Tackling in the AFL: Technique, Rules and the Duty of Care

There is no other contact sport where a player is required to hold an object with both hands, is legally allowed to be seized around the body by an opponent running at full speed, and is then punished for failing to get rid of it quickly enough. The tackle in Australian football sits at that intersection, and it has become the most legally scrutinised act in the game.

The AFL tackling rules are, at their base, simple. A player in possession of the football may be tackled between the shoulders and the knees. Contact above the shoulders or in the back is a free kick against the tackler. If the tackle is legal and the player with the ball fails to dispose of it properly, the free kick goes the other way. Everything complicated sits on top of that base, in the space where a legal tackle becomes an unreasonable one, and that space has been narrowing every year since concussion litigation reached the Supreme Court of Victoria.

This page covers the technique of a tackle in the order it is coached, the point at which the law turns against the tackler, what the AFL actually weighs when judging a dangerous tackle, the sling and the spear, what the 2026 changes did, and the duty of care argument that explains why the interpretation keeps tightening. For the disposal that a tackled player has to produce, see the handball.

What a legal tackle is

A tackle in Australian football is the act of using the hands and body to seize, hold or bring to ground an opponent who is in possession of the football.

Three conditions have to hold. The opponent must actually have the ball. The contact must be between the shoulders and the knees. And the tackler must release the player once they have legally disposed of the football.

If the opponent does not have the ball, holding them is holding the man. If the contact is above the shoulders, it is a high tackle. If it is in the back and the tackler pushes rather than wraps, it is in the back. Each of those is a free kick against the tackler regardless of how good the intention was, because Australian football has never asked whether the tackler meant it when the contact itself is prohibited.

The legal target area, and why it is drawn where it is

Below the shoulders is a head protection line. Above the knees is a leg protection line. Between them is the torso, which is the only part of a human being that can absorb a running collision without a joint or a brain taking it.

The line is drawn at the shoulders rather than at the neck because a tackle that lands on the shoulder can slide upwards, and the Laws would rather penalise a marginal shoulder contact than adjudicate every ride-up. This produces the most complained-about free kick in the code: the tackler who wraps at chest height on a player who then drops their body, and finds their arms have arrived at the neck.

Umpires are instructed to judge where the contact ended up rather than where it started, which is why the tackled player's own movement can create a free kick against a tackler who did nothing wrong. The 2026 shrug change was designed to take one deliberate version of that manipulation out of the game.

Technique: the approach and the last two steps

Coaching a tackle in Australia starts before the contact. The approach line decides everything.

The recommended line is from the side or slightly behind rather than square on, because a square approach means both players' momentum meets head-on and neither can control the fall. Approaching at an angle lets the tackler use the opponent's own direction of travel.

The last two steps are where technique is either present or absent. The tackler should shorten their stride, drop their centre of gravity and get their feet close enough to the opponent that the arms do not have to reach. A tackle made at full stride with extended arms is the one that becomes a sling, because the tackler has no base and the only thing available to bring the opponent down is rotation.

Where the arms go

Both arms wrap. This is the single most important instruction in safe tackling and it is also the one most often broken under fatigue.

A one-armed tackle produces rotation almost automatically, because the force is applied to one side of the opponent's body and they spin around the point of contact. A two-armed wrap distributes force across the torso and keeps the opponent's body square to the ground.

The height matters as much as the number of arms. Coaches teach the arms to arrive at the ribs, below the ball but above the hips, because that is the point where the tackler can both restrict the opponent's arms and control the descent. Arms that arrive higher pin the shoulders and risk the neck. Arms that arrive lower turn the tackle into a leg drag, which drops the opponent face first.

Bringing a player to ground

The Laws permit bringing an opponent to ground. What they do not permit is doing so in a way that is unreasonable in the circumstances.

The safe method is to use the legs to lower the opponent rather than the arms to throw them. The tackler bends, takes the weight, and goes down with the opponent, staying underneath or alongside rather than driving on top. This is slower than a sling and it is why players under pressure default to the dangerous version.

The instruction that most Australian junior coaches now emphasise is the one that costs nothing: once the opponent is falling, stop adding force. Almost every tackle that ends in a suspension involves the tackler continuing to apply force after the outcome was already decided.

