An NRL match is controlled by one referee, two touch judges and the Bunker. That is the officiating team as the rules book itself sets it out, and it has been the arrangement in Australian rugby league since the Australian Rugby League Commission confirmed the change during the 2020 season. Before that, from 2009, the competition used two on-field referees.
The direct answer to how NRL referees work is that one official carries the whistle and the decisions, and everybody else feeds him information. The referee is the sole judge on matters of fact, with the single exception of touch and touch in-goal, which belong to the touch judges. He is also the sole timekeeper unless that job has been delegated, which in professional matches it always is. Since 2020 the touch judges and the Bunker have had licence to talk to him about the ruck, which is how the competition replaced the second set of eyes it removed.
This guide covers what each official actually does, why the NRL used two referees for eleven seasons and why it stopped, what the match officials union argued, the full signal list from the rules book, when a captain may approach the referee, how the sin bin and send-off work, and how referees are developed and appointed. The video review process that sits behind the referee is covered separately in the guide to the NRL Bunker.
Who is on the field
The rules book lists it plainly. One referee. Two touch judges. In NRL competitions, the Bunker review process on top.
The referee enforces the laws, decides matters of fact, controls the players from the moment they enter the playing area until they leave it, and may stop or terminate a match for weather, crowd interference, misbehaviour or anything else that interferes with his control of the game. He may not allow anyone other than the players onto the playing area without permission.
The touch judges each stay in touch, one on either side of the field, carry an approved flag, and rule on when and where the ball goes into touch or touch in-goal. At a kick at goal they move behind the posts and judge whether it is successful. They are at all times under the control of the referee.
The referee's whistle
The laws are specific about when the whistle is blown. It starts and ends each half. Beyond that, blowing it stops play, and the referee blows it when a try or goal has been scored, when the ball has gone out of play, when restarting play other than at a scrum, when he detects a breach of the laws, when play is irregularly affected by contact with an official or an object that should not be on the field, and when a stoppage is otherwise necessary.
The important exception is advantage. The referee does not blow for a breach where stopping play would disadvantage the non-offending team. The laws make him the sole judge of what constitutes an advantage, tactical or territorial, and note that an infringement is not cancelled simply because the ball touched an opponent. The opponent must have had a real chance to use it.
Sole judge of fact, and what that excludes
The referee judges on matters of fact and cannot later change those judgments. There is one route back: he may cancel a decision if prior foul play he did not know about is reported to him by a touch judge.
The stated exception to his authority is touch and touch in-goal. Those calls belong to the touch judges, and the laws direct the referee to accept them. On a kick at goal he looks at both touch judges before awarding it.
That structure explains a common source of confusion at grounds. A referee who appears to be ignoring a touchline dispute is not being stubborn. He has no jurisdiction over it.
The two-referee era, 2009 to 2020
The NRL introduced a second on-field referee in 2009. The reasoning was twofold: reduce the physical load on a single official across eighty minutes of increasingly fast football, and get closer control of the wrestle in the ruck.
The two worked as a lead and a pocket. The lead referee managed roughly 80 per cent of play. The pocket referee took the remaining share and concentrated almost entirely on the tackle, the play-the-ball and the defensive line. Around them sat the same two touch judges, a matchday referee coach and a senior review official in the Sydney bunker.
The workload numbers put forward by the officials at the time give a sense of the job. A match contains roughly 282 rucks, 36 kicks in play and 38 restarts, all of which have to be policed inside eighty minutes.
- Lead referee80.0%
- Pocket referee20.0%
The split reported for the two-referee model that ran from 2009 until 2020. It describes share of play managed, not share of decisions made.

May 2020: the decision and the dispute
The 2020 season began with two referees and was then suspended. When the competition planned its return, the Australian Rugby League Commission decided the game would come back with one on-field official.
The Professional Rugby League Match Officials union objected. Its central claim was a safety one: the pocket referee called around 80 per cent of ruck and play-the-ball infringements, and removing him would leave tackles, holds and throws less closely watched. The union said the decision did not take player safety seriously enough.
The dispute ran for about a fortnight and was resolved in late May 2020. The competition proceeded with one referee, with a review promised at season's end involving players, coaches, referees and management. As part of the settlement 22 full-time referees kept their employment through 2021, and part-time officials received 500 dollars a week while they were not being appointed.
