Nathan Hauritz is heading for the cricket World Cup with a message from former Australian off-spin great Ashley Mallett to change the way he bowls.

Hauritz has been named as the replacement for Shane Warne and is now set to fly out to South Africa.

The 21-year-old off-spinner received some timely tuition at the Gabba from Mallett, who claimed 132 wickets in 38 tests at 29.84 and is now helping Rod Marsh at the English Cricket Academy in Adelaide.

Mallett worked on Hauritz's action which the young spinner believed had changed during Australia's series against Pakistan in Sharjah last year.

"He tends to bowl around himself a bit, especially in the one day game," said Mallett, who has advised Hauritz since he was a 16-year-old.

"He says he actually bowls differently in one day cricket.

"We tend to differ there in our thinking, then again he's 21 years of age he's only just getting to know himself. By the time he's 25 or 26 he's going to be a hell of a lot better. But that process of getting to know himself is going to take a while.

"He's got to change his thinking. His mindset's gotta change.

"He's got to realise he's good enough to defend and attack in the one package. He'll get there but he'll work it out himself."

Within hours of Warne's 12 month suspension from the game on Saturday, Hauritz received a phone call from Australian chairman of selectors Trevor Hohns telling him to pack his bags for South Africa and the World Cup.
