On Monday, the Pakistan Cricket Board (PCB) chairman, Khalid Mehmood had asked Australian team captain Mark Taylor and batsman Mark Waugh to appear at a judicial inquiry into bribery allegations against senior Pakistani players.

But the ACB chief Speed has ruled out any such possibility. He said on Tuesday that his players would not be available on the current tour. Sports observers say that a telephonic conversation between Speed and PCB chief executive, Majid Khan, on Monday did not go well. Khan told Speed that he was helpless before the commission.

Speed in a statement on Tuesday said: ``TheAustralian team is in Pakistan to play cricket and its first commitment is to the opening Test match starting in Rawalpindi on Saturday.''

Waugh, who with Tim May and Shane Warne, accused Salim Malik of attempted bribery on Australia's previous tour of 1994, will be asked to substantiate his allegations by the judicial inquiry. Both Waugh and Taylor said they would be available for the inquiry hearing provided their cricket board approves their appearance before it.

The Australians have never attended a hearing in Pakistan to discuss their 1994 allegations against Malik. PCB chairman Mehmood told reporters that the chance to appear now is ``a good offer to substantiate the allegations of four years ago.''

But the ACB is not interested in the appearance of its players before a commission that only has hearings on Saturdays. This interferes with the schedule of the touring Australian side. The ACB is claiming that their players have diplomatic immunity while in Pakistan, meaning the commission has nopower to force them to appear.
