Senator PATRICK (South Australia) (14:34): Following on from your answer, Minister, there are numerous Murray-Darling inquiries running at the moment—in New South Wales, an ICAC investigation, an ombudsman review and the Matthews review; in Queensland, the metering review; now in South Australia, a royal commission; a Senate inquiry; a Murray-Darling Basin Authority review; and an Auditor-General review. This all seems very inefficient. Does the Commonwealth government concede that this could all have been avoided had a federal royal commission been established?
