The cost will include $91.2 million for the royal commission and $40 million for the department to support the inquiry.
The hearing was told 89 staff would be allocated to the royal commission, 64 for the inquiry itself and 25 from the Attorney-General's Department.

"I certainly understand in terms of the terms of reference, there is an avenue there."
