In Australia, I pay $190 per month (Australian dollars) for a health insurance for a couple of relatives ( 60 y.o.). My relatives are foreigners, i.e. they have no permanent residency and come on a tourist long term stay visas. On this plan they get 100% of everything that local Medicare would cover, with $500 deductible per year. Pre-existing conditions are not covered for 12 months, then they are covered. It is called "overseas visitors" insurance. My relatives had multiple stays for the full year each time.
Medicare covers 100% of hospital procedures and some doctor appointments (limit $500 per calendar year). Ambulance is covered too.
I think it is an excellent deal. Considering that Australian health care is good quality, the cost is dirt cheap.
