回答您的問題：在加拿大和歐洲, 澳大利亞和美國都算長住過

我在加拿大和歐洲, 澳大利亞和美國都算長住過, 美國僅僅3個月. 當前在澳大利亞悉尼地區2.5年, 回答您的問題:

1. Very expensive, especially house and car, like in China.
2. Two tier: both public and private.
3. Expensive. Don’t have kid, so don’t know details.
4. Outgoing and friendly.  But racial tension high in some area; so are problems of Druggie, drunker and petty crime.
5. No idea, but I don’t plan live here for long, cus I hate  the weather, too extreme for me. Most of population live in coast area.  It is a fun-loving and lay-back country.
6. Very small market. But your degree is much precious here.
7. It is warm for most of a year. Ref to #5; if it’s rain, it pours; if it’s draught, it lasts over 10 years. You can find lots of books describe that.
8. Stress level, low; unless you start to drive. Drivers here are crazy; all act like on suicide mission.
9. No problem at all.

Summary:  It's a fun-loving and layback country.  If you like living in Asia, this is the place; it is much more like its Asian neighbours.
