NINE people have been summonsed to appear in secret hearings before a commission of inquiry into organised crime.
Attorney-General Yvette D'Ath also told a parliamentary estimates committee that more than 100 requests for written information and documents had been made.
Barrister Michael Byrne will oversee the inquiry, which will examine drug trafficking, extortion, violence, child sex offences and other forms of organised crime.
The Commission of Inquiry will check the adequacy and appropriate nature of responses to organised crime, co-operation between enforcement agencies and the strength of current laws.
"The majority of the submissions and information provided to the commission has been accompanied by requests for confidentiality," Ms D'Ath said.
"In relation to future public hearings, that's really a matter for the commission to determine based on the sensitivities of the matters."
The hearing heard retired Justice Alan Wilson will be paid $250,000 to oversee the review of the state's anti-bikie legislation.
But taskforce members are not being paid to sit on the taskforce.
Kathleen Florian, from the Crime and Corruption Commission, told the estimates committee the watchdog was forced to slash seven full-time positions when funding to tackle bikie gangs ended.
But she said funding to pursue the proceeds of crime would continued for a further year.
