The six again rule is the law that lets an NRL referee restart a team's tackle count without stopping play. When a defender infringes in the ruck, the referee rotates one arm above his head, calls "six again", and the attacking side simply carries on with a fresh set of six tackles. No whistle, no tap restart, no shot at goal, no pause. The defence gets nothing back — not a breather, not a chance to reset the line, not the twenty-odd seconds a penalty used to buy.
It arrived on 28 May 2020, when the NRL resumed after being shut down by COVID-19 in March, and it changed the look of Australian rugby league faster than any law change since the six-tackle rule itself. Within a season, points per game were up, penalties per game were down by a third, and coaches were rebuilding their defensive systems around the assumption that the ruck could no longer be slowed for free.
What followed was six years of adjustment. The rule was widened in 2021 to cover offside infringements, wound back in 2022 for infringements near a team's own line, and adjusted again for 2026 when the zone in which a penalty still applies shrank from the forty-metre line to the twenty. This page traces all of it: the mechanism, the reasoning, the numbers, the fatigue argument, and what is actually settled versus what is still contested. The wider laws are covered in the NRL rules for beginners guide, and the mechanic the rule protects is set out on the play the ball page.
What a set restart actually is
Rugby league gives a team six tackles with the ball. On the sixth, possession changes hands where the tackle is made. A set restart returns that count to zero.
That is all it does. It gives no territory, no points, no possession that the side did not already have. Its entire value is time and tackles: six more chances to attack from where you already are, against a defensive line that has not been allowed to stop and reorganise.
Compare that with a penalty, which does four things at once — it stops the clock in practical terms, it lets the attacking side kick for touch and keep the ball, it offers a shot at two points, and it forces the defence back ten metres while giving it time to get there in order. The six again removes three of those four. The attacking side gains only the fresh count.
The NRL's official language is "set restart". Everybody, including the referees, says "six again".
Spotting it live
There is no whistle, which is why first-time viewers miss it. Blowing the whistle would stop play, and stopping play is the thing the law exists to avoid.
Instead the referee raises one arm straight up and rotates it in a circle, calling six again as he does. On broadcast the graphic showing the tackle count resets, which is often the first clue a casual viewer gets. At a ground you have to be watching the referee, who is usually positioned about ten metres behind the play the ball and to one side.
The signal is deliberately large and visual so that the dummy half can register it without breaking stride. A side that sees the restart early will often speed up rather than slow down, because the defence in front of it is the one that has just been penalised and is therefore the one out of position.
The problem the NRL set out to solve
By the late 2010s the ruck had become a wrestle. Defensive systems were built on slowing the play the ball: extra defenders arriving late into the tackle, a third man to control the ball carrier's hips, a slow release, a hand on the ball, a marker standing square a fraction longer than he should. All of it cost fractions of a second, and all of it added up.
The penalty was supposed to deter that, but it had a perverse effect. A penalty stopped the game. For a defence that was scrambling, gasping and out of shape, a penalty was very often a better outcome than the alternative. The side conceded a tap or two points, but it also got a rest and a chance to get thirteen players back into a straight line. Coaches understood this arithmetic perfectly well.
NRL analysis before the change put the average penalty stoppage at about twenty-two seconds, and estimated that removing ruck penalties would add just under two minutes of ball-in-play time per match. The two minutes was the headline. The twenty-two seconds was the real target.
May 2020: shutdown, one referee, new law
The 2020 season was suspended on 23 March after two rounds, the first time in the competition's history that had happened. The NRL announced on 9 April that it intended to restart on 28 May, and in the weeks between it pushed through a set of changes that would ordinarily have taken a full off-season of consultation.
Two of those changes are permanently linked in people's memory. The competition went back to one on-field referee, having used two since 2009 — a move the referees initially threatened to strike over before an agreement was reached on 22 May. And ruck infringements stopped producing penalties and started producing set restarts.
The context matters. A competition restarting mid-pandemic under biosecurity restrictions, with crowds absent and a compressed twenty-round season, was in an unusually good position to change something radical, because everything was already unfamiliar. A rule that might have taken three years of committee work went in over six weeks.
Which offences produce a restart
The six again covers the family of defensive offences at the ruck that used to bring a penalty:
- Holding down. The tackler does not release the ball carrier promptly enough for him to get up and play the ball.
- Lying on the tackled player. The most common version, and the hardest for a viewer to see from the stands.
- Hand on the ball. A defender interfering with the ball in the ruck.
