Australia is basically the UK transplanted (mostly) into the (mostly dry) tropical climate zone.
I've reads somewhere that there is a bilateral agreement between Finland and Australia granting each other's citizens or legal residents a right to public healtcare under the same conditions as the locals. Is this true?
I think so. About 20-30 years ago it was possible for an English citizen to claim both English and Australian social benefits. It meant a high rate of unemployment in those communities as there was no need to get jobs. Those suburbs are often 'low income' places still.
I met an Australian-Finnish couple on a train some years ago. The guy was a Finn who had emigrated to Australia 40 years ago. His wife was Australian. They told me that (some) civil servants get a six month paid holiday every five years or so. This is a legacy of the colonial period when traveling to Australia was like interplanetary travel. It was, however, the first time in 40 years the husband visited his country of origin. He was so uncomfortable speaking Finnish that he and I continued our conversation in English after his wife left the restaurant car.
