Yes there are aussies that are racists but they are not the majority. There are heaps of Aussies who are really nice people and are very open to Asians.
Let me share with you my experiences when I was a student in Melbourne in 1998.
On my first night in Melbourne, a car pulled up along side me and 3 white aussies spew vulgarities at me and in short ask me "chink come s*** his d*** and to f*** back to where youI come from" and this was my 2nd hour in Australia having just landed and taking a walk after checking into the hotel.
When registering for courses in school, I had an admin staff who refused to help me and basically told me off in my face. "Im not helping you!" but was all smiles to fellow white aussies.
My housemate came home in tears, cause a guy pushed his way in front of her while she was queing for Subway and told her "F*** u Chink....."
When looking for a house, some landlords when they knew the people asking were non white aussies, they immediately informed the agent to reject us.
However having said all of the above. I have also encountered the following.
My head of department, a veteran professor apologizing to us in public for the racist acts against us.
Aussies that you dont know at all, going out of their way to help you out when u are lost.
Aussie friends who endured getting racist taunts from other aussies for being "losers" as they are hanging out with "chinks" and still remain your good friends.
Aussies that I become so close to that we are like brothers and will do anything for each other.
What Im trying to say is that there is racism of course. There is in every country even here... look at the way we treat foreign workers as untouchables that we have residents forming watchgroups to make sure foreign workers don't sit under their void decks. However that that doesn't make us all racists does it? Same for Australia, yes you have your racism here and there and someone like Pauline Hanson. However same time you will find lots of nice people who are genuine and friendly. And yes of course... most of them always wonder "do you know gong fu??"
