Racism and Australia

Racism is a touchy topic, and rare is the country that has no issues with racism at all.
Australia and racism in Australia has recently hit the headlines in India, following the series of attacks on Indian students studying there.
Some of the attacks might be copy cat types and others might be opportunistic preying on a vulnerable section. But the undercurrent of racism in all this has been dismissed by the Australian police. This I find appalling. Its almost as if they are saying "What? Racist and us? You must be joking".
Well if you don't believe those Indian students were attacked because of the color of their skin or their accents, maybe we should check in with the Aborigine's about the Australian attitudes towards racism. Maybe Muralitharan the Sri Lankan spinner who has been given a horrendous time in Australia each time he plays there can testify.
My aim is not to malign all of Australia, but when racial prejudice results in Physical violence , it is probably time to examine attitudes to racism within the country.
