Australian Rules Football – Rules, Positions & Field Dimensions
Australian rules football is a fast-moving game played on an oval-shaped field. This guide explains the rules, traditional player positions, field markings, scoring and common umpire decisions in one place. It is designed for spectators, students, parents and players looking for a practical reference.
In traditional Australian rules football, each team fields 18 players on an oval. A goal, kicked between the two taller central posts without being touched, scores 6 points; a behind scores 1 point. Players move the ball by kicking, handballing or running while bouncing or touching it to the ground at required intervals. AFL competition rules and team interchange arrangements can change, and junior or community formats may differ.

Australian Rules Football Oval Diagram
This original simplified illustration identifies the boundary, centre square, centre circle, 50-metre arcs, goal squares and goal posts. It is schematic, not a scale drawing or a field-construction plan.
Diagram note: Four posts stand at each scoring end: two taller goal posts in the middle and two shorter behind posts outside them. The dashed curves indicate the 50-metre arcs. Oval shapes and sizes vary between grounds.
Australian Rules Football Field Dimensions and Markings
Unlike basketball or tennis, Australian rules football does not use one fixed overall playing-field size. The following are common dimensions used in Australian rules football; specific venue requirements and competition regulations should be checked separately.
| Field feature | Typical measurement or explanation |
|---|---|
| Oval length | Often approximately 135–185 m |
| Oval width | Often approximately 110–155 m |
| Centre square | 50 m × 50 m |
| Centre circle | Typically 3 m in diameter |
| 50-metre arcs | Marked 50 m from the centre of each goal line |
| Distance between goal posts | 6.4 m |
| Goal post to adjacent behind post | 6.4 m |
Dimensions may be adapted for smaller community grounds and junior competitions. The field ranges above are indicative rather than universal legal limits.
The 18 Traditional Australian Rules Football Positions
Australian rules football has 18 traditional on-field positions, commonly arranged across defence, midfield, ruck and attack. Modern teams rotate and use tactical roles that do not always match these labels exactly.
| Position (number on field) | Typical responsibility |
|---|---|
| Back pocket (2) | Defend close to goal, cover small forwards and help clear the ball. |
| Full-back (1) | Defend near the opposition goal, often against a key forward. |
| Half-back flank (2) | Intercept, rebound and move the ball out of defence. |
| Centre half-back (1) | Organise defence and contest marking situations. |
| Wing (2) | Provide width, run between defence and attack and link play. |
| Centre (1) | Contest midfield play and help win possession. |
| Ruck-rover (1) | Work around stoppages and help win clearances. |
| Rover (1) | Gather loose balls and distribute possession around contests. |
| Ruck (1) | Contest ruck contests and tap the ball to teammates. |
| Half-forward flank (2) | Link midfield to attack and create scoring opportunities. |
| Centre half-forward (1) | Present as a key marking target and help direct attacking play. |
| Forward pocket (2) | Apply forward pressure and create scoring chances near goal. |
| Full-forward (1) | Play close to goal and convert scoring opportunities. |
The numbers add to 18. The names describe conventional starting roles, not fixed areas: unlike netball, Australian rules players can generally move around the ground, subject to applicable starting-position and other competition rules.
Australian Rules Football Rules Explained
How does a match start?
Play starts with a centre bounce or ball-up, depending on the competition and circumstances. The umpire restarts play after goals and at certain stoppages. Modern AFL-specific restart procedures can differ from other competitions.
How do players move the ball?
Players can kick or handball the ball. A handball is made by striking the ball with a clenched fist while holding it in the other hand. Players cannot legally throw the ball. When running with possession, a player must bounce or touch the ball to the ground at least once every 15 metres.
What is a mark?
A mark is generally awarded when a player catches a ball directly from a kick that travels at least 15 metres, without another player touching it or the ball touching the ground. A player awarded a mark normally receives a set kick. Other conditions and exceptions apply.
What is holding the ball?
Holding the ball is a free-kick decision involving a player in possession who is legally tackled and fails to meet the relevant requirements for disposing of the ball. Whether the player had prior opportunity and made a genuine attempt matters under the applicable interpretation. Not every tackle results in a free kick.
What is a legal tackle?
Tackling is permitted within the rules, but dangerous tackles and contact that is too high or too low may be penalised. A tackle must not be executed in a prohibited or dangerous manner. Umpires judge the circumstances of each contest.
What is a free kick?
A free kick can be awarded for infringements such as holding the ball, a high tackle, pushing in the back, illegal disposal, holding an opponent or certain prohibited contact. A player awarded a free kick may kick or handball, subject to the applicable rules.
What is the 50-metre penalty?
In AFL football, a 50-metre penalty can advance the position of a free kick or mark after certain infringements, such as interfering with an opponent's ability to take the kick. Different leagues or age groups may apply different penalty distances.
What happens when the ball goes out of bounds?
Depending on how the ball crossed the boundary and which rules apply, play may restart with a boundary throw-in or a free kick. Deliberate or insufficient intent to keep the ball in play can be penalised under the applicable interpretation.
How Scoring Works: Goals and Behinds
| Score | Points | How it happens |
|---|---|---|
| Goal | 6 | The attacking team kicks the ball completely over the goal line between the two central posts, without disqualifying contact. |
| Behind | 1 | For example, the ball crosses between a goal post and a behind post, or crosses the goal line in a way that does not qualify as a goal. |
Example: A team scoring 10 goals and 8 behinds records 10.8 (68), because (10 × 6) + 8 = 68. The team with the higher points total wins, subject to any competition-specific result rules.
How Long Is an Australian Rules Football Game?
In the AFL men's competition, matches are played in four quarters, traditionally 20 minutes of playing time per quarter plus time-on. The actual elapsed time is longer because the clock is stopped for certain events. Junior, community and other elite competitions may use different quarter lengths and timekeeping arrangements.
Australian Rules Football vs Rugby and Soccer
Australian rules football uses an oval-shaped field, four scoring posts at each end, marks from qualifying kicks and a combination of kicking and handballing. Rugby and soccer have different scoring systems, fields, possession rules and methods of restarting play. Despite the word “football”, these are distinct sports.
Equipment and Safety
Players use an oval-shaped football, appropriate boots and a suitable playing surface. Football sizes vary by age and competition. Protective equipment and participation rules should follow the relevant league or club's guidance. Coaches and players should prioritise safe tackling and concussion protocols.
Frequently Asked Questions
How many players are on the field?
There are 18 players from each team on the field in traditional AFL football. Interchange and substitute arrangements depend on the current competition rules.
How many points is a goal?
A goal is worth six points. A behind is worth one point.
Can players run with the ball?
Yes. A player carrying the ball must bounce or touch it to the ground at least once every 15 metres.
Can players throw the ball?
No. A legal handball is struck with a clenched fist; throwing is an infringement.
Is every football oval the same size?
No. Grounds differ in length and width. Standard field markings are used, but the overall oval dimensions vary.
What is the difference between a goal and a behind?
A goal scores six points and must satisfy the rules for a goal between the central posts. A behind scores one point and can occur in several ways, including crossing between a goal post and behind post.
Are senior rules the same as junior footy?
Not necessarily. Junior and community competitions can modify team sizes, field sizes, match lengths, tackling and other rules.
What does 'prior opportunity' mean?
It is an important consideration in certain holding-the-ball decisions. Broadly, it concerns whether the player had an opportunity to dispose of the ball before being legally tackled. The detailed interpretation should be checked against current rules.
