Dubai: Australia's Brad Haddin and Shane Watson have been penalised for showing dissent at umpires' decision during their seven-wicket defeat at the hands of Pakistan in the one-off Twenty20 international cricket match on Thursday.

While wicket-keeper batsman Haddin was fined 15 per cent, all-rounder Watson will have to do away with 25 per cent of his match fees for breaching the ICC Code of Conduct.

In a hearing convened after the game by ICC match referee Jeff Crowe, both the players pleaded guilty to contravening Level 1.3 of the ICC Code of Conduct for Players and Team Officials which relates to 'showing dissent'.

The first incident took place in the fifth over of the Australia innings when Watson was given out lbw by umpire Aleem Dar. The all-rounder showed dissent by gesturing towards and hitting the bat against his hand. He also continued to make verbal and physical signs of dissent as he walked off the field.

The next incident occurred in the eighth over when Haddin, at non-striker's end, pointed his bat towards umpire Zameer Haider when Andrew Symonds was given out lbw. The Australia stand-in captain also claimed to the umpire that 'there was bat involved'.

"Both players immediately pleaded guilty to the charges and were very apologetic about their actions. While I understand that players will feel frustrated at times, both Brad and Shane were quick to acknowledge that they needed to accept the umpire's decision without gesture or verbal complaint," Crowe said in a statement.

All Level 1 breaches of the ICC Code of Conduct carry a minimum penalty of an official reprimand and a maximum penalty of 50 per cent of a player's match fee.

The charge was brought to notice by on-field umpires Dar and Haider as well as third umpire Nadeem Ghauri.

Apart from the players and the on-field umpires, the hearing was attended Australia team manager Steve Bernard.