What the change was meant to achieve
The competition's argument was about flow. Fewer whistles, fewer stoppages, more unstructured play. Reporting after the change noted fewer stoppages and penalties, and closer margins.
Cost was the other factor, and nobody involved pretended otherwise. Estimates of the annual saving ranged from about two million dollars to about three million, depending on who was counting and what was included. In a season where the competition had lost gate revenue entirely for a period, that was not a marginal consideration.
The change did not arrive alone. The six again rule, which restarts the tackle count for ruck infringements instead of awarding a full penalty, was introduced at the same time. The two are frequently discussed as one reform because they took effect together and both reduced stoppages.

What the touch judges took on
The officials who had worked as pocket referees did not leave the game. They moved to the touchline, which put experienced ruck officials into touch judge roles.
More importantly, the touch judges and the Bunker were given licence to communicate with the central referee about the ruck. That was the mechanism intended to replace what the pocket referee had provided. The referee still makes the call. He now receives information about the play-the-ball from officials who are not standing where he is standing.
The touch judge's traditional duties did not change. Indicating touch, judging kicks at goal, replacing a displaced corner post, reporting misconduct to the referee and staying out of the referee's control of the game are all still set out in the laws.
Reading the signals
The rules book carries a full list of referee signals and instructs the referee to indicate the nature of his decision whenever possible, point to the offending player and then signal how play restarts. It notes that repeating the signal is useful, particularly for scrum offences, because forwards with their heads down will have missed the first one.
| Decision | What the referee does |
|---|---|
| Penalty kick | Faces the non-offending team and extends an arm forward, hand slightly above shoulder level, palm at right angles to the ground |
| Differential penalty | Extends the arm as for a penalty then raises it to upright, twice, in one continuous movement |
| Scrum | Brings the tops of the fingers together with a slight downward movement, then points to the team awarded the loose head and put-in |
| Try | Points to where the try is awarded and has a touch judge stand there as a guide for the goal kicker |
| Try disallowed | Waves hands, palms down, across and in front of the body below the waist |
| Play on | Waves the hands chest high, palms facing away from the chest, across the front of the body |
| Tackle count cancelled | Raises a clenched fist above the head and waves it from side to side |
| Knock-on | Hands below the waist, palms forward, fingers to the ground, two or three forward movements |
| Forward pass | A forward movement with the straight arm indicating the line of flight of the ball |
| Field goal | Raises a hand above the head |
| Ball touched in flight | Raises one hand above the head and taps the fingertips with the other hand |
| Stealing the ball | Mimes the action of snatching the ball from the tackled player |
The play-the-ball signals are the most numerous group in the book, with more than a dozen distinct gestures covering everything from a tackled player failing to lift the ball clear of the ground to a marker retaining his hold while the ball is being played. That density is not accidental. The ruck is where most of the infringing happens.
The six again call
The six again signal tells everyone that the tackle count has gone back to zero rather than a penalty being awarded. The rules book describes the referee signalling six again and verbally indicating the restart, with the cancelled count signalled by the raised clenched fist waved side to side.
The interpretations also set out where a full penalty still applies instead. Professional fouls, repeated infringements and situations where play has broken down all produce a penalty rather than a restart. Where a full penalty is awarded for a professional foul or repeated infringements, the offending player goes to the sin bin, and teams do not have to be warned about repeated infringements first.
There is also a field position rule. A ten-metre defensive infringement produces a six again if the ball carrier plays the ball on or beyond his own 40-metre line, and a full penalty if he plays it inside that line.
The sin bin and the send-off
For misconduct the laws give the referee three escalating options: a caution, a temporary suspension of ten minutes, or dismissal.
The book is careful to add that the power to temporarily suspend is not an encouragement to deal leniently with misconduct that merits dismissal. A suspended player returns only when the referee permits it, guided by the timekeeper, and is not to be treated as a substitute. A dismissed player takes no further part and may not take up a position near the playing area where his presence is likely to provoke further incident.
A caution can be administered to a team as a whole, in which case every player is treated as having received one individually. When a final caution is given, the referee must record the offence and the time.
What happens after the match is a separate process. The Match Review Committee assesses the incident independently, as the guide to the NRL judiciary explains, and a sin bin does not guarantee a charge any more than a charge requires a sin bin.
