If you want to go back to China in the future, you'd better go to UNSW. After all, UNSW is five-star. It seems that many people in China attach great importance to this and want to go to a prestigious school.
If you are an immigrant, UOW is also a good choice. UOW is really strong, and Australians will not think that UOC is worse than UNSW.
UTS is a practice-oriented school.
