At the end of the day, I can see why India do feel Australia are bad sports. Look at the Past events. All the events in the past portray Australia's bad sportmanship and arrogance:
Remember:
-When an Australian player did an underarm bowl to ensure they won the match against NZ
-Shane Warne took Drugs
-Ricky Ponting getting into a fight at a nightclub while drunk
Look at these 'controversies on wikipedia about Ricky Ponting(the list is long)
Controversies
Ponting was involved in a fight outside a pub in Kings Cross, New South Wales in early 1999, and earned a suspension from the national team.[43]
During Australia's tour of India in 1998, Ponting was reportedly thrown out of Equinox night club in Calcutta. The Indian papers reported that Ponting was misbehaving with several women in the nightclub. Ponting was fined for this incident, and later apologised to the nightclub staff.[44]
During the 4th Test of the 2005 Ashes series, at Trent Bridge, Ponting was angrily outspoken about the use of substitute fielders by the England side, particularly after being run out by such a substitute. He directed an abusive tirade at the England dressing room and was subsequently fined 75% of his match fee.[45]
After England won the match to take a 2-1 lead in the series Ponting returned to the subject of substitutes in an interview with Australian radio "I think it's an absolute disgrace the spirit of the game is being treated like that. It is within the rules; it's just not within the spirit of the game" he said. The England coach Duncan Fletcher later commented on this incident: "He [Ponting] completely blew his top. I did not actually think it at the time but, looking back now, that might be the moment when it became clear that England were going to regain the Ashes."[46]
In 2005 he began using cricket bats with a graphite covering over the wooden blade of the bat. This covering was ruled by the MCC to have contravened Law 6.1, which states that bats have to be made of wood, although they may be "covered with material for protection, strengthening or repair not likely to cause unacceptable damage to the ball". Ponting and his bat supplier, Kookaburra Sport, agreed to comply.[47][48]
Ponting has been fined for dissent on more than one occasion.[49]
After the final of the 2006 ICC Champions Trophy, Ponting drew some criticism for appearing to ask BCCI president Sharad Pawar to "leave the podium" so his team could commence celebrations. The issue, while minor, was solved when Ponting issued a formal apology to Pawar.[50][51]
After the 2nd Test of 2007-08 series against India, Ponting and the Australian Cricket team were criticized by the media and several former and present cricket personalities, for playing the match contrary to the spirit of the game. [52][53][54]. The Sydney Morning Herald went on with the headlines, Arrogant Ponting must be fired.
