The biggest fraud investigation in Papua New Guinea (PNG) led to the uncovering of the misappropriation of approximately US$75 million from a trust fund linked to the Ok Tedi mine, a controversial mine accused of causing severe environmental damage to its surrounding community over the last few decades. The mine led to one of the worst environmental disasters, with around two billion tons of untreated mining waste being discharged from the mine. The fraud investigation discovered a money laundering and misappropriation scheme, finding that funds intended to go to the PNG's Western Province were instead improperly paid to the OK Tedi Fly River Development Foundation and their Australian law firm. A prominent Australian lawyer was arrested on multiple charges relating to the misappropriation of the funds.