- Leg pull. Dragging the tackled player's leg to unbalance the play the ball.
- Crowding the play the ball. Markers or defenders standing too close.
- Marker not square. A marker who is not properly in front of the man playing the ball.
From 2021 the list also included the ten-metre offside infringement, where a defensive line fails to retreat the full ten metres before advancing.
Which offences still bring the whistle
The set restart never replaced the penalty entirely, and understanding what it does not cover is the key to understanding the whole law.
A full penalty still applies for a professional foul, for repeated team infringements after a warning, for offside interference with a kick or a play, for dangerous contact and foul play of any kind, and for offences committed inside the zone near a defending side's own line.
That last category is the one that keeps moving. Referees can also escalate: a player judged to be infringing cynically to buy time can be sent to the sin bin for ten minutes, and from the rule's first weeks the NRL made clear that a professional foul in the ruck carried automatic sin-bin risk. The set restart was designed to be a lighter sanction applied more often, not a licence.
2021: the rule grows a second head
For the 2021 season the NRL extended set restarts to ten-metre offside infringements. The reasoning was identical to 2020: a defensive line that had not retreated its ten metres was buying an advantage, and a penalty rewarded it with a stoppage.
The effect showed up immediately in the data. NRL analysis of the opening rounds found ruck set restarts had fallen to about 5.3 per game, down from around seven the previous year, with the new ten-metre restarts running at about 1.8 per game. Penalties per game across the opening two rounds averaged about 6.7, against roughly 10 in 2020.
Three other 2021 changes landed in the same package and are routinely confused with six again:
- The two-point field goal for kicks struck from beyond the forty-metre line.
- The goal-line drop-out replacing the twenty-metre restart when an attacking kick is grounded in-goal by a defender, when the ball is held up over the line, and when an attacker knocks on in-goal.
- The play-the-ball restart replacing the scrum when the ball goes into touch in most situations.
The goal-line drop-out change is the one that most plausibly drove the 2021 scoring spike, because it repeatedly handed attacking teams possession forty or fifty metres closer to the line than the old law did. Six again gets the credit and the blame for a season it only partly caused.
2022: the forty-metre wind-back
By the end of 2021 the criticism had a specific shape. Sides were conceding set restarts deliberately in their own end, absorbing the fresh count as the price of getting their defence set, and the law that was supposed to punish cynicism was being used to fund it.
The NRL's answer for 2022 was zonal. Infringements committed inside a team's own forty-metre zone went back to being full penalties. Everything outside that remained a set restart. The stated reasoning was that this provided additional deterrence to defending sides willing to concede restarts for a tactical advantage.
The effect was blunt. Set restarts per game fell from about 7.1 in 2021 to about 3.8 in 2022 — close to half. Tries per game came back from 8.1 to 7.6, and points per game from roughly 46.2 to 43.3. Ball-in-play barely moved, sitting around 54 minutes in both seasons.
Whether that was a correction or an over-correction has been argued ever since. It certainly restored the tactical logic the rule was meant to remove: inside your own forty, giving away a penalty near your line once again bought you a stoppage.
2026: the zone shrinks to twenty metres
The Australian Rugby League Commission confirmed four on-field changes for the 2026 season in early February that year. One of them addressed the zone directly: infringements beyond the twenty-metre line now produce a set restart, replacing the forty-metre threshold that had applied since 2022.
In practice that hands twenty metres of field back to the attacking side. A defensive infringement thirty metres from a team's own line, which from 2022 to 2025 bought a stoppage, now buys a fresh set of six against a defence that has not been allowed to reset.
The same 2026 package restricted trainers to defined circumstances for entering the field, which removes another route to slowing the ruck; changed the interchange to four players from a bench of six across eight swaps from a nineteen-man squad; and removed the seven-tackle set following an attacking knock-on in-goal. A proposed kick-off change, letting the conceding side choose to kick or receive, was not adopted and will be trialled in end-of-season matches with no bearing on the finals.
| Season | What applied | Set restarts per match |
|---|---|---|
| 2019 | Ruck infringements penalised. No set restart exists | None |
| 2020 | Set restart introduced from the 28 May resumption for ruck infringements | Around 7 for rucks |
| 2021 | Extended to ten-metre offside infringements | About 7.1 |
| 2022 | Infringements inside a team's own forty-metre zone return to penalties | About 3.8 |
| 2026 | Penalty zone moves in to the twenty-metre line | Not yet settled |
The fatigue argument
The intended mechanism was fatigue. Remove the stoppages, and a defending side that has been under pressure for three sets cannot buy relief. The reward flows to the fitter team and to the team with the ball.
