Honestly I suspect, that you as many others are trying to find a spot in a western country and it might have been that you have realized, that for whatever reason Australia will not be as easy to immigrate as you thought anymore.
I'd like you to know that I'm in Sydney to study and not to live here permanently. My options to stay in Australia is not too hard if I decide I want to later on.
The reason I'm looking to go back to Canada is because I was removed as a minor at a very young age and most of my extended family resides there as citizens. Not sure what you're on about but I'm not someone "trying to find a spot in a western country."
