Since being re-established in December 2016, the ABCC has recovered $598,067 in wages and entitlements for 579 employees in Queensland. The majority of these recoveries followed proactive audits, with many of the workers unaware they had been underpaid. But Ms Grace hit back, saying the facts spoke for themselves. The Member for Kawana should acquaint himself with them, she said. And as revealed in Senate Estimates a year ago, the ABCC had spent $3.2 million of taxpayer funds over three years in prosecuting unions, union officials and workers but not prosecuted a single employer for sham contracting - a commonly-used tool for wage theft and worker exploitation.
