回答您的问题：在加拿大和欧洲, 澳大利亚和美国都算长住过

我在加拿大和欧洲, 澳大利亚和美国都算长住过, 美国仅仅3个月. 当前在澳大利亚悉尼地区2.5年, 回答您的问题:

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.
