Two of Australia’s most prominent trade union figures, ex-CFMEU boss John Setka and the Victorian head of the Health Services Union, Diana Asmar, are facing a multi-agency investigation into allegations that more than $3 million of union money was paid to printing firms for non-existent or “ghost” services.

Ms Asmar, a one-time Labor Party powerbroker who has sought credit for exposing corrupt former health union head Kathy Jackson, is now also separately facing questions over almost $200,000 of members’ funds she allegedly spent on work expenses, including Gold Class movie tickets, alcohol, meals and items from IKEA.
