-shaped ball between the opposing goal posts (worth six points) or behind posts (worth one point). The team with the highest score at the end of the match wins unless a draw is declared.

The sport's origins can be traced to football matches played in Melbourne, Victoria in 1858, inspired by English public school football games. Seeking to develop a game more suited to adults and Australian conditions, the Melbourne Football Club published the first laws of Australian football in May 1859, making it the oldest of the world's major football codes.
