Queensland's Liberal National government is under pressure after Labor asked the Crime and Corruption Commission (CCC) to investigate Olympics Minister Tim Mander and Families and Child Safety Minister Amanda Camm, who told Cabinet in July 2025 they were in a relationship that was only publicly revealed in May 2026.
Labor also wants Premier David Crisafulli and his chief of staff Richard Ferrett investigated for their roles in the matter.
''The Crisafulli LNP government is in the midst of a very serious integrity crisis,'' Opposition Leader Steven Miles told reporters on Wednesday.
"We've written to the Crime and Corruption Commission to ask them to investigate every element of this integrity crisis.''
A government spokesperson and the CCC didn't immediately reply to request for comment.
Labor's referral centres on when Mr Mander and Ms Camm told the government and the Integrity Commissioner about their relationship, and whether this happened early enough given the sensitive decisions they were involved in.
Labor says they may have been required to declare their affair earlier, including when they were sworn in as ministers, and claims the premier appeared to know about the relationship before it was formally put on the record.
The CCC is being asked to look at whether conflicts of interest were properly handled as key decisions were being made, including the move to shift sailing events for Brisbane's 2032 Olympics to the Whitsundays, the ''Games On!'' grants program, and other community funding tied to the ministers' electorates.
Labor's referral also points to a letter to the premier raising concerns about the relationship and its timing and the ministers' public claim they were ''on a break'' when they were sworn in.
Labor says it is not clear whether the Integrity Commissioner was given the full story when providing conflict-of-interest advice and drawing up management plans.
Under the Integrity Commissioner's guidelines, a close personal relationship within the previous 12 months can create a conflict-of-interest risk that must be declared and managed.
Mr Mander has repeatedly told parliament he met the Integrity Commissioner several times, followed all advice and made the right declarations at the right time.
''I made the declaration totally independent of any source, any instruction … any allegation or inference that I was influenced by anything or anyone is totally and utterly false,'' he said.
Ms Camm also insisted she did not lobby Mr Mander on Olympic venue locations, with the decision to move sailing to the Whitsundays made by Deputy Premier Jarrod Bleijie.
