A whistleblower has claimed a former parole board boss referred to the corruption watchdog had been romantically linked to a Labor staffer, Queensland's opposition says.
Corrective Services Minister Nikki Boyd has been grilled over what she knew about allegations levelled at Michael Byrne, who recently resigned as state parole board president.
Mr Byrne has been referred to Queensland's Crime and Corruption Commission over allegations he misused travel funds.
He is not accused of wrongdoing.
Opposition integrity spokesperson Fiona Simpson said in Queensland parliament on Wednesday that a whistleblower had claimed a long-term Labor staffer had been romantically involved with Mr Byrne.
Ms Boyd said there should be an investigation if the allegations were proven to be true.
She had earlier said Corrective Services Commissioner Paul Stewart had informed her on June 12 of allegations regarding Mr Byrne which had led to him being referred to the commission.
Ministerial diaries reportedly show Ms Boyd met Mr Byrne later that day.
Mr Byrne's resignation was accepted by Ms Boyd two days later, effective from July 4.
Ms Boyd was taken to task in question time on Wednesday over what she knew, with Opposition Leader David Crisafulli asking how Mr Byrne could resign instead of being stood down pending a commission investigation.
He said the timing of Mr Byrne's resignation entitled him to a state pension for life.
Ms Boyd later fronted media and indicated Mr Byrne's resignation was not in relation to the investigation.
She said Mr Byrne's resignation date had been brought forward from July 12 to ensure there was fresh leadership delivered to the parole board.
Ms Boyd told reporters she never asked Mr Byrne what allegations had been levelled at him.
"My view is the matter was referred to the appropriate avenue that was the proper course of action," she said.
Meanwhile, the Queensland government has appointed police union president Ian Leavers as cross-border commissioner after Victoria, NSW and SA adopted the roles.
The outgoing police union chief will manage issues for 12 local government areas that cover roughly 750,000 people alongside NSW, NT and SA borders.
The appointment, which is expected to help coordinate interstate police operations, was sparked by a youth crime surge in Goondiwindi, near the NSW border.
Police have deployed additional resources to the region with Mr Leavers expected in the rural town next week after starting in his new role on Monday.
Mr Leavers said he was approached by the government in the last 24 hours.
"Things have been unfolding, and I was given the opportunity, and I relish the opportunity," he said.
In other news, Premier Steven Miles will move a motion on Wednesday compelling all opposition members to produce a list of meetings they have had with registered lobbyists concerning their portfolios in this term of parliament.
Retrospective lobbyist meetings over the last three years also fall within the laws.
Previously, only the opposition leader and deputy opposition leader were required to publish such meetings.
Laws that provide greater protections for journalists in corruption watchdog proceedings also passed the parliament on Tuesday.
