Fine Cotton Ring-in, Eagle Farm, August 18, 1984

Officials' suspicions were raised before the running of the Second Commerce Novice when poorly performed racehorse Fine Cotton was sensationally backed in a plunge which would have netted more than $1.5 million.

After looking beaten Fine Cotton fought back and won by a short half head. As the horse was returned to scale, restless punters yelled "ring-in, ring-in".

Stewards, accompanied by police, checked the horse's brands and learned he was not Fine Cotton but the better credentialled Bold Personality.

The horse was disqualified and one of the greatest scandals in Australian racing history was uncovered.

Second Rugby Test, Australia v New Zealand, Ballymore, July 19, 1992

It was just before half-time when Australian winger Paul Carozza scored in the corner to give Australia an 11-7 lead but what happened next was to turn the crowd's cheers to howls of indignation.

As Carozza lay on the ground after scoring the try, All Blacks prop forward Richard Loe, running across at full pace, dropped on him, smashing Carozza's nose with his forearm.

While no official action was ever taken against Loe, Carozza had the last laugh. He scored another try in the second half, clinching a two-point win and the Bledisloe Cup.

First Cricket Test, Australia v South Africa, December 11, 1963, The Gabba

Fast bowler Ian Meckiff, an 18-Test veteran, was bowling his first over when square leg umpire Col Edgar no-balled him four times for throwing.

Australian captain Richie Benaud did not bowl him again in the match.

Edgar had seen Meckiff bowl some 119 overs of first-class cricket without a problem. A Board of Control directive to umpires to call any bowler whose action even hinted at illegality, suggested the Victorian quick was being made a scapegoat.

The angry crowd stopped play for two minutes with chants of "We want Meckiff. We want Meckiff". At close of play spectators invaded the ground and chaired Meckiff off, while roundly booing Edgar.

The demonstration was to no avail. Meckiff played out the match then retired from all forms of cricket.

Second Rugby League Test, Australia v New Zealand, June 18, 1985, Lang Park

There were just two minutes remaining when referee Julian Rascagneres sent opposing props Greg Dowling and Kevin Tamati off for fighting.

The on-field dust-up was nothing new for Lang Park: It was the aftermath – a fight on the sidelines – which earned the incident a place in Queensland sporting folklore.

Dowling would later say he had stepped aside to let Tamati go up the tunnel first, fearful of "copping one behind the ear". He put his hand on Tamati's shoulder to push him through, the Kiwi hardman lashed out with an elbow which hit Dowling in the mouth and it was on again.
