Australia, renowned for their steely competitiveness on-field chatter, have issued a new code of conduct for players. In the most extreme instance, a player could receive a life ban if found guilty of racial or religious abuse.
Fines and suspended sentences will be handed out for dissent towards an umpire or for appealing excessively.
Cricket Australia's Peter Young said the code was reviewed annually and aimed to improve the spirit of cricket.
He told the BBC Sport website: "There are a series of codes which we expect our players to adhere to.
"They are reviewed annually and we are aiming to get them more in line with the ICC code of behaviour.
"They also provide more clarity and definition for players so that if they are charged with an offence they know what the penalty will be.
"It is true the harshest penalty a player can receive is a life ban.
"That would be the punishment if a player used language which seriously offended, insulted, humiliated, intimidated or threatened another on the grounds of race, religion, colour or ethnic origin."
The impetus for the crackdown was Australia bowler Glenn McGrath and West Indies batsman Ramnaresh Sarwan ugly spat during a Test match in Antigua in May.
Aussie Test skipper Steve Waugh and Windies counterpart Brian Lara were also involved in heated discussions.
That led to Australia coach John Buchanan urging the team to cut down on sledging if they wanted to earn maximum respect.
Young added: "We have upgraded our spirit of cricket initiative because it is an important issue if we want to attract more children into the game."
The tough penalties will come into force for the new (southern) summer season following discussions this week between Cricket Australia and players at first-class and national level.
