Rugby Union vs AFL Key Differences
In Melbourne, Australian rules football is far more than a sport. It is part of the city’s identity, with packed stadiums, weekend rituals, and a famous Grand Final every September. Rugby union, meanwhile, has a smaller but passionate following in the city, from local Dewar Shield clubs to huge crowds for Wallabies Tests at the MCG.
Both games use an oval ball and involve tough physical contact, but that is where the similarities largely end. This guide explains the key differences between rugby union and AFL, from the field and team size to scoring, passing, tackling, and the culture around each code.
Quick Comparison

| Match length | Two halves of 40 minutes | Four quarters, plus added time |
| Main score | Try, worth 5 points | Goal, worth 6 points |
| Passing by hand | Thrown, backwards or sideways only | Handball, punched off one hand, any direction |
| Forward passing | Only by kicking | Kicking and handball allowed in any direction |
| Offside | Yes | No general offside rule |
| Global reach | Played worldwide, with a World Cup | Mainly played in Australia |
Origins of Each Game
Rugby union developed in England in the 19th century and spread across the British Empire and beyond. Today it is played in more than 100 countries, with the Rugby World Cup as its pinnacle.
Australian rules football was born in Melbourne in the late 1850s, when early rules were drawn up for the Melbourne Football Club. The game grew rapidly in Victoria and later spread across Australia. The modern Australian Football League, or AFL, is the sport’s top professional competition.
The Playing Field
Rugby union is played on a rectangular field with H-shaped posts at each end. Behind the try line is the in-goal area, where tries are scored.
AFL is played on a large oval field, often a cricket ground, such as the famous MCG. At each end are four upright posts: two taller goal posts in the middle and two shorter behind posts on either side. The AFL field is much larger than a rugby field, which is why AFL players often run long distances during a match.
Team Size
Rugby union has 15 players per team on the field, split into forwards and backs, with replacements on the bench. AFL has 18 players per team on the field, plus a small interchange bench. AFL players rotate on and off frequently during a match, while rugby replacements usually come on once and stay on.
Scoring Differences
| Rugby Union Score | Points | AFL Score | Points |
|---|---|---|---|
| Try | 5 | Goal (between the two tall posts) | 6 |
| Conversion | 2 | Behind (between a goal post and behind post, or touched) | 1 |
| Penalty or drop goal | 3 | No equivalent | – |
In rugby, the main way to score is by grounding the ball for a try. In AFL, every score comes from kicking or the ball passing between the posts. AFL scores are often written as goals, behinds, and total points, for example 12.10 (82).
Moving the Ball
Rugby Union
In rugby, the ball must be passed backwards or sideways. Players gain ground by running, kicking, or driving in scrums and mauls. Losing the ball forward results in a knock-on.
AFL
In AFL, players move the ball by kicking or handballing, which means holding the ball in one hand and punching it with the other. Throwing the ball is not allowed. Both kicks and handballs can go in any direction. Players running with the ball must also bounce or touch it on the ground regularly.
The Mark
A key feature of AFL is the mark. When a player cleanly catches a kick that has travelled far enough, they earn a free kick, often leading to spectacular high marks over packs of players. Rugby has a similar idea, where a player catching a kick in their own 22-metre area can call a mark, but it is far less central to the game.
Tackling and Contact
Both sports involve heavy contact, but the rules differ:
- Rugby union: players tackle the ball carrier below the shoulders, and the tackled player must release the ball, leading to a ruck
- AFL: players tackle between the shoulders and knees, and a player caught holding the ball without disposing of it properly can be penalised
Rugby has structured contests such as scrums, lineouts, and mauls. AFL has no scrums or lineouts; instead, play restarts with ball-ups, throw-ins by boundary umpires, and centre bounces after goals.
Positions and Structure
Rugby positions are numbered from 1 to 15, with clear roles for forwards and backs. AFL teams are arranged across the ground in forward, midfield, and defensive lines, with key roles such as ruckmen, midfielders, key forwards, and key defenders. Without an offside rule, AFL players can move freely across the entire field.
Officials
Rugby union uses one main referee, two assistant referees, and a Television Match Official in professional matches. AFL uses a team of field umpires, boundary umpires, and goal umpires, along with video review for scoring decisions.
Culture and Popularity
AFL dominates the sporting landscape in Victoria, South Australia, Western Australia, and Tasmania, with huge crowds every week during the season. Rugby union’s Australian heartlands are New South Wales and Queensland, but it has a dedicated community in Melbourne, supported by Dewar Shield clubs and big events such as the Bledisloe Cup at the MCG.
Internationally, rugby union has the bigger footprint, while AFL remains a uniquely Australian game with a growing number of international players.
Seasons and Match Days
The two codes also share a winter calendar, which explains why they often compete for grounds and attention in Melbourne. The AFL season runs from autumn through to the Grand Final in late September. Victorian club rugby is also played through autumn and winter, with Dewar Shield finals in August, while international rugby Tests are mainly played in July, August, and November.
The match-day experience feels different too. AFL games at the MCG or Docklands often attract crowds of 50,000 or more for big fixtures, with fans in club colours and long-standing rivalries between Melbourne suburbs. Rugby club days are smaller and more relaxed, often with several grades playing on the same afternoon, while major rugby Tests bring a festival atmosphere and international supporters to the city.
Can You Enjoy Both?
Absolutely. Many Melbourne sports fans follow both codes. AFL offers fast, free-flowing action across a huge field, while rugby union delivers set-piece battles, tactical kicking, and international rivalries. Some athletes have even switched between the codes during their careers, using skills such as catching, kicking, and tackling in both.
Final Thoughts
Rugby union vs AFL key differences include the field shape, team size, scoring system, and how the ball is moved. Rugby is about tries, backward passes, and structured contests, while AFL is about goals, kicking, handballs, and marks on a giant oval. Both are physical, exciting, and deeply loved, and in Melbourne, fans have the chance to enjoy the best of both worlds.
