While the level of health care is generally not high, there are some excellent private medical clinics. The standard of health amongst expatriates is generally reasonably good. The most common experienced minor illnesses are gastro-enteritis and a variety of viral infections.
The hospital service is limited and most expatriates requiring emergency surgery or specialist treatment have this done in Australia. Your health insurance would probably cover the cost of this including, where necessary, the cost of any emergency evacuations.
There are some very good dentists here with but some expatriates prefer to leave their dental work until they are on leave.
