In Australian rules football, a ruckman is typically a tall and athletic player who contests at centre bounces and stoppages (such as boundary throw-ins and ball-ups). The ruckman is one of the most important players on the field. They are often key to coaching strategy and winning centre clearances which result in the most goal kicking opportunities (inside 50s).

The role of the ruckman in Australian rules is similar to a lock in rugby union contesting a line-out. The key differences are that with the exception of boundary throw-ins, the ball is almost always thrown straight up high into the air rather than horizontally, so in this respect, the ruckman is similar to a basketball centre. The ruckman needs to be able to control the ball by palm tap or fist with outstretched arms. Unlike rugby, the ruckman must rely on his vertical leap and is not assisted by teammates and Australian football rucking often involves vigorous mid-air collisions with the opposing ruckman.

With no offside or knock on rules, the ruckman can tap the ball in any direction. Before a bounce down or ball up, ruckmen confer with the onballers (rovers and ruck-rovers) to pre-determine the direction of the tap so that they can position themselves to best receive it to the team's advantage.

Australian rules football, officially known as Australian football,also called football, footy or Aussie rules (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 18 players on the field on either an Australian rules football ground, a modified cricket field or another modified sports venue.

The objective of the game is to score points by passing the ball through the team's goal. The main way to score points is by kicking the ball between the two major goal posts. The team with the higher total score at the end of the match wins unless either a draw is declared or a tie-break is used.

During most play, players may position themselves anywhere on the field and use any part of their body to move the ball. The primary methods are kicking, handballing and running with the ball. There are rules on how the ball can be handled: for example, players running with the ball must intermittently bounce or touch it on the ground. Throwing the ball is not allowed and players must not get caught holding the ball. Possession of the ball is in dispute at all times except when a free kick is paid. A distinctive feature of the game is the mark, where players anywhere on the field who catch a ball from a kick (with specific conditions), are awarded a free kick. Australian rules is a contact sport, in which players can tackle using their hands or use their whole body to obstruct opponents. Dangerous physical contact (such as pushing an opponent in the back), interference when marking and deliberately slowing the play are discouraged with free kicks, distance penalties or suspension, depending on the seriousness of the infringement. Frequent physical contests, spectacular marking, fast movement of both players and the ball and high scoring are the game's main attributes.

Australian people, or simply Australians, are the citizens of Australia. Australia is a multi-ethnic nation, and therefore the term "Australian" is not a racial identifier. Aside from the Indigenous Australian population, nearly all Australians or their ancestors immigrated within the past 230 years. Colloquial names used to refer to Australians include Aussies, and Antipodeans.

The mainstream Australian culture (occasionally defined as the Anglo-Celtic culture), is a Western culture largely derived from the traditions of Western European migrants beginning with the early settlers from England, Scotland, and Ireland. The populations of Sydney, Melbourne and the other major cities are different from the demographics of rural Australia as a result of the differing migration patterns.

The earliest accepted timeline for the first arrivals of indigenous Australians to the continent of Australia places this human migration to at least 40,000 years ago most probably from the islands of Indonesia and Papua New Guinea.

Football refers to a number of sports that involve, to varying degrees, kicking a ball with the foot to score a goal. The most popular of these sports worldwide is association football, more commonly known as just "football" or "soccer". Unqualified, the word football applies to whichever form of football is the most popular in the regional context in which the word appears, including association football, as well as American football, Australian rules football, Canadian football, Gaelic football, rugby league, rugby union and other related games. These variations of football are known as football "codes".

Various forms of "football" can be identified in history, often as popular peasant games. Contemporary codes of football can be traced back to the codification of these games at English public schools in the eighteenth and nineteenth century. The influence and power of the British Empire allowed these rules of football to spread, including to areas of British influence outside of the directly controlled Empire, though by the end of the nineteenth century, distinct regional codes were already developing: Gaelic Football, for example, deliberately incorporated the rules of local traditional football games in order to maintain their heritage. In 1888, The Football League was founded in England, becoming the first of many professional football competitions. In the twentieth century, the various codes of football have become amongst the most popular team sports in the world.
