Australian rules football (or Aussie rules/footy) is a dynamic contact sport where two teams of 18 players compete on an oval field, scoring six points for a goal kicked between the central posts and one point for a "behind". Its distinctive gameplay features the mark, which grants a player unimpeded possession for cleanly catching a kicked ball, alongside running, handballing, and tackling, with strict rules against throwing. The sport originated in Melbourne in 1858, inspired by English public school football, and the Melbourne Football Club published the first official laws in May 1859 following a letter from cricketer Tom Wills. It is Australia's most-attended sport, with the professional Australian Football League (AFL) being the nation's wealthiest sporting body, culminating in the AFL Grand Final at the 100,000-capacity Melbourne Cricket Ground. Governed by the AFL Commission, the sport is also played at amateur levels in many countries, showcasing its global reach.
