Lots of Australians are moving to Thailand or Indonesia to escape our high cost of living. Are these countries headed into a situation similar to Portugal, which also had a trend of people moving there from countries with a higher cost of living?

Anecdotally, I see lots of Australian Redditors and social media personalities announce plans to move to leave Australia to escape our high cost of living and housing crises (either that or they announce why they already left). Countries often considered are Thailand and Indonesia.

I feel like I've seen this happen before, namely the case of Portugal. Lots of people moved to Portugal from countries with a higher cost of living and housing crises. And now the big irony is that all these people moving to Portugal for lower cost of living and to escape a housing crisis gave Portugal a housing crisis of its own.

Will the outflow of Australians escaping our high cost of living and housing crisis lead to Thailand and Indonesia ending up in the same situation as Portugal? Or are there reasons to believe that Thailand and Indonesia will be able to handle this issue better than Portugal did?