1. 1The tackleA tackle is laid and the umpire either pays a free kick, plays on, or reports the incident.
2. 2ReviewThe Match Review Officer reviews the incident along with every other reportable act from the round, using vision from all available angles.
3. 3ClassificationThe incident is classified as either a classifiable offence that can be graded, or one serious enough to be sent directly to the tribunal.
4. 4GradingA classifiable offence is graded on conduct, on impact and on the area of contact, which together determine the sanction.
5. 5OfferThe player is offered a set penalty, which they can accept, or reduce with an early guilty plea where that option applies.
6. 6TribunalIf the player contests the charge, or if the offence was sent directly, the AFL Tribunal hears the matter and decides.
7. 7AppealA decision can be appealed on limited grounds to the Appeals Board, which does not simply rehear the case.

A structural description of the AFL disciplinary sequence as published, not a timeline of any specific case. Most tackles never leave the first step, and the great majority of those that are assessed result in no charge.

When a legal tackle becomes rough conduct

Rough conduct is defined as any conduct against an opposition player which in the circumstances is unreasonable. That is a deliberately open standard, and it is the hook on which every dangerous tackle charge hangs.

Because it is open, the AFL publishes guidance about what is weighed. In determining whether a tackle is a reportable offence, and whether the conduct was careless or intentional, four considerations are named.

Whether the tackle consists of more than one action. Whether the tackle is inherently dangerous, with the example given being a spear tackle where a player is lifted from the ground and their head is driven into the ground. Whether the tackled player was in a vulnerable position without great opportunity to protect themselves, with the example given being arms pinned to the body so they cannot safely brace for contact with the ground. And whether the tackler has slung, driven or rotated their opponent into the ground with excessive force.

Those four are the entire architecture of the modern dangerous tackle. Almost every suspension handed down for a tackle can be traced to one or more of them.

More than one action

The first consideration is the most practically useful for a spectator trying to judge a tackle in real time.

A tackle that is a single continuous movement, where the tackler grabs and both players go to ground together, is very rarely reportable. A tackle with a second movement, where the tackler completes the tackle and then adds force, is where the trouble starts.

The second action is usually visible without slow motion. Watch for the tackler's hips: if they rotate after the opponent has already been secured, force is being added rather than absorbed. That is the moment a tackle stops being a tackle and starts being a throw.

The sling tackle

The sling tackle is the version the AFL has spent the most effort trying to remove. It is a tackle in which the tackler whips the opponent into the ground, usually by rotating their own torso while holding the opponent's upper body.

It is efficient, which is the problem. A sling puts the opponent on the ground faster than any other method and it very often forces a turnover. The player being slung has no control over their landing, and if their arms are pinned they cannot break the fall.

It is also the tackle most likely to produce a head impact, because the rotation drives the opponent's shoulders down and the head follows. There have been repeated public calls in Australia for automatic bans where a sling tackle knocks an opponent out, and the AFL's response has instead been to tighten grading and umpire interpretation rather than to introduce a mandatory sanction.

The spear tackle and lifting

The spear tackle, where a player is lifted from the ground and their head is driven into the turf, is the example the AFL uses for a tackle that is inherently dangerous.

Inherently dangerous is a meaningful category. It means the act does not require any additional aggravating factor to be reportable. A tackle that lifts and drives is reportable on its face, regardless of whether the opponent was injured and regardless of what the tackler intended.

It occurs far less often in Australian football than in the rugby codes, mostly because the ball carrier is usually running rather than standing still and because there is no legal contest for a ball carried into contact. When it does happen it draws the heaviest sanctions available.

Rotational force and the vulnerable player

The two remaining considerations tend to arrive together. A tackled player whose arms are pinned is vulnerable, and rotation applied to a vulnerable player is what produces the worst outcomes.

Pinned arms remove the reflex that protects the head. Every person falling puts their hands out. Take that away and the head takes the impact directly. This is why the AFL specifically names the pinned arm as a vulnerability factor rather than leaving it to general judgement.

Rotation is worse than a straight drop because it adds angular velocity to the head. A player driven straight into the ground lands with the force of the fall. A player rotated into the ground lands with the force of the fall plus whatever the tackler's torso added, and the head arrives first because it is furthest from the axis of rotation.

