I'm not sure I understand. The Australian system is weird that it isn't a insurance based system (like e.g. Germany), but they give tax insentives to high earners to get insurance. However those insurances don't pay for the basic stuff paid by the medicare system, but for extra things, for example you get faster treatment for elective surgery.