Timekeeping and the clock
The referee is the sole timekeeper unless the duty is delegated, and in the NRL it is. A timekeeper signals half time and full time, and the referee terminates the half on receiving that signal.
The NRL interpretations then add a set of stoppage rules the international laws do not carry. Time comes off after one minute and twenty seconds from a try being awarded until the conversion is taken, after the same interval from a penalty being awarded until a kick at goal is attempted, and for at least thirty seconds after a successful kick before play restarts from halfway. In the last five minutes of the second half, time also stops after a field goal until play restarts, and after an unsuccessful kick that goes dead.
This is why the clock in an NRL broadcast behaves differently from a stadium clock at other football codes. It is being managed to a published rule, not run continuously.
Talking to the referee
Captains may only speak to the referee during a stoppage in play. The interpretations name tries, injury breaks and the issuing of a caution as the qualifying occasions, and specifically exclude penalties and scrums, which are not treated as stoppages for this purpose.
Captains also get the chance to speak as players leave the field. Where the captain is off the field, a nominated replacement may speak instead, and an additional player can be nominated to the touch judge by the head trainer during the match.
The same nomination rule applies to the captain's challenge, which is one of the reasons clubs name two players on the team sheet before kick-off as able to communicate with the referee about scrum positioning.
- 282Rucks in a match
- 38Restarts in a match
- 36Kicks in play
- 22Full-time referees retained through 2021
Workload figures put forward by match officials during the 2020 debate over the two-referee system, alongside the referee numbers set out in the May 2020 agreement. They describe a typical match rather than an exact average for any season.
How the referee uses the Bunker
The referee does not hand decisions over. He refers them. When the on-field officials require assistance for a try ruling, the interpretations direct them to consult the Bunker, and the Bunker also carries an independent responsibility for reporting foul play.
The practical consequence is that the referee's on-field call still matters. He indicates what he thinks happened before sending it upstairs, and that starting position frames the review. A captain's challenge follows the same referral signal, initiated by the captain rather than the referee.
Everything about how the review itself is conducted, what can and cannot be challenged and how long reviews take is covered in the separate guide to the NRL Bunker. The point for the referee is narrower: he decides whether to ask, and he restarts the game when the answer comes back.
Mutual infringement and the odd restarts
Some of the least understood decisions a referee makes are not penalties at all. Mutual infringement is the clearest example.
Where play is irregularly affected in the field of play, the laws direct the referee to restart by returning to the previous play. If a play-the-ball restarts the game it is not counted as an additional tackle, and the previously tackled player plays the ball. If possession had already turned over before the mutual infringement, the restart is a zero tackle to the team then in possession, at the point of the infringement but no closer than ten metres from the goal line.
The referee is the sole judge of what constitutes a mutual infringement and whether play was irregularly affected. Contact between a defender and the referee, the laws note, may not amount to one. An accidental whistle is also treated as a mutual infringement.
These are rare, they look arbitrary from the stand, and they are all written down.
The people on the sideline you do not count
The officiating team is not only the four in the middle. The laws and the interpretations reference several other roles.
A timekeeper runs the clock and signals half time and full time. An interchange official supervises replacements and works alongside a touch judge to authorise them. A match commissioner oversees the smooth running of the fixture. Head trainers, who are club staff rather than officials, have a defined role in nominating replacement players to communicate with the referee when a captain is off the field.
The referee coach is the other one worth knowing about. Under the two-referee model a matchday referee coach worked alongside the officiating team, and performance review remains part of how appointments are decided.
None of these people make decisions about play. All of them affect whether the match runs to the rules.
Origin, the grand final and the appointments that matter
Refereeing appointments in Australia work as a ranking exercise across a season, and the fixtures at the top of that ranking are the three State of Origin matches and the grand final.
An Origin match is officiated under the same laws as a club fixture but at a very different intensity, with a crowd at Suncorp Stadium or Accor Stadium whose reaction to a penalty is audible on the broadcast. Referees who handle those matches well get the grand final. Referees who do not tend to disappear from the biggest appointments for a season or two.
That is the whole career structure in one sentence: appointments follow assessments, and the assessments are continuous.
The NRLW and representative officiating
The NRLW is officiated under the same laws and the same interpretations, with the same one referee, two touch judges and Bunker arrangement.
