Queensland's Labor opposition has asked the Crime and Corruption Commission (CCC) to investigate whether Olympics Minister Tim Mander and Families and Child Safety Minister Amanda Camm properly declared and managed conflicts of interest arising from their relationship.
The state government ministers told Cabinet about their affair in July 2025, but only revealed it publicly in May 2026.
The referral has dragged in Queensland Premier David Crisafulli, his chief of staff Richard Ferrett, and raised questions about who knew what and when as the government pushed ahead with key decisions on Brisbane's 2032 Olympics.
The CCC has been asked to examine whether conflicts were properly handled, including shifting Olympic sailing events to the Whitsundays, rolling out its "Games On!" community grants program and approving funding tied to the ministers' electorates.
Opposition Leader Steven Miles said only the corruption watchdog could restore public confidence in the government.
"The Crisafulli LNP government is in the midst of a very serious integrity crisis," he told reporters.
"We've written to the Crime and Corruption Commission to ask them to investigate every element of this integrity crisis."
The LNP government has fired back by citing provisions in the Crime and Corruption Act stating that a person may commit an offence if they make a complaint that is not in good faith or is made recklessly or mischievously, signalling it believes Labor is playing politics with the CCC.
The referral notes Mr Mander and Ms Camm's private admission to Cabinet in mid‑2025, almost a year before the relationship became public, and a letter to the premier flagging concerns about the timing and completeness of their disclosures.
It also highlights the pair's claim they were "on a break" when sworn in as ministers, and questions whether that was enough to avoid declaring a close personal relationship under official integrity guidelines.
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.
The opposition said it was unclear whether the Integrity Commissioner was ever given the full story when asked to provide conflict-of-interest advice and draw up management plans for Mr Mander and Ms Camm.
The referral comes amid a wider integrity brawl in state parliament on Thursday, where question time was dominated by disputes over company declarations, ministerial conflicts and a finding that Mr Miles was in contempt of parliament.
Premier David Crisafulli seized on the contempt ruling, telling parliament it was "extraordinary" and a "historic and sad day in Queensland's political history".
The CCC declined to comment but will now assess Labor's complaint and decide whether to launch a formal investigation, which could hang over the government as it races to lock in venues, funding and planning for the 2032 Games.
