If you’ve watched an AFL match and then turned up to a local or junior game, you may have noticed that the number of players, field size and playing time can change quite a bit. The basic contest stays familiar, but Australian Rules Football uses several match formats to suit elite competition, community clubs and different age groups.
The standard format: 18 a side
The most recognisable version is the full-field game played by 18 players per team. That is the format used in the AFL and in many senior community competitions. Teams compete on an oval-shaped ground, move the ball by kicking or handballing, and score by kicking it between the goalposts.
With 36 players on the field, there is room for distinct roles without fixed positions. Forwards work to create scoring chances, defenders try to limit them, and midfielders contest the ball and link the two ends. Players can move around the ground, so a defender might push forward and a tall forward might help at a centre bounce. Interchange players allow teammates to rotate on and off the field; the number of available players and interchange rules depend on the competition.
At AFL level, a match is divided into four quarters, generally listed as 20 minutes plus time-on. Time-on stops the playing clock for certain delays, so a quarter takes longer than 20 minutes in real time. Local leagues can set different quarter lengths. Breaks between quarters and at half-time also vary by competition.
The same 18-a-side structure is used in men’s and women’s Australian football. The playing time, ground conditions and competition regulations may differ, but the central skills and scoring system are shared.
Shortened and junior matches
Not every match needs the full length of an elite senior game. Junior competitions commonly shorten quarters, adjust breaks or use other changes to make games manageable for younger players. The details are set by the league and can change with age group, local conditions and the number of players available.
Shorter games are not simply senior matches squeezed into less time. Junior rules may also limit contact, set expectations around tackling, or adjust the playing area and team numbers. These changes give developing players more chances to handle the ball and learn positioning without asking them to cover a full senior-sized ground for a full-length match.
There is no single nationwide junior duration that applies to every competition. If you’re planning to watch or take part, check the local league’s rules for quarter length, breaks and any age-specific modifications.
Reduced-player formats
When a club has fewer players, or an event is designed to be more social and accessible, teams can play with fewer than 18 on the field. Common versions include 12-a-side and 9-a-side. These games preserve the main ideas of Australian football—kicking, handballing, marking and scoring—but usually use a smaller field or adapted rules.
| Format | Typical use | What changes |
|---|---|---|
| 18 a side | Elite and many senior competitions | Full-sized team structure and usually a full oval; playing time follows the competition’s rules. |
| 12 a side | Some community, school or development games | Fewer players create more space; leagues may reduce the ground or adjust other rules. |
| 9 a side | Social, introductory or participation formats | A smaller team and often a smaller playing area; contact and other rules may be modified. |
Reduced-player football can make the game feel quicker because there are fewer bodies around the ball. It also asks players to cover more space individually, so clean disposal and communication matter. The exact rules are not universal: two competitions both called “9-a-side” may differ in field size, tackling rules and match duration.
AFL 9s and other modified games
AFL 9s is a participation-focused version designed to make the sport easier to join, including for people who may not have played full-contact football. It uses nine players per team and modified rules that restrict aspects of physical contact. Depending on the local competition, rules may specify how players can tag or stop an opponent, as well as how the ball can be advanced.
That makes AFL 9s different from simply putting nine players on each side and playing the senior game unchanged. The aim is to keep the familiar movement and skills of footy while lowering the barriers to entry. Because local organisers can use different settings, check the event rules rather than assuming every version has identical contact or timing rules.
Schools, community programs and social leagues may also make practical adjustments: a smaller ground, fewer players, shorter halves or quarters, or rules tailored to the group. These are adaptations of the game, not separate scoring systems.
Match duration, draws and finals
Match length is set by the competition, not by a single rule that applies everywhere. The AFL’s four-quarter schedule is the best-known example, but local senior leagues, junior competitions and modified events can all use different timings. In any format, time-on means the clock may be stopped for certain delays, so the scheduled quarter length is not always the time you’ll spend watching it.
A drawn match can also be handled differently depending on the competition and stage of the season. In AFL home-and-away matches, a level score at the end of regulation time can stand as a draw. Finals may use extra time to determine a winner. Other leagues and tournaments set their own procedures, so a draw does not automatically mean extra time everywhere.

Frequently Asked Questions
How many players are on an Australian football team during a match?
The standard full-field format has 18 players from each team on the field. Teams may also have interchange players, with bench numbers and rotation rules set by the competition.
How long is an Australian Rules Football match?
It depends on the competition. AFL matches use four quarters listed as 20 minutes plus time-on, while community, junior and modified games often use shorter quarters or a different schedule.
Is AFL 9s the same as a normal game with fewer players?
No. AFL 9s is a modified participation format. It uses nine players per side and can restrict contact or alter other rules, so the local competition’s regulations matter.
Do all drawn matches go to extra time?
No. The competition decides how a draw is handled. AFL home-and-away games can finish level, while finals may use extra time to produce a winner.
Final Thoughts
When people talk about Australian Rules Football’s common match formats, they usually mean the full 18-a-side game, shortened junior or community matches, and reduced-player versions such as 12-a-side or AFL 9s. They share the same basic skills and scoring, but team size, contact rules, field dimensions and playing time can change. For a particular match, the competition’s rules are the best guide to what you’ll see.
