It’s been nearly five months since investigative journalist Nick McKenzie broke one of the biggest stories of the year, and exposed what he calls “an unholy alliance” between gangland figures, and one of the most powerful labour unions in the country.

He revealed that the CFMEU had become a fiefdom in which bikies and former stand-over men, among others, were given positions of power on building sites - many of them government-funded projects. The culture they created was toxic. Right up the east coast of Australia, the threat of violence was real and omnipresent.

Today, Nick McKenzie, on the battle for control of the construction industry, which will be the focus of a court hearing next week. And whether the people in power, who allegedly turned a blind eye to the alliance, will ever be held to account.
