Common Australian Rules Football Game Formats Explained

The first surprise for many newcomers is how much the match can change with the setting. A senior club game may feature 36 players on a full oval, while a social version can fit nine a side onto a smaller ground and remove tackling. The basic aim stays the same: move the oval ball forward by hand or foot and score between the posts, but player numbers, field size and contact rules depend on the format.

The standard format: 18 a side

At senior level, the familiar version of Australian rules football is played with 18 players from each team on the field. Teams can also have substitutes on the interchange bench, with the number and interchange rules set by the competition. Players rotate on and off during the match, so the 18 on the ground are not necessarily the same throughout.

Matches are played across four quarters on an oval-shaped ground. In the AFL men’s competition, each quarter has 20 minutes of playing time, with time-on added for stoppages. Other leagues and competitions can set different quarter lengths, so a community or school match may finish sooner.

Teams generally arrange players across defence, the midfield and attack, though those roles are fluid. A midfielder might push forward to create a scoring chance, while a defender can run into space to help start an attack. The ball can be kicked or handballed, and players can run with it but must bounce or touch it on the ground at regular intervals. A mark—usually a clean catch from a kick that has travelled far enough—lets the player take possession without being tackled until they play on.

The scoring system is broadly consistent across formats: a goal, kicked between the two taller central posts, is worth six points; a behind, scored between a central post and a shorter outer post, is worth one. The team with the higher score at the final siren wins.

Junior and modified football

Junior football is adjusted to suit players’ ages, experience and physical development. Depending on the league, that can mean fewer players on the field, shorter quarters, a smaller ground or modified rules around tackling and contesting the ball. Some programs also use a softer or smaller ball for younger participants.

The purpose is not simply to make a senior match shorter. A smaller-sided game gives each child more chances to run, handle the ball and make decisions. Coaches and officials can also use age-appropriate rules to keep contests suitable for the group. Exact rules differ between competitions, so parents should check the local league’s guide rather than assume every junior match follows the same setup.

AFL 9s and other social versions

AFL 9s is a popular way to play without needing a full team of 18. It is designed as a social, accessible version of the game and is generally non-contact, with tagging or touching used instead of tackling. Teams play on a smaller area, and local rules can limit how many players enter different parts of the field. That helps spread players out and keeps the game moving.

Small-sided formats are also used informally in schools, training sessions and community tournaments. A group might agree to play 12 a side, shorten the quarters or mark out a compact field. These are practical adjustments, not one universal code: the organiser should explain the rules before play, especially how contact, out-of-bounds and player rotations work.

Match length and competition structure

Player numbers are only one part of the format. Quarter length, breaks and interchange rules can differ between the AFL, women’s competitions, state leagues, local clubs and junior programs. A match in a lower grade may have shorter quarters than an elite fixture, while a tournament might use brief games to fit several matches into one day.

It is also useful to separate a game format from a competition format. Most league seasons use a home-and-away schedule, followed by finals for the teams that qualify. A one-day carnival may instead use pools or a round-robin stage before a final. Those structures affect how teams progress through a season or event; they do not necessarily change the on-field rules.

Which format should you expect?

If you are going to an AFL or senior club match, expect 18 players per team on a full oval and four quarters, with the exact timing governed by the competition. At a junior game, check the age-group rules. For a social introduction, AFL 9s or another small-sided version can be a good fit, particularly if you want a less physical game and more involvement per player.

Most matches are divided into four quarters. The length of each quarter varies by competition and age group; AFL men’s quarters are 20 minutes of playing time plus time-on.

AFL 9s is generally designed as a non-contact social format, using tags or touches rather than tackles. Check the organiser’s rules, as details can vary.

Not always. Junior competitions may adjust player numbers, field size, match length and contact rules to suit the age group. Local league rules are the best guide.

Final Thoughts

Australian rules football has a clear standard—18 a side across four quarters—but it is flexible enough to work for juniors, social players and short-format events too. Once you know the player numbers, contact rules and match length, you can quickly tell which version is being played and what to expect from the contest.
