Tim Paine acknowledged he needed to "set a better example" for those watching on after the Australia captain was fined for showing dissent at an umpiring decision in the third Test against India.
India managed to lose just three wickets as they secured a draw on a dramatic final day in Sydney, leaving the series delicately poised at 1-1 with the one game to play.
Australia missed chances in the field and wicketkeeper Paine, who dropped three catches behind the stumps, became involved in a verbal exchange with India's Ravichandran Ashwin that was caught on the stump microphone.
However, he was punished by the International Cricket Council for an incident that happened on the third day, having questioned a decision to umpire Paul Wilson.
Paine - who was fined 15 per cent of his match fee, as well as having one demerit point added to his disciplinary record - admitted the offence, making clear in his post-match press conference that he did not mean to be disrespectful to Wilson.
"We all know that the stump microphones are part of the broadcast. It's great to bring the viewers that close, [for them] to be able to hear it," he told the media.
"I probably set a pretty poor example with my use of language. I'm certainly disappointed with myself after I heard that.
"We know we've got to be careful. I've known and had Paul umpiring me for some time, I certainly didn't mean to be disrespectful to him. It was just a heat-of-the-moment audible obscenity, I think that's what I've been done for.
"I need to be better than that. I know that the stump mics are on and I know it's part of the game.
"There are lots of kids watching the Australia Test team - I need to set a better example than that."
Paine's frustration came after a not out decision by on-field umpire Wilson following appeals for a catch at short leg, with the call not being overturned following the use of the DRS.
Addressing the incident again later in his media duties, he said: "I think we do want to take the game as close to the fans and spectators as we can. At times, when the stump mics are on, that's going to happen.
"We try our best but we are not perfect. If the worst thing we have done is let the odd f-bomb go, then I think we're doing okay."
Australia and India now move on to Brisbane for the series decider, with the fourth Test going ahead after the Board of Control for Cricket in India received assurances over quarantine restrictions amid the ongoing coronavirus pandemic.
