My wife and I (both 66) have two daughters, both of whom are now citizens in Australia. We are living with one daughter in Melbourne and applied for contributory aged parent visas (864) a few months ago. We are quite confident we will be granted these visas, but due to the collapse of the pound, we will struggle to find the $90k to pay for them. We are not sure if we could swap to non-contributory aged parent (804), but if we could, can anyone advise what would be the disadvantages?
