The 1981 Underarm Incident and the Rule It Created

On the evening of 1 February 1981, with one ball left in a one-day international at the Melbourne Cricket Ground, the Australian captain Greg Chappell walked to his younger brother Trevor and told him to bowl it along the ground. New Zealand needed six runs from that delivery to tie the match. Rolled underarm, the ball could not be hit for six by anyone. Trevor bowled it, Brian McKechnie blocked it and threw his bat away, Australia won by six runs, and Australian cricket acquired the moment it has never been allowed to forget. The underarm bowling incident is the most discussed single delivery in the country's cricket history, and the reason a specific line now exists in the Laws of Cricket.

The essential answer to the question everyone asks is that it was legal. Nothing in the Laws in 1981 obliged a bowler to deliver the ball overarm, and the tournament's own playing conditions did not close the gap either. That is precisely why the reaction was as large as it was. If Chappell had broken a rule, the umpires would have dealt with it and the game would have moved on within a week. Instead he demonstrated that the rulebook had a hole in it, and cricket had to decide whether to fill the hole or admit that its idea of fair play was decorative.

What follows is the whole episode: the tournament, the state of the match, the over ball by ball, why the delivery was permitted, what everyone said, what happened to the finals series afterwards, and the exact wording of the law the incident produced.

The tournament nobody remembers

The match was the third final of the Benson and Hedges World Series Cup of 1980-81, the limited-overs tournament that had grown out of the World Series Cricket split and had by then been absorbed into the official Australian summer. Australia, New Zealand and India played a long round-robin through December and January, and the top two met in a best-of-five finals series. Australia and New Zealand qualified.

The format matters to the story. A best-of-five finals series in a crowded Australian summer meant the players were deep into a punishing schedule by the start of February, moving between Sydney and Melbourne on consecutive days with Test cricket wrapped around it. Greg Chappell has cited that workload ever since as the context, though never as the excuse, for what he did.

New Zealand won the first final at the Sydney Cricket Ground on 29 January. Australia levelled the series at the Melbourne Cricket Ground on 31 January. Twenty-four hours later, the two sides were back at the same ground for the third.

The state of the match

Australia batted first and made 235 for 4 from their fifty overs. Greg Chappell scored 90 of them. New Zealand's reply was built around Bruce Edgar, who batted through and finished unbeaten on 102 — a century that is almost certainly the least remembered hundred ever made in an Australian one-day international, purely because of what happened at the other end while he was standing at the non-striker's end.

The crowd was about 52,990, a record for a one-day international at the time and a reminder that the tournament was, commercially, working exactly as intended. Television had made the format enormous in Australia inside four years, and the audience watching at home was very much larger again.

New Zealand needed fifteen runs from the last over. Trevor Chappell, a part-time medium-pacer, was bowling his tenth.

The final over, ball by ball

The over ran like this. The first ball went for four. The second removed Richard Hadlee, leg before. The third and fourth went for two apiece. The fifth bowled Ian Smith. That brought Brian McKechnie in at number ten with one ball remaining and six runs required to tie.

At that point Greg Chappell walked in from the field, spoke to his brother, and told him to bowl underarm. Under the Laws as they then stood, a change in the mode of delivery had to be notified to the umpire, who in turn informed the striker, and it was. Umpire Don Weser told McKechnie what was coming. Peter Cronin was the other umpire. Rod Marsh, keeping wicket, is widely reported to have called out to his captain that he should not do it.

Trevor Chappell then bowled the ball along the ground. McKechnie put his bat in front of it, then threw the bat away. The Australian fielders did not celebrate. Neither, in any meaningful sense, did the ground.

A sequence of events rather than a set of measurements. Each step is drawn from the published scorecard and contemporary accounts of the over.

Why it was legal

The Laws of Cricket had never specified that the ball must be bowled overarm, for the simple reason that when they were first codified underarm was the only way anyone bowled. Roundarm arrived in the 1820s and 1830s and overarm was legalised in 1864. Underarm bowling did not become illegal at that point. It simply became obsolete. Bowlers stopped doing it because it did not work, and the Laws had no reason to ban a technique nobody used.

