I actually dont agree completely. I mean yeah, alot of malaysians love to migrate overseas for the sake of better education, better like - thus obtaining PRs/citizenship overseas.
I dont know, but for me, I cant think that far, for my so-called "kids" and "family". Right now, after spending four years in Melbourne, I still cant feel at home and at peace at this place. I cant blend completely into the culture. What I see is that international students stick with each other, and local students look at intl students differently.
Basically what i am saying is that, unless one has been raised in a country for most of their life, it is very hard to really mix in and feel at home. For alot of PRs/intl students, they dont care if they can mix in with the locals anyway. They feel contented to just keep their social circles limited to intl students.

and besides, I dont think Australian primary/secondary educaton is all that great.
