If I'm earning $180000+ I'm not complaining ;-)Been posted before, but contains some updated info. In short, death and taxes are unavoidable.
So if you are a top earner and already taxed at 45% in Aus, then SARS can't claim expat tax from you.
Also interesting is the Medicare levy surcharge if you earn above a certain amount and don't have a private medical fund. So many little gotchas when looking at moving overseas.
* Seems like the surcharge will cost you at least $75 a month (if you earn over $90 000 a year), in which case you might as well get a basic hospital plan which costs about the same from what I've seen online.