By 1981 the last serious underarm bowler in first-class cricket was more than a century in the past. The absence of a rule was not a loophole anyone had spotted and preserved. It was an oversight nobody had noticed because nobody had ever had a reason to look.

The World Series Cup's own playing conditions, which modified the Laws in various ways for the limited-overs format, did not close the gap either. So when Chappell decided that a six was unacceptable, the umpires had nothing to work with. They could require notification of the change, and they did. They could not refuse it.

The catch that set the mood

The final over did not happen in a neutral atmosphere. Earlier in the day, Greg Chappell had been on 58 when he hit a ball to the deep where Martin Snedden appeared to take a running catch. The New Zealanders were certain of it. The umpires had been watching the batters complete their runs rather than the fielder, could not give a decision they had not seen, and Chappell stayed. He went on to 90.

That sequence matters to understanding the size of New Zealand's reaction. From their point of view the match had already been shaped by an incorrect non-decision that favoured the Australian captain, and then the same captain removed their last chance of a tie. Whether or not the catch was clean, it explains why the New Zealand dressing room reacted with fury rather than disappointment. Warren Lees later described the room as too angry for words, its silence broken by a smashed tea cup.

What was said, and by whom

Richie Benaud was on air for Channel Nine and delivered the summary that has outlasted everything else about the match. He called the delivery disgraceful and one of the worst things he had ever seen done on a cricket field. Benaud was a former Australian captain speaking on Australian television immediately after an Australian victory, and his verdict effectively settled the domestic argument before it started. There was no significant constituency in Australia arguing that the delivery had been a good idea.

Ian Chappell, the eldest of the three brothers and himself a former Australian captain, was also commentating and can be heard objecting in real time as the field was set.

Robert Muldoon, New Zealand's prime minister, called it the most disgusting incident he could recall in the history of cricket, described it as an act of true cowardice, and observed that it was appropriate the Australians had been wearing yellow. Malcolm Fraser, Australia's prime minister, said it was contrary to all the traditions of the game. Two heads of government commenting on one delivery within a day of it being bowled is, as far as the sport goes, unique.

What happened to the finals series

Australia went 2-1 up and closed out the series in Sydney on 3 February. They won the finals 3-1 and took the trophy. This part of the story is almost never told, because the result of the tournament turned out to be the least significant thing about it. The match is indexed in every archive by what happened on the last ball rather than by who won.

There is a small irony buried in that. The delivery was bowled to protect a lead in a series Australia then won comfortably anyway. Had Trevor Chappell bowled a normal ball and McKechnie somehow found six, Australia would have had a tie, still been level at 1-1 in the finals, and in all likelihood still have won the tournament two days later. The cost-benefit calculation that produced the most notorious ball in Australian cricket was, on the evidence, not even a good one.

The law that came out of it

The International Cricket Council moved quickly, banning underarm bowling in international cricket on the basis that it was not within the spirit of the game. The Marylebone Cricket Club subsequently wrote the prohibition into the Laws themselves, where it has remained through successive rewrites.

Under the current code, Law 21.1 deals with modes of delivery. Law 21.1.1 requires the bowler to tell the umpire whether he or she will bowl right or left handed and over or round the wicket, and requires the umpire to pass that on to the striker. Law 21.1.2 states plainly that underarm bowling shall not be permitted except by special agreement before the match. Law 21.3 then supplies the sanction: if the umpire considers the ball has been delivered underarm without that agreement, the umpire calls and signals no ball.

The practical consequence is that a modern captain trying the 1981 tactic would achieve nothing at all. The no ball would concede a run, the ball would have to be bowled again, and the free hit provisions in limited-overs playing conditions would make the situation worse than it had been. The hole is properly filled.

Why the agreement clause exists

The exception for special agreement before the match looks odd until you remember that the Laws of Cricket govern village greens and school ovals as well as internationals. A social match in which one player has an injured shoulder, or a charity fixture with a novelty format, can agree to underarm bowling in advance. The clause preserves that possibility while removing any chance of a captain springing it on an opponent in the middle of an innings, which was the entire problem in 1981.

