They are all big cities. Both are fine. The University of Sydney is located in the city center. The railway station has convenient transportation and there are many Chinese communities nearby. Life is the most convenient among the three universities. It takes only 10 minutes to get to CBD by train. Xinnan is in the East District, which is a high-end area for foreigners. There are also many Chinese shops, and the transportation is ok, but there are only buses, and there is no subway. It takes more than 20 minutes to get to the city center by bus. We must wait for the plane. I hate going to class and waiting for the bus after moving, and I'm always late. Melbourne has been there once. On the whole, it is not as prosperous as Sydney, but it is a particularly ecological place. The whole city is like a garden. House prices have gone up really fast recently. The one next to the University of Sydney is the most expensive, and Xinnan is a rich area, which is expensive. Melbourne is certainly not as expensive as Sydney. But it is also rising rapidly. I don't know it in detail, so I can't talk nonsense. Basically, these are not problems. If you can drive, there will be no problem. Typing by hand, using.
