Lives would be put at risk by "radical" National Commission of Audit reforms to Australia's health system that would begin an Americanisation of Australia's health system, furious doctors say.

They have warned the Abbott government not to go ahead with proposals such as compulsory fees for visiting the doctor, which they say would lead to a massive worsening of the burden of chronic disease in Australia.

They have described other proposals, such as asking busy hospital emergency departments to charge fees, as "fantasies" that could not possibly work.

Australian Medical Association president Steve Hambleton said the recommendations were designed by "bean counters" with no idea of how the health system works.
