Which conclusion?
That property is "over valued"? You said yourself the average Singaporean is not able to buy the property I linked to.
That most Singaporeans live in public housing? It says so in the article you linked to.
Now THAT is interesting.
So YM, given that property is massively over-valued in SG, and the majority of people live in public housing .. do you not see that as a possible "destination" in Australia's future?
two links for you.
