Dwayne Bravo has been fined 20% of his match fee for breaching Level I of the ICC Code of Conduct by showing dissent at the umpire's decision during the first ODI between West Indies and Australia in St Vincent.

West Indies were chasing 279 and were at 80 for 3 in the 20th over when Asad Rauf gave Bravo leg before off Michael Clarke. Bravo stayed at his crease after being given out and then walked off shaking his head.

Roshan Mahanama, the match referee, penalised Bravo, who had pleaded not guilty, and said when the umpire's finger goes up, the batsman must go without delay regardless what he thinks of the decision.

"That is one of cricket's most fundamental principles and Bravo's failure to adhere to that principle, especially given the message his action sends out to the millions of people watching both at the ground and on television, merited some form of action," Mahanama said.
