Senator SMITH (Western Australia) (14:26): My question is to the Minister for Finance representing the Minister for the Environment, Senator Cormann. I refer to figures released by the Clean Energy Regulator, which showed that the carbon tax has slugged Bluewaters Power with at least $60 million in increased costs in 2012-13. What broader impact is the carbon tax having on major employers in my state of Western Australia and on the broader economy?
