Hey whiteshields1830,
I know it's pretty tough but no need to be nervous now as you did your part already (the things you can control). Unfor with time, the waiting gets worse but just hang in there.
I doubt being Australian or Chinese would increase your chances, I believe it's the other way around, might be wrong tho.
I am curious as to where you are getting these figures, 470+ and 11/12 Australians accepted? gmatclub, insead stats,... not sure on average how many Australians Insead tends to accept each intake.
