Treasurer Jim Chalmers says he understands people being "filthy" about PwC's leak of confidential tax information, but the government doesn't plan to refer the breach to the corruption watchdog.
A parliamentary committee said in an interim report that PwC engaged in a calculated breach of trust by using confidential information for tax avoidance.
Dr Chalmers said the committee had a number of parliamentary processes it could use to get information, as did investigators from the Australian Federal Police.
"We want to see more transparency, of course, we want to get to the bottom of what's happened here and people should be accountable for their actions," he said.
Asked if the leak should be referred to the new anti-corruption watchdog, Dr Chalmers said he understood people were "filthy" about the breach.
"It's not for us necessarily to refer it," he said.
"It makes a lot of sense to have this committee process running, to have the AFP referral from the Treasury, and all of the other things that we are doing."
Dr Chalmers refused to say whether a list of names of those involved in the leak should be released, which the Greens have previously tried to do.
"We've seen a trashing of the consultation process and it's been deeply disappointing and completely unacceptable," he said.
Greens justice spokesman David Shoebridge called on the government to release a full exchange between AFP Commissioner Reece Kershaw and long-time friend Mick Fuller, a former NSW Police commissioner and partner at PwC, over a contract won by the consultancy firm.
A Senate estimates hearing last month was told Mr Kershaw had received a text message from Mr Fuller about the referral of PwC to the AFP.
"When the Australian Federal Police commissioner is a mate of a senior partner in PwC, how can any of us have faith in the independence of that investigation," Senator Shoebridge said.
He said there were "detailed explanations" required from Attorney-General Mark Dreyfus and from the AFP commissioner as to why a conflict of interest declaration wasn't produced.
Cabinet minister Katy Gallagher described questions relating to the integrity of the AFP as "disappointing".
"The public should have every confidence that just like all serious criminal investigations this investigation into PwC will be undertaken by experienced investigators within the AFP special investigations team," she said.
