Senator XENOPHON (South Australia) (14:54): Mr President, I ask a supplementary question. Does the minister concede that whilst the government does not have the power to regulate private hospital charges, it does have the power to regulate disputes between private hospitals and health funds? Does the government consider that there is a discrepancy in terms of the 17 per cent figure quoted and that this does disadvantage South Australian private hospitals given what private hospitals have told me about the pressure that it is putting on them?
