Sharma was fined for using inappropriate language after dismissing Smith during Australia's first innings on the third day at the Gabba.
According to a media release sent by ICC,"Sharma has been fined 15 per cent of his match fee for violating Level 1 Article 2.1.4 of the ICC Code of Conduct for Players and Player Support Personnel, which relates to "language or a gesture that is obscene, offensive or insulting during an International match."
All Level 1 breaches carry a minimum penalty of an official reprimand and a maximum penalty of 50 per cent of a player's match fee.
ICC Match Referee Jeff Crowe imposed the fine on Australia after Smith's side was ruled to be three overs short of its target when time allowances were taken into consideration.
As such, Smith has been fined 60 per cent of his match fee, while his players have received 30 per cent fines. If Smith is found guilty of one more minor over-rate offence as captain in Tests over the next 12 months, he will receive a one-match suspension as per the provisions of the Code.
