The other issues you mention are just a distraction.
Fekk no- the biggie for me, as I mentioned, is Visas & all the bullshit that goes with it, and general bureaucratic hassles here. But that ain't to say I love the fact the beer is a fraction of the price too, and better- you can actually get Stout there without paying a kings ransom. Shit weed e'hh- dunno who had u mate, but I didn't find it so. Helps to know people I guess.
Tewwy, I live here (for 13 years) and you don't- you are a regular visitor, that's all. So I suppose you don't have to deal with this bullshit, and that's a perfectly fine way to go. Personally, I find myself resenting it more every year. The Byzantine, backward, corrupt, inefficient, entrenched Thai bureaucracy does my head in.
Now why don't you toddle off and listen to some armchair expert on Australia tell you all about the place. He obviously knows better than the residents.
Oh, I forgot to mention- you can own a business there, and actually work in it too, no hassles. Not that I personally would- but that's a biggie for several.
