Leaks show contractors paid Mick Gatto, one known gangland figure, to obtain access to sites in Victoria's Big Build. Companies listed Gatto on payroll. Payments were meant to smooth entry and avoid delays.
Former watchdogs have called for one royal commission into the scandal. Further leaks indicate the government ignored earlier warnings about violent contractors linked to the CFMEU. The revelations tie underworld influence to large infrastructure work and raise concerns about oversight. The leaks were published on 28 June 2026 by several Australian outlets, such as The Age and SMH.com.au. The information came from internal documents and emails.
