A senior official of the board said Wasim had conveyed to the board he would be available now on for the hearings.
He will be attending the hearing of the committee scheduled on Wednesday, the official said.
The committee which is headed by Pakistan Cricket Board chief operating officer Wasim Bari and includes team manager Yawar Saeed and PCBs legal advisor Tafazzul Rizvi, has held two hearings in which it has questioned coach Intikhab Alam, former manager Abdul Raquib, assistant coach, Aaqib Javed and some players.
Reports said the two hearings have confirmed that there were some disciplinary issues in the team and a communication breakdown had occurred between the management and some senior players.
Some of those who appeared in the hearings did give credence to the allegations made by (Mohd) Yousuf that Shoaib Malik proved to be a difficult character to handle in Australia, the reports added.
Pakistan were whitewashed in all three formats of the game during the dreadful tour Down Under.
