Geoffrey Watson SC appeared before the Queensland Commission of Inquiry into the CFMEU for the third and final time on 31 July 2026. He used the occasion to push back against the Allan government's public attacks on his corruption report and to clarify a key claim linking Melbourne underworld figure Mick Gatto to companies that received favourable treatment on Victorian government projects (The Guardian, 31 July 2026).

Watson's report, formally titled Rotting from the Top: The CFMEU in Victoria During the Setka Era, was commissioned by a former administrator of the CFMEU (the Construction, Forestry, Mining and Energy Union). It estimated that CFMEU-related corruption cost taxpayers at least $15 billion. A redacted version is publicly available as Exhibit GW-13 on the Queensland inquiry's website. The report was submitted to the Queensland inquiry on 11 February 2026, discussed in the Australian Senate on 3 March 2026, and examined before the Senate Select Committee on Productivity on 29 July 2026 (Queensland CFMEU Inquiry transcript, 11 Feb 2026; Australian Senate Hansard, 3 March 2026).

The report found that Victoria's $100 billion Big Build infrastructure program hosted and enabled systemic corruption, sexual exploitation, and drug trafficking (ABC News, 29 July 2026). Among its central allegations: that Mick Gatto controls M Group companies, which received favourable treatment from the CFMEU on Big Build projects, and that company directors Michael Portia and Tony Paragalli acted as "dummy directors" on Gatto's behalf. Gatto, Paragalli, and Portia have previously denied the allegation.

On 31 July, Watson acknowledged a nuance in his Gatto claim. He told the inquiry he "probably shouldn't have said Mick Gatto owned them" and accepted that Paragalli and Portia also likely own part of the M Group companies. He stood by his central allegation that Gatto "controls" them (The Guardian, 31 July 2026).

The Victorian government's response to the report was hostile. Attorney General Sonya Kilkenny described it as "unfounded." Police minister Anthony Carbines called it "florid ramblings." Watson told the Queensland inquiry that the Victorian government was effectively suggesting he "made it up" (Brisbane Times, 31 July 2026). He described the Allan government's attacks as "awful" (Herald Sun, 31 July 2026). Watson also threatened to walk out of the Queensland inquiry (Hunter Valley News, 31 July 2026).

The political consequences were swift. Jacinta Allan stepped down as Victorian premier in the week of 27 July 2026 after losing the support of the Labor caucus (the parliamentary party room whose backing a leader needs to stay in power). Her loss of caucus support was due in part to her failure to act on the CFMEU corruption scandal. Ben Carroll succeeded Allan and on 28 July 2026 committed, as his first act, to a royal commission into the construction industry (The Guardian, 31 July 2026).

Watson noted on 31 July that no one from the Victorian Labor government had contacted him about his report. The Victorian Parliament's notice paper has formally referenced the report and noted its submission to the Queensland inquiry (Victorian Parliament notice paper).

The broader context here is about the difference between a commissioned report and a royal commission. Carroll's commitment to a royal commission is a sharp reversal from the Allan government's dismissal of Watson's findings. A royal commission carries compulsion powers that a privately commissioned report, however thoroughly researched, does not. Think of it as the difference between an independent audit that can flag problems and a formal judicial inquiry that can force witnesses to testify under oath, seize documents, and refer criminal conduct to prosecutors. Watson's report could name patterns and allege control structures; a royal commission can legally compel the evidence to back or overturn those claims.

There is also a notable contrast between Watson's approach and the government's. His willingness to retract the specific claim of ownership while maintaining the broader allegation of control is a careful, calibrated correction. The Allan government's framing of the entire report as "unfounded" or "florid ramblings" left little room for that kind of nuance, and the caucus revolt that removed Allan suggests that strategy was politically unsustainable.

The Queensland inquiry, meanwhile, has served as the primary forum in which the report has been tested under examination. Watson's three appearances, culminating on 31 July, gave the report a procedural legitimacy that competing state-level responses could not match. The Senate's engagement with the report on two separate occasions, including before the Select Committee on Productivity on 29 July, indicates the findings have gained traction at the federal level as well, potentially pressuring jurisdictions beyond Victoria.

Looking ahead, the trajectory for stakeholders in construction, union governance, and integrity frameworks now hinges on the Carroll government's royal commission. What that inquiry's terms of reference will cover, and whether it will examine the CFMEU's interactions with state government procurement processes, will determine whether Watson's $15 billion cost estimate and his allegations regarding the Big Build program receive the judicial scrutiny Victoria's political leadership has so far denied them.