The NRL has also worked to bring more women into the officiating pathway, and women's fixtures at both club and representative level are increasingly refereed by officials working across both competitions rather than only one. The pathway is the same one described above: district football, then a state competition, then first grade.
International matches involving the Kangaroos are refereed under the international laws rather than the NRL interpretations, which is why a fixture in the Pacific Championships or a World Cup can look subtly different in the ruck. The interpretations that produce the six again call are an Australian competition rule, not a law of the game.
Where referees stand and how they move
A referee under the single-referee model works predominantly behind the defensive line at the play-the-ball, moving to a position where he can see both the ruck and the ten-metre line, then tracking play as it develops.
The laws require him to be well sighted, and the practical effect is a great deal of running. The pocket referee's removal did not reduce the number of rucks, kicks or restarts in a match. It concentrated them on one official, which is why the physical demands of the job and the way referees are rotated across a round became a live issue after 2020.
Touch judges cover the touchline for the length of the field, and the laws note that a touch judge should not necessarily remain stationary when the ball is kicked at goal.
Positioning also decides what a referee can see. Standing square behind the ruck gives him the play-the-ball and the marker but a poor view of the far side of the defensive line. Standing wider gives him the line but a worse angle on the tackle. Every position is a trade, and the choice he makes at each play-the-ball determines which infringements he is capable of detecting at all. That is the part of the single-referee argument that never really went away, because no amount of communication from the touchline changes where the man with the whistle is standing.
Becoming an NRL referee
Australian referees come up through the same pyramid as players. Junior and club football in a local district, then representative fixtures, then a state competition such as the NSW Cup or the Queensland Cup, then first grade.
Officials are assessed continuously. Performance across a season determines appointments, and the biggest fixtures go to the officials rated highest. That includes State of Origin and the grand final, which is the appointment every referee in the country is working towards.
The pool contains both full-time and part-time officials. The May 2020 agreement fixed the full-time number at 22 through 2021, and numbers have been reviewed between seasons since.
Refereeing below the NRL
The gap between first grade and everything below it is wide. A NSW Cup or Queensland Cup fixture has a referee and two touch judges but no Bunker, so try decisions are made in real time by officials on the field.
Below that, in country and junior football, the officiating team gets smaller again. A district game may have a referee and volunteer touch judges. In-goal judges, which the laws provide for where there is no video referee, are used in some competitions.
That is worth remembering when a decision at Allianz Stadium or AAMI Park is compared to one from a suburban ground. The same laws apply. The apparatus available to apply them does not.
The criticism, and what it is usually about
Referees in Australian rugby league take a level of public criticism unusual even by professional sport's standards. Most of it lands on two things: consistency between matches, and the volume of stoppages.
Some of that is genuinely about officiating. A good deal of it is about the rules themselves. A referee applying an interpretation exactly as written will still produce an outcome supporters dislike if they dislike the interpretation. Six again calls, obstruction rulings and the professional foul sin bin are the recurring examples.
The single-referee model added a third strand. With one official rather than two, a missed ruck infringement has a single obvious address, and the union's 2020 warning gets quoted every time one occurs.
Watching a match as an officiating exercise
If you want to follow the officiating rather than the football, watch the touch judges rather than the referee. They move constantly, they signal touch and touch in-goal, and since 2020 they are talking to the referee about a ruck he is looking at from a different angle.
Then watch the referee's hands. Almost every decision has a prescribed signal, and the book instructs him to indicate the nature of the offence before signalling how play restarts. Once you can read the knock-on signal, the forward pass signal and the cancelled tackle count, the flow of a match becomes far easier to follow from a seat high in the stand.
Grounds such as Suncorp Stadium and Accor Stadium put a big screen replay up for Bunker referrals, but the on-field signals are the only running commentary you get on everything else.
What to check each season
Officiating arrangements are among the most frequently amended parts of Australian rugby league, so a few things are worth verifying rather than assuming.
The number of on-field referees has changed twice in the past two decades and could change again. The rules book is the place to confirm the current position, and the NRL interpretations section is where competition-specific arrangements live.
Referee numbers, both full-time and part-time, are reviewed between seasons. So are the stoppage and timekeeping rules, which have been adjusted several times as the competition has chased a faster game.
And the interpretations that generate most of the argument, particularly around the ruck and the six again call, are reissued each pre-season. For the wider Australian picture, start at the Australia hub, the rugby section or the sports index.