That worked, but not in the direction most people assumed. The obvious prediction was that removing penalties would lengthen matches in play. Ball-in-play figures suggest it did so only briefly: roughly 55.9 minutes in 2020, then 54.13 in 2021 and 54.05 in 2022. The 2020 season was the peak.
What changed more was the shape of the time rather than the total. In 2020 there were about 295 play the balls per game, roughly twenty more per game than in 2019, as coaches used the restarts to run their attacking structures again from tackle one. That number came back to about 282 by 2022. More play the balls at similar total ball-in-play means shorter gaps, more repeat efforts and less recovery inside each passage of play — which is exactly what fatigue means to a middle forward.
The injury question sits on top of that and is genuinely unresolved. The concern that more continuous play produces more fatigued tackling, and that fatigued tackling is worse tackling, is coherent and was raised from the first weeks. It has not been cleanly demonstrated, and the interchange cap moves in the opposite direction. Anybody making a confident claim in either direction is going further than the published evidence supports.

How coaches adapted
The first response was conditioning. If the ruck could not be slowed for free, the defensive middle had to be able to make repeat efforts without recovery, and preseason programmes shifted accordingly. Bench management got sharper, because with eight interchanges and no penalty stoppages a coach's substitution windows became a genuine tactical resource rather than a routine.
The second response was structural. Defences moved away from wrestling to slow the ruck and towards line speed — getting off the line hard and making the tackle further from the previous play the ball, so that the attacking side's fresh set started deeper. If you cannot buy time after contact, you buy space before it.
The third was in attack. The value of a hooker who could run from dummy half rose sharply, because the moment immediately after a restart is when a defensive line is most likely to be short a man or standing in the wrong place. Sides began to script the first two tackles after a restart rather than treating them as a reset.
The wrestle did not disappear
One prediction that did not come true is that the six again would end the wrestle. It did not. What it did was change where the wrestle happens and how much it can cost.
Defenders still work to control the ball carrier's body position in the tackle, still aim to get the third man in, still try to land in a way that delays the play the ball by a fraction. The difference is that the fraction has to be small enough to survive a referee watching for exactly that behaviour, in a competition where the sanction is now cheap enough to be given ten times a match.
Inside a team's own zone, where the penalty still applies, the older calculus survives in reduced form. That is precisely why the 2026 change moved the boundary in.
Cynical infringing and the sin bin
The law depends on an escalation ladder, and the ladder is what stops the restart being a licence.
The first rung is the restart itself. The second is a warning to the captain that his side is infringing repeatedly. The third is a full penalty for a professional foul or for repeated team infringements. The fourth is ten minutes in the sin bin, which the NRL flagged from the rule's first week as the automatic consequence of a professional foul in the ruck.
That ladder is applied unevenly, which is the honest criticism. Different referees find different points on it, and a side defending its line in the seventy-fifth minute of a close game is testing exactly where that point is. The zone rules exist because the ladder alone was not doing the job.
The case against
The strongest objections have been made consistently since 2020 and deserve stating plainly.
It is refereed inconsistently. A ruck offence is a judgement about fractions of a second and body position, and giving referees a cheap sanction encourages them to use it, which multiplies the number of judgement calls in a match.
It cannot be challenged. The captain's challenge and the Bunker do not re-referee a set restart. A wrong call in the seventy-eighth minute stands.
It rewards fitness over craft. Sides that win by physically emptying an opponent are advantaged over sides that win with structure.
It stacked with other changes. The 2021 season combined six again, the extension to offside, the goal-line drop-out change and the two-point field goal, and no one has cleanly separated the effects.
Deliberate concession. The reason the law has needed two zonal adjustments is that teams found it cheap enough to concede on purpose.
The case for
The defence of the rule is narrower but harder to argue with.
The problem it targeted was real and long-standing: defences slowing the ruck and being rewarded with a stoppage. That specific behaviour is now much more expensive across most of the field. Penalties per game fell by roughly a third in the first full season under the extended rule. And the game plainly moves faster in the passages where it matters, which is the reason broadcasters and the commission both backed it.
It is also worth noting what did not happen. The competition did not become unrecognisable, scoring settled back within two seasons, and the margin between good and bad teams did not blow out permanently. The rule was a significant adjustment, not a rupture.
