A joint federal and Victorian police taskforce has been established to crack down on widespread union corruption, violence and organised crime connections inside the construction industry.
Prime Minister Tony Abbott and Liberal Premier Denis Napthine announced the taskforce on Friday morning in Melbourne.
Mr Abbott said it would "firmly, decisively and swiftly" deal with widespread corruption in the building sector.
The move has been prompted by evidence given to the Royal Commission into trade union corruption.
Victorian Police intelligence indicates trade union officials were directly involved in criminal activity, along with organised crime figures working on behalf of unions.
