My question is to the Minister representing the Treasurer, Senator Gallagher. Industry stakeholders estimate that cost blowouts linked to the CFMEU conduct on construction sites can be as much as 30 per cent. The CFMEU's involvement on Victoria's Big Build has been conservatively estimated as costing the Victoria taxpayer $15 billion. Minister, with billions of Commonwealth taxpayer dollars being allocated for infrastructure projects right across Australia, has the government quantified the cost impact of CFMEU driven practices on federally funded infrastructure projects?
