Is there a reciprocal healthcare with Australia?

Yes, there is reciprocal healthcare with Australia via Reciprocal Health Care Agreement RHCA that Australia has with 11 countries, allowing visitors from those countries to access limited Medicare benefits for medically necessary treatment while in Australia. The 11 countries are United Kingdom, New Zealand, Republic of Ireland, Sweden, Netherlands, Finland, Norway, Belgium, Malta, Slovenia and Italy. Under RHCA, if you are a citizen or permanent resident of one of those countries and you are visiting Australia, you can enrol in Medicare at Services Australia with passport, visa and proof of residency from home country, and you can then access public hospital treatment as a public patient for free, GP treatment for medically necessary conditions, and subsidised prescriptions under PBS, similar to Australians. However, RHCA does not cover private hospitals, ambulance, which costs $1,000 to $1,500, dental, optical, physiotherapy, or medical repatriation, and it only covers medically necessary treatment, not pre-existing or elective treatment. For example, UK tourists can get emergency treatment for free in public hospitals under RHCA, but need private insurance for ambulance and private care. RHCA is not the same as European Health Insurance Card, it is separate bilateral agreement. If you are from USA, Canada, Germany, France, India, China, there is no RHCA, so you must have Overseas Visitor Health Cover or travel insurance and pay full cost. So yes, reciprocal healthcare exists with 11 countries, but it is limited.
