3. Underarm bowling incident
The underarm bowling incident of 1981 took place on 1 February 1981, when Australia was playing New Zealand in a One Day International cricket match, the third of five such matches in the final of the Benson & Hedges World Series Cup, at the Melbourne Cricket Ground.
To prevent New Zealand from any chance of scoring the six they needed to tie, the Australian captain, Greg Chappell instructed his bowler Trevor Chappell to deliver the last ball underarm, along the ground.
This action was legal at the time, but nevertheless seen as being against the spirit of cricketing fair play.
4 No-balling Muralitharan for throwing 
In a 1995 match between Australia and Sri Lanka in Melbourne, umpire Darrell Hair no balled Muttiah Muralitharan seven times in three overs for throwing.
It was the first time Muralitharan had been called in 22 Tests, although the ICC later said that umpires had expressed doubts about his legitimacy for more than two years.
Biomechanical investigation of Muralitharan's action conducted at the behest of the ICC concluded that a congenital elbow deformity was partly responsible for his unusual action and his arm remained bent throughout delivery of the ball. After further review by an expert panel, the ICC decided to raise the elbow extension limit to 15 degrees for all bowlers.
In 1999 Hair was found guilty by the ICC of bringing the game into disrepute after he described Muralitharan's action as "diabolical". Hair later received death threats that referenced the throwing incident and as a result the ICC decreed that he would not officiate any of Sri Lankas matches at the 1999 World Cup. Hair still believes Muralitharan's bowling action is suspect.
