I'm going to Sydney, too, but I want to immigrate. I especially like Australia.
It costs 300,000 yuan a year to go to Britain, but if you have a scholarship and tuition reduction, British graduate students can complete their studies in one year. Why not?
Sydney costs about 200,000 a year, with tuition 1.6 million and living expenses of about 600 Australian dollars a month. (Friends experience it personally)
Personally, I suggest you go to England. Many people who go to Australia think Britain is too expensive or just want to immigrate. Many people want to go to England, but they can't.
No matter what you finally decide, good luck! ~~~