The umpires had no move to make

It is worth being clear about the position Don Weser and Peter Cronin were in, because they are sometimes blamed for allowing the delivery. They could not have stopped it. The Laws of the day contained no prohibition, the tournament playing conditions contained no prohibition, and an umpire has no general power to disallow a legal act because it seems unsporting. Their duty was procedural: to be told of the change in the mode of delivery, and to pass that information to the striker. Both did exactly that.

One footnote to the over is that at least one Australian fielder is reported to have been out of position when the ball was released, which under a strict reading should have produced a no ball for an illegal field. It has never been established, and it would have changed the arithmetic rather than the argument. The moral question was decided the instant the captain gave the instruction, not by where a fielder was standing.

The spirit of cricket, written down at last

Cricket now carries a preamble to the Laws headed the Spirit of Cricket, setting out expectations of captains, players and umpires that sit outside the numbered Laws. It was introduced in the 2000 code, nineteen years after Melbourne, and it is not a response to a single incident. But it is a response to a category of problem the underarm ball defined more sharply than anything before it: behaviour that is technically permissible and obviously wrong.

The preamble does not carry the same force as a Law, and that limitation is deliberate. Its purpose is to state what the game expects rather than to punish. Australian cricket has since discovered, more than once, that a statement of expectations is a weaker instrument than a numbered clause with a sanction attached. The 1981 response — ban the specific act, define the specific penalty — remains the more effective of the two approaches, which is why the delivery is now a no ball rather than merely a matter of regret.

The long aftermath for the Chappells

Greg Chappell continued to captain Australia and finished with a Test record that puts him among the country's greatest batters. He has never tried to argue the decision was defensible. His consistent explanation is that he was mentally and physically finished by that point in the season, that the pressure of a relentless schedule had accumulated, and that his frustrations boiled over. He has said in later interviews that he should not have been on the field.

Trevor Chappell had a modest international career and has spent the decades since being asked about one ball he was told to bowl by his captain, who was also his older brother. He has generally declined to expand on it. The consensus in Australian cricket is that the person who carried the least responsibility has carried the most of the memory.

Brian McKechnie's position has been the most generous of the three. He has said repeatedly that he holds nothing against either brother and that the incident was not their finest moment but does not define them. He also had the unusual perspective of a genuine dual international, having played rugby union for New Zealand as well as cricket, which may have given him a wider sense of proportion than most of the people arguing on his behalf.

New Zealand's reply, and a bowls wood

Australia toured New Zealand the following year. When Greg Chappell came out to bat at Eden Park in front of a crowd of around 43,000, someone rolled a lawn bowls wood onto the field. It was a good joke, and Chappell responded by scoring a century in a losing cause. The gesture became part of the folklore on the New Zealand side of the Tasman in a way the Australians have never quite matched, because in Australia the incident is an embarrassment and in New Zealand it is a grievance with a punchline attached.

For a generation, the underarm ball supplied the emotional charge in a fixture that otherwise struggled for one. Australia won most of the cricket. New Zealand had the moral high ground and a piece of footage. Those are not equivalent, but they are both durable. Anyone reading the wider Australia versus New Zealand cricket rivalry will find the underarm ball sitting under almost every meeting between the two sides for the next twenty-five years.

The 2005 re-enactment

The first men's Twenty20 international ever played was Australia against New Zealand at Eden Park on 17 February 2005, a match in which both teams wore retro kit and the whole occasion was played with a straight face only occasionally. Late in the game Glenn McGrath mimed an underarm delivery to Kyle Mills and the New Zealand umpire Billy Bowden produced a red card. The crowd laughed.

That was the moment the incident formally moved from open wound to shared joke, twenty-four years after the fact. It could not have happened earlier, and it required a New Zealand umpire and a New Zealand crowd to make it land. An Australian attempting the same gag in 1990 would have been run out of the country.

How the incident is used in Australia now

The underarm ball has become the standard Australian reference point for the difference between what the rules allow and what the game will tolerate. It gets invoked in three recurring situations.

The first is any sharp but legal piece of play: a run-out at the non-striker's end, an appeal that is technically correct and socially awkward, a declaration timed to deny an opponent something. The second is any formal discussion of the spirit of cricket, a phrase that now appears in the preamble to the Laws partly because the sport learned in 1981 that unwritten expectations do not enforce themselves. The third is any close finish between Australia and New Zealand, where a commentator will reach for it within about ninety seconds.

