Skipper Watson was fined 20 per cent of his match fee while his players received 10-per-cent fines.
Adelaide: Australia were on Thursday fined for maintaining a slow over-rate during its 16-run win over Sir Lanka in the third and final ODI of the best-of-three finals of the tri-series here on Thursday.
Chris Broad of the Emirates Elite Panel of ICC Match Referees imposed the fines after Australia were ruled to be one over short of its target when time allowances were taken into consideration.
In accordance with the ICC Code of Conduct regulations governing minor over-rate offences, players are fined 10 per cent of their match fees for every over their side fails to bowl in the allotted time, with the captain fined double that amount.
As such, Australia's stand-in captain Shane Watson was fined 20 per cent of his match fee while his players received 10-per-cent fines.
If Watson is found guilty of one more minor over-rate offence in ODIs over the next 12 months, he will receive a one-match suspension as per the provisions of the ICC Code of Conduct.
The offence is contrary to Article 2.5.1 of the code which relates to minor over-rate offences.
