I am a year one medical student in USyd, and I am from Hong Kong. There are two students from Hong Kong, one from mainland China and eight from Singapore in my year. You can refer to the university's website for the statistic.

I cannot get any loan from any local banks and Hong Kong Government, though I really hope I can. I personally know all of the Singaporean international students, and none of them can get any loan from any Singaporean banks or government. I have not known the Chinese student yet, but as far as I know, there is no loan from the PRC banks or government for students studying overseas. Hope it helps.
