Victorian businessman Jake Calvert was charged on Tuesday by Victoria Police’s Taskforce Hawk with 232 counts of making a false document, following an investigation into an alleged scheme that distributed hundreds of fake qualification certificates on major state infrastructure sites.
The charges come a week after reports revealed that NSW conman Jack Younes, who uses several aliases, had been distributing hundreds or even thousands of fake building qualification certificates to Victorian construction firms and workers for at least three years, including those working on the Big Build.
According to the reports, federal regulator the Australian Skills Quality Authority was tipped off about Younes’ operation in 2023, and state regulator WorkSafe Victoria received a further warning in July 2025, yet the scheme allegedly continued.
The police breakthrough has prompted Victoria’s state opposition to commit to expanding the terms of reference of the Carroll government’s royal commission into the building industry, if it wins government, to examine the qualifications scandal and how it may have operated for years without detection by WorkSafe or other agencies.