It also functions as a lesson in administration: if a behaviour is unacceptable, put it in writing. Cricket Australia's own governance and playing conditions have been rewritten many times since, and the general drift has been toward specifying things that were once assumed. Readers following the broader institutional story will find it in the history of Australian cricket and in the account of where the game began in Australia.

The backyard afterlife

The one place in Australia where underarm bowling survived the ban is the backyard, and there it acquired a specific meaning. Rolling the ball at a younger sibling to stop them scoring is understood, in every Australian backyard, as a reference — and as cheating in the specific 1981 sense rather than the general one. It is one of a very small number of cricket incidents that produced a piece of everyday Australian language.

Backyard cricket has its own unwritten code, and part of the reason the code is unwritten is that most of it is impossible to enforce. That is the joke the 1981 incident keeps supplying. Tip and run, one hand one bounce, over the fence is out and you fetch it — none of it works unless everybody agrees it works. The code holds right up until somebody decides it does not apply to them.

What a modern equivalent would look like

Because the specific tactic is now impossible, the interesting question is what its equivalent would be. The honest answer is that the modern versions are all things that were already legal and have since become normalised: slow over rates managed to the edge of the penalty, fields set to concede a single and protect the boundary, bowlers aiming so wide of off stump that the wide law becomes the contest, and the running out of a non-striker who has left the crease early.

None of those carry the visceral quality of a ball rolled along the ground, because none of them are visible in a single frame. That is part of why the underarm delivery has lasted. It requires no explanation. A person who has never watched cricket can be shown five seconds of footage and understand exactly what has happened and exactly why people are upset.

Checking the record for yourself

Three things are worth verifying directly rather than trusting a retelling. The scorecard for the third final gives the innings totals, the fall of wickets and the bowling figures, and confirms that New Zealand needed six to tie rather than to win, a detail that gets misstated constantly. The Marylebone Cricket Club's published Law 21 gives the current wording on modes of delivery and the no-ball sanction, which is short and unambiguous. And the original Channel Nine footage carries Benaud's commentary, which is the primary source for the most quoted reaction to the delivery.

Almost everything else in circulation — the exact words used in the middle, the precise sequence of who said what to whom — is reconstructed from memory, and the accounts differ. That is normal for an event forty-five years old. It is also a reason to be careful with any version that quotes the participants word for word, including the versions that appear in otherwise reliable places.

Where this sits in the Australian summer

The incident happened at the MCG in the depths of a domestic season that today would look familiar in shape and unrecognisable in detail. There was no Big Bash League, no Twenty20 cricket of any kind, no neutral umpires and no television review. The tournament that produced the underarm ball was itself only four seasons old, and the idea that a limited-overs final could carry that much weight was still novel in Australian cricket.

Today the equivalent occasion would be a Boxing Day Test or a white-ball final broadcast to a far larger audience with a far larger apparatus of officials, replays and post-match analysis. Whether that apparatus would have prevented the delivery is doubtful, since nothing about it was hidden, but it would certainly have shortened the argument, because a modern umpire would have called no ball and the match would simply have continued.

For the broader picture of how Australia's summer fits together across formats and competitions, the guide to following cricket in Australia covers the current schedule, and the cricket section collects the rest. The rivalry that produced the incident has its own long history, as does the other great modern Australian Test contest set out in the Border-Gavaskar Trophy guide, and the oldest of them all is described in the Ashes guide. The Australia hub links the venues and the competitions together.

Why the story keeps its size

Forty-five years on, the underarm incident retains its scale for a reason that has nothing to do with cricket tactics. It is the rare sporting controversy where the facts are undisputed. Nobody argues about what happened, nobody claims the footage is ambiguous, and the person responsible has never defended it. There is no counter-narrative to litigate, no conspiracy to unpick, no second camera angle that changes anything.

What remains is a single, clean question that any sport can be asked: if something is not forbidden, is it therefore allowed? Australian cricket answered that question in public, at speed, in front of about 52,990 people and a national television audience, and did not much like its own answer. The law that followed exists because the answer was no.
