The world's only single-country continent offers a reasonable cost of living, especially for health care; affable people speaking English, stable politics, low crime and a warm climate featuring lots of beaches. Australia actually encourage retirees, but they generally have to meet financial requirements, including a net worth, depending on location in the country, of at least $600,000 for a couple. Melbourne ranks high for culture and livability. Adelaide, on the south coast, and Brisbane, on the eastern, are also popular. Plane rides back to the States are direct, but very long--14 1/2 hours from Melbourne to Los Angeles.
