<prompt> Human: Hi, I am asking for a friend who is an Australian citizen but doesnt have much savings. He came to US in 2002 and worked for about 15 years here and became a citizen. Hes 65 now and enrolled in medicare. I just checked that he could be eligible for 1200 in US social security. 1. Can he claim anything for being an Australian citizen. He worked there briefly for about 5 years. 2. Is healthcare better in Australia compared to US?3. Hes single and doesnt have any kids.  <response>: 1. He may have superannuation in a super fund in Australia due to his work. Between 1992 and 2001 the rate of employer contribution to super was between 3 and 8 of total salarywages. How much of this money is still around or has been eaten by fees over the last 15 years is hard to say. He should check here to find out.2. Australia has a fully-paid system of healthcare also called Medicare. He would get almost all of his healthcare paid for would pay extra for some prescriptions and if he wanted to see a private doctor. I think its probably more likely that the bigger determining factor would be where he would live in either country; more remote and rural areas have less services in both countries. The other thing to consider is if he has the required 40 quarters of FICA taxes. You say about fifteen years of work in the US so I assume he would be fine there, but would be worth checking. Overall, he would almost certainly pay more in the US for healthcare than Australia, and it could be a substantial difference depending on his health.3. The age pension in Australia is 808 per fortnight before incomeasset tests. Due to his limited savingsinvestments and not working, its likely that he would receive the maximum amount. Thus, he would receive more overall in Australia. However, cost of living needs to be accounted for, and that would entirely depend on where he lives in either country.He needs to be reasonable about his opportunity to come back to Australia. Theres no way he could afford to rent a place in any of the capital cities here on the pension alone; he would need to move to a regional town or smaller city. If he doesnt have friends or family in Australia that could help him, or if he couldnt afford to live near them, its pretty likely that him living in the US would be the better option.