Origin, finals and the pressure test
State of Origin is where the rule is tested hardest, because the standard of defence is higher, the players are fitter and the stakes make cynical infringing more attractive. Origin matches under the six again era have produced some of the loudest arguments about whether a restart is a sufficient deterrent when a side is defending its line in the last ten minutes of a decider.
Finals football has the same character. A set restart five metres out in a semi-final is close to a try-scoring opportunity, and a defending side that concedes three in a row is usually conceding points. The two-point field goal from beyond forty metres, introduced in the same period, was designed for exactly these matches.
If you want to watch that pressure in person, Suncorp Stadium in Brisbane is the sharpest venue in the country for reading a defensive line, and the Grand Final is played at Accor Stadium in Sydney.
Super League and the international game
Super League adopted a version of the set restart in 2020 alongside the NRL, and the International Rugby League brought the ruck-infringement restart into the international laws ahead of the delayed 2021 World Cup, on the reasoning that the sport should be refereed almost identically wherever it is played.
Not everything crossed over. The two-point field goal from beyond forty metres, the set restart for offside infringements and the eighteenth man were not recommended for the international laws. So a Test match and an NRL match are close but not identical, and a viewer moving between them will notice the difference in the ruck first.
That divergence is a long-running feature of rugby league rather than an anomaly. The NRL is the strongest competition, it changes its laws most aggressively, and the international game adopts a subset afterwards.
What to watch for at a ground
Sit side-on if you can, roughly level with the twenty-metre line, and watch the defensive line rather than the ball. Three things will tell you whether the rule is doing its job in that particular match.
First, count the tackles between the referee's arm going up and the next stoppage. A side that gets a restart and immediately scores or forces a drop-out is being rewarded properly. A side that gets three restarts and goes backwards is being defended well.
Second, watch the markers. The offence that produces most restarts is a marker who is a fraction slow or a fraction out of square, and it is visible from the stands in a way it is not on television.
Third, watch what happens near the twenty-metre line. Under the 2026 laws that is where the sanction changes character, and both sides know exactly where the line is.
A worked example, tackle by tackle
The abstraction is easy to lose, so here is what a restart actually looks like from the moment the ball is played.
- Tackle threeA middle forward is tackled thirty-five metres out and the tackler is slow to release him.
- The callThe referee rotates one arm above his head and calls six again. No whistle sounds and nobody stops running.
- Tackle oneThe dummy half plays on immediately, because the defensive line in front of him has one man still getting to his feet.
- Tackles two and threeThe attacking side runs the same two middle carries it would use to start any set, but forty metres further upfield than it would normally be.
- Tackle fourThe halves shift the ball wide against a defence that has now made nine tackles without a pause.
- The outcomeEither the side scores, forces a goal-line drop-out, or kicks on the fifth from a much better position than it held thirty seconds earlier.
A representative sequence rather than a record of a specific match. It shows the decision points, not a guaranteed result, and any of these steps can end in an error instead.
The point of the sequence is the second row. Nothing dramatic happens at the moment of the call. The advantage accumulates over the next four or five tackles, in a defensive line that never got its twenty seconds.
The rule below first grade
The set restart is not confined to the NRL. It applies across the pathway competitions that feed it — the Queensland Cup, the New South Wales Cup, the under-19s and the state-based junior representative competitions — and in the NRL Women's Premiership, which has been played under the same core interpretations since the rule came in.
That consistency matters more than it sounds. A hooker coming through the Queensland Cup arrives in first grade having played several seasons in a game where ruck speed is the primary currency, and a defensive middle forward arrives having been coached to make repeat efforts without expecting a stoppage. The players entering the NRL now have never played senior rugby league under the old law.
Community and junior football uses simplified versions, and local competitions vary in how strictly the ruck is policed, so a parent watching a suburban match in Sydney or Brisbane should not expect NRL interpretations. The principle is the same; the tolerance is wider.
Where the rule goes next
Every adjustment since 2020 has moved the boundaries rather than questioned the mechanism, and the 2026 change widened the restart zone rather than narrowing it. That is the clearest signal available about the direction of travel.
The unresolved question is the last twenty metres. A defending side on its own line still has a rational reason to infringe, because a penalty there is worth more to it than a set restart would be, and no zonal rule has yet made that calculation go away entirely. Whatever comes next is most likely to be aimed at that specific patch of grass.
