It is not so much the "migrants" but the ones who buy who are not residents or migrants.
By injecting huge amounts of money into a market they are in fact manipulating the market and the system to the detriment of the "locals"
As easy answer to it would be if buyers were compelled to include their tax file number on the purchase contract this would overcome the inability or reluctance to enforce the FIRB rules.
If they do not include the tax file number they pay 50% stamp duty
It is the same story with much that the government doesn't do, and that is they don't enforce the laws that they have enacted, they just sit on their hands.
We do need foreign investment but it must be working investment not static and it must involve locals in the mix which is what the majority of countries overseas do.
Try and buy property in the Philippines without a local partner and see how far you get
