A Senate committee is calling on PwC to disclose the "names and positions" of the staff involved in the embattled consultancy firm's controversial tax leaks scandal.

The request forms part of 12 recommendations from a final report by the federal committee that investigated the federal government's use of private consulting services.

The inquiry was launched in the wake of the PwC tax leaks scandal in early 2023, when it was discovered the firm leaked sensitive Australian government information to large corporations, including Google.

Other recommendations in the report include calls for a legal review into the "legislative frameworks" and "structures of partnerships," with a particular focus on partnerships in excess of 100 partners, and new clauses in government contracts that would explicitly require consulting firms to act in the public interest when they are providing services to government.

"The consulting sector has been operating in the shadows way too long," Labor Senator Deborah O'Neill told the ABC.

"Since this inquiry has commenced … on 15 February 2023, we found out so much more about the way this shadowy conglomerates are working in our Australian Public Service," she said.

However, in additional comments appended to the report, Greens senator Barbara Pocock was critical of the way in which the public service has been eroded in recent decades as Australian governments have become over-reliant on consultants, and said the recommendations in the report don't go far enough.

"They do not address the magnitude and scope of the problems this inquiry has uncovered," she argued.

"Specifically they do not address the issue of political donations by big consultants, the revolving door in and out of government, the inadequacy of penalties for PwC, the pressing need for structural reform to cap big partnerships' size, and to address conflicts of interest and the opaque nature of big partnerships."
