I'm from Malaysia reside in middle east, no relation to Australia topic here.

In middle east you will have different people from around the world working here.

Generally, Whites are more sociable, asian if you don't say hello, they won't say hello to you. Arabs, if you say hello to them, they will say 10 times hello to you and if you don't say, you will say they are arrogant.

So the same concept applied everywhere in the world. you say people racist, arrogant. Other people also view the same on you.

Again, 1 or 2 people leave a bad experience for you does not means that billions of them is the same type. not fair to judge them in this way.
