A captain of an Australian rules football team, sometimes known as a skipper is a player who, during the course of a match and off the field, has several additional roles and responsibilities over and above those of a regular player.
They are second to the coach and an onfield leader who has various roles including to inspire the players and sometimes address umpires and the media.
When a coach appoints multiple captains, the following captaincy roles may be appointed.co-captain (is multiple captains)
vice-captain (is second to the captain)
deputy vice captain (is used only when both captain and vice captain are injured)
Before the start of a match, a coin toss between the captains is used to determine which end of the ground each team will kick to. The away captain calls the coin toss, and the winning captain makes the choice of end. The decision usually depends on the weather conditions and the weather forecast, particularly the direction and strength of the wind, which can give a significant advantage to a team.
Before the game and during the quarter and half time breaks, a captain will be asked by the coach to address the players in a huddle after the coach address. Whereas the coach address typically discusses strategy and field positions, the captain's address is usually purely motivational.
The captain is the only player on the ground who is allowed to address an umpire to question or discuss a decision. Any other player who does so can be penalised or reported. A captain may also be reported if he becomes abusive.
The umpires will typically visit the rooms of each team before a game and introduce themselves to the captain and advise the captains on any rule interpretations that they will be strict on and what they will and won't tolerate on the field.
The captain will often take a particular role in media relations on behalf of the team.
Although not always, the captain may be asked to participate on the selection committee to determine which players do or do not make the squad.
The captain and the leadership group represents the playing group. If a player does something to the detriment of the playing group (such as inappropriate behaviour like taking drugs), then the captain will often act in the interests of the playing group and request that the club or league take appropriate action.
The captain of the team may request the game to be stopped for a head count, to determine whether or not the opposition team is fielding too many players.
It is tradition during a grand final that the captain and coach hold up the premiership cup before it is handed to the players. The captain is required to make a speech, including thanking the opposition team.
