First to get a Australian pension you have to be a Australian citizen,second you have to have lived in Australia full time for two years before you can get a pension,third there is no widows pension in Australia.🇦🇺
Depends on what you call large amounts, hope you are going to do something with the money,don’t leave large amounts in the bank as interest rates are very low and the baht is over priced and most people think it will fall next year and the other thing is the new Thai taxes that have come in.
