Harbhajan Singh was initially found guilty of racially abusing all-rounder Andrew Symonds in the acrimonious second Test in Sydney.
A stand-off between the teams was ended after the charge was downgraded on appeal to using abusive language and the bowler let off with a fine.
Earlier this year, Harbhajan was banned for five one-day international matches for slapping team-mate Sreesanth during an Indian Premier League match.
The off-spinner said he had learnt from his past mistakes and was looking to focus on the game.
"I aim to let the ball do the talking this time," he told the reporters.
"It's better to focus on the game and avoid all the drama.
"I'm very passionate. I try and give it my best shot all the time and I get too involved.
"When someone says something to me, I take it very personally.
"But I have learnt that it is better to bowl well, take wickets, play the game hard and win the game rather than say something in return or react to what someone else says."
Harbhajan is relishing the chance to face Australia again.
" Australians are very competitive side and I am looking forward to playing them" he added.
"But, I'm looking forward to playing them and I'm sure this will be another great series.
"Hopefully we will all play in the spirit of the game and enjoy the series."
The Punjab player has had particular success against the Australians, picking up 32 wickets in the memorable three-Test series in 2000-01 in India.
"There is always the motivation to do well against the number one team in the world," he said.
"They keep throwing you challenges and you have to respond to it.
"But we believe that they can be beaten and we have proved that in the past - we have beaten them at home and in Australia as well - and we have the capability and the talent to beat them.
"We would have to play to the best of our ability and that is what I am looking to do."