The 2023 directive: the head hits the ground

During the 2023 season AFL umpires were directed to treat tackles that cause an opponent's head to hit the ground as dangerous. This was a change of interpretation rather than a change of law, and it was significant precisely for that reason.

It shifted the assessment towards outcome. Previously the question was primarily about what the tackler did. After the directive, the fact of head-to-ground contact put the tackle into the dangerous category and required a justification for why it should not be penalised.

Players and their association publicly sought clarification, arguing that the tackler cannot always control where the opponent's head goes, particularly when the tackled player ducks or drops. That tension has never been fully resolved and it is the live argument in Australian football every Monday.

• 190Tackles by Matt Rowell in the 2023 home-and-away season
• 19Single-game tackle record
• 3Players sharing that single-game record

AFL statistical records for tackles begin in 1999, so these figures do not cover the earlier history of the VFL and AFL. The single-game record of 19 is shared by three players, set in separate matches.

The tacklers, and what the numbers mean

Matt Priddis holds the career record with 1,587 tackles across an 11-year career from 2006 to 2017, which is an extraordinary figure for a player who was overlooked in his draft year and won a Brownlow Medal doing exactly this.

Matt Rowell holds the home-and-away season record with 190 in 2023, an average of 8.3 a match, and Gold Coast built a midfield identity around it. Hugh Greenwood's 8.67 tackles a game in 2021 remains the highest season average, narrowly ahead of Priddis on 8.55 in 2016.

The single-game record of 19 is shared by Tom Liberatore, Jude Bolton and Jack Ziebell. What all these numbers really measure is not aggression but positioning: the players at the top of tackle lists are the ones who consistently arrive at the contest a fraction after the ball, which is exactly the wrong place to win a possession and exactly the right place to lay a tackle.

What the Match Review Officer weighs

Once a tackle is reported, the assessment moves off the field. The Match Review Officer looks at every reportable incident from the round and either classifies the offence so it can be graded, or refers it directly to the tribunal if it is serious enough.

For a classifiable offence the grading turns on three axes: the conduct, meaning whether the act was careless or intentional, the impact of the act, and the area of contact on the opponent's body. Those three combine into a sanction, which the player can accept or contest.

The 2026 framework gave the MRO greater flexibility when grading careless acts that cause concussion, and added the ability to charge players for rough conduct where they forcefully push an opponent into a dangerous situation. The second of those extends the reach of rough conduct beyond the tackle itself, to acts that put an opponent into danger without ever gripping them.

The 2026 changes and the tackle

Several of the 2026 law changes reshape the environment in which tackles are laid, even though only one of them is about tackling directly.

The centre bounce has been abolished, with quarters and goals restarting from a centre ball-up where the umpire throws the ball up. The medical substitute has gone: clubs name 23 players with five on the interchange bench, all available to come on at any time, and the 75-rotation cap is retained. Last disposal out of bounds between the arcs is now a free kick regardless of intent. Finals have moved to a final ten with a wildcard round.

The change that matters most for tacklers is the shrug. From 2026 a shrug inside a tackle counts as prior opportunity, which means the tackled player must dispose of the football immediately or concede a free kick. Part of the stated reasoning is that shrugging drags a tackler's arms upwards towards the head and manufactures high contact free kicks against a tackler who has done nothing wrong. Removing the incentive removes the free kick.

Duty of care and the concussion class action

Behind all of this sits litigation. Proceedings led by former Geelong player Max Rooke have been lodged in the Supreme Court of Victoria against the AFL and multiple clubs, with further former players joining as plaintiffs. The claim alleges players suffered permanent, life-altering injuries from concussions sustained during their careers, and that the league and clubs were negligent in their duty of care.

Australian sports law analysis of the AFL's tackling crackdown makes the connection explicit. The argument is that as long as the AFL has made a concerted effort to reduce the likelihood of head-related injuries, it is likely to have discharged the prospective duty of care it owes to players. Tightening the interpretation of dangerous tackles on the field, and tightening the grading of rough conduct at the tribunal, is precisely that kind of effort.

This is why the tackling interpretation has moved in one direction for a decade and shows no sign of moving back. The AFL is not only refereeing a game. It is managing an exposure, under Australian workplace health and safety obligations as well as at common law, and each season's changes are also evidence of effort.

