My name is Alex and I have living in Sydney since I was a small boy(I am now 28 years old). I highly recommend not moving to Sydney. Although the traffic is bad in China, Sydney has one of the worst traffic volumes in the southern hemisphere. You will also experience a high cost of living.
What are the good points:
- Multicultural with quite a number of chinese and lebanese, but mainly in the rich areas like Chatswood
-People are quite friendly.
As you can see the bad points outweigh the goodpoints so you are better off staying there.
