Former judge Tony Fitzgerald has the power to broaden the scope of his inquiry into Queensland's Crime and Corruption Commission, but the state government won't order him to do so.
Premier Annastacia Palaszczuk has appointed Mr Fitzgerald, who led a landmark 1987/89 inquiry into corruption in Queensland leading to the CCC being established, to review the watchdog.
Former judge Alan Wilson QC has also been chosen for the Commission of Inquiry which will review the watchdog's structure and functions, and its use of police officers.
Amid political calls for a wider inquiry into government integrity, Ms Palaszczuk says the terms of reference are now up to the commission and the government won't be interfering.
"That's a matter for them, honestly that is a matter for them," she told reporters on Tuesday.
The inquiry has been ordered in response to a December parliamentary report which called for a royal commission into the CCC after its bungled 2019 probe into Logan Council.
The Parliamentary Crime and Corruption Committee, chaired by Liberal National Party MP Jon Krause, launched a probe into the CCC in April after prosecutors dropped charges against the former Logan mayor and seven councillors due to a lack of evidence.
All eight lost their jobs, and the report said the watchdog's chair Alan MacSporran hadn't ensured that the CCC acted "independently and impartially" during the episode.
Mr MacSporran resigned last week, saying his relationship with the committee had "broken down irretrievably".
The LNP, the Katter's Australian Party and the Greens want the new Fitzgerald inquiry to be broadened to probe all government integrity.
The calls come after the resignation of Integrity Commissioner Nikola Stepanov, who has complained of "interference" in the funding and resourcing of her office.
The CCC is also probing allegations the Public Service Commission confiscated a laptop from Dr Stepanov's office and wiped its contents without her knowledge or permission last year.
Meanwhile, former state archivist Mike Summerell has alleged he was driven out of his role last year after being forced into "misleading parliament" for two years.
Opposition Leader David Crisafulli said the premier must order the Fitzgerald inquiry to probe the allegations involving the archivist and the integrity commissioner, and not just the CCC.
"Yesterday, the premier thought that announcing one element would be enough to hose out the fire, but it's not, and Queenslanders have seen through it," he told reporters on Tuesday.
"And this time the media management of it will have to make way for a bigger inquiry."
However, the premier maintained that the Fitzgerald inquiry had been set up to deal with matters raised about the CCC.
"It is wrong for me to comment on what Mr Fitzgerald may or may not do. Let the commission get on with their job," Ms Palaszczuk said.
"I fully support the commission, it is a royal commission, it is a royal commission, and they are checking to ensure that the CCC is operating in the best interest of Queensland."