The player's side of the argument

The players' position has never been that head injuries do not matter. It has been that the tackler is being asked to control an outcome that is partly determined by somebody else's body.

The specific complaints are consistent. A tackled player who ducks into contact creates high contact from a legal start. A tackled player who drops their knees drives their own head towards the ground. A tackled player who shrugs pulls the tackler's arms upwards. In each case the tackler is penalised for a position they did not create.

The AFL has responded to one of those three directly with the 2026 shrug change. The other two remain matters of umpire judgement, which is why players continue to seek clarification and why the same tackle produces two confident and opposite opinions in every crowd at the MCG and Marvel Stadium.

Tackle numbers and why the game got so dense

Tackle counts across the AFL rose steadily through the 2000s and 2010s for reasons that had nothing to do with the tackling law. Zone defence, higher interchange rotations, more players behind the ball and a coaching preference for pressure over possession all pushed the ball into congestion.

More congestion means more tackles, and more tackles laid at speed in a confined space means more chances for one of them to go wrong. The safety problem in Australian football is therefore partly a tactical problem, and the AFL's rule changes over several seasons have consistently tried to open the ground up as well as to police the tackle.

That is the underlying logic of changes like the last disposal out of bounds free kick: fewer stoppages, less congestion, fewer tackles laid in packs. The tackling law and the ball movement law are working on the same problem from different ends.

Community football, juniors and the same law

The Laws of Australian Football apply across the code, so a Saturday afternoon tackle in a country league in Victoria or a suburban competition in Perth is judged against the same definition of rough conduct as one at Optus Stadium.

What differs is the machinery. Community leagues run their own tribunals with their own penalty schedules, and the AFL's Match Review Officer framework does not apply below the elite competitions. Junior football in Australia layers additional restrictions on top, with modified or no-tackle formats for the youngest age groups and progressive introduction of contact as players move up.

Concussion protocols have followed the same path. Return-to-play timelines and mandatory stand-down periods now apply at community level across Australia, and the practical effect is that a suburban club has obligations that would have seemed extraordinary a decade ago. The training and assessment of the officials who apply all this is a separate problem again, and the parallel with cricket umpiring in Australia is close: the law is national and the person applying it on a Saturday is a volunteer.

Coaching a tackle that is both safe and effective

The useful thing about the current law is that the safest tackle is also the most effective one. A two-armed wrap at the ribs, made from a low base with the feet underneath, pins the opponent's arms against the ball rather than against their body, prevents a disposal, and puts them on the ground under control.

The dangerous versions are all shortcuts taken by a player who arrived badly. The sling is what a tackler does when their feet are too far away. The one-armed drag is what happens when they arrive late. The drive-through is what happens when they are running too fast to stop.

The coaching implication is that tackling technique is mostly footwork. Australian junior programs increasingly teach it that way, working on the approach angle and the final two steps before any contact is made at all.

Tackling in the AFLW

The AFLW plays under the same Laws, and the same rough conduct definition and dangerous tackle considerations apply. The tribunal machinery is comparable, and dangerous tackle charges have been contested there in the same way they are in the men's competition.

Where the competitions differ is in the shape of the contest rather than the law. AFLW matches are played with shorter quarters and a different congestion profile, and the tackle counts reflect that. The interpretation, however, has moved in the same direction and at the same time, because the duty of care argument does not distinguish between competitions.

The practical consequence is that anyone learning to judge a tackle can use exactly the same four questions in either competition, which is not true of every rule in Australian football. Interpretations of holding the ball, by contrast, have at times been applied differently between the two.

What to watch for at a match

When a tackle looks contentious, ask the four questions the AFL itself asks, in order. Was there more than one action. Was the tackle inherently dangerous. Was the tackled player vulnerable, particularly with pinned arms. Was there a sling, a drive or a rotation with excessive force.

If the answer to all four is no, the tackle is almost certainly fine no matter how heavy it looked. If the answer to any is yes, the tackle is in the review system regardless of whether anyone was hurt.

The rest of the code sits around this one act. For the disposal a tackled player has to produce, see the handball. For the venues, competitions and rules that frame it, the Australian sport hub and the sports index are the starting points, and grounds like Adelaide Oval and the Gabba show how differently the same tackling law plays out on surfaces of different sizes.
