I don't think anyone is disagreeing that ATC in AUS can be terrible also. ADL, more than one plane in the sky and things can slow down.
What has it got to do with the shocking HKG ATC? Because some other places have issues it is OK to have incompetence in HKG? It is OK to have very inexperienced controllers in a very busy part of the world loosing the plot when there are some clouds?
Your argument seems to be based on race, white guys in AUS are bad so stop complaining about the asians in HKG? Is that it? Some people are missing the point.
