Hi Tod. It seems if I go this route my 84 yr old Mum has to do visa runs. Given that we would likely do the retirement extension within the first 90 days. So is that still the best route?
Given the amounts you are talking about to cover the retirement visa and living costs it may be worth considering opening a Foreign Deposit Account to sit alongside your standard account. This would then allow you to benefit from exchange rate increases (if they happen) in the future.
