Medicare is the publicly-funded universal health care insurance scheme in Australia, operated by Services Australia. Medicare is the main way Australian citizens and permanent residents access health care in Australia, either partially or fully covering the cost of most primary health care services in the public and private health care system. International visitors from 11 countries have subsidised access to medically necessary treatment under reciprocal agreements. All Australian citizens and permanent residents have access to fully covered health care in public hospitals and clinics.
