Makhaya Ntini was among the players targeted in Perth

Cricket Australia (CA) has announced the measures after South Africa players complained about being targeted by fans during the first Test in Perth.

Authorities already had the power to evict supporters in such circumstances.

But stewards in Perth did not take action because they were unfamiliar with the words shouted by a section of the crowd.

According to reports, the players were taunted with the terms 'kaffirs' and 'kaffir boeties', derogatory terms for black people and those sympathetic to them.

CA are determined to take a tough line and chief executive James Sutherland said there was even the possibility of permanent bans being imposed.

Our guys are pretty upset about it, something needed to be done Graeme Smith

"I understand overseas there are various methods they have from banning people to go to soccer matches for example," he said.

"I would hope that sport in Australia doesn't need to get to that stage but if we do have serious problems, some of the serious problems they have had overseas, obviously some of these measures would be well supported by us."

South African captain Graeme Smith welcomed the changes, saying: "Our guys are pretty upset about it, something needed to be done.

"We expected to cop a bit of abuse but this was pushing the limits."

Cricket South Africa chief executive Gerald Majola added: "This evil has to be stamped out wherever it is found, and all must unite against it.

"Our players need to be protected against racism, and we hope that these new measures will ensure this."
