Medicare is a publicly-funded healthcare system in Australia for citizens and permanent residents that covers various medical services and treatments. Funded by taxes, it provides access to consultations with doctors, pathology tests, x-rays, and prescription medicines. Patients can choose their own doctors, with standardized fees, and access to free or low-cost treatment for some medical conditions, including chronic illnesses and mental health conditions. It is an essential part of the Australian healthcare system, but private health insurance may be necessary for some treatments and services.
