i'd like to address this apparent issue of racism in australia.
having lived all my life outside the so called "big three" cities of Melbourne, Sydney and Brisbane, I can guarantee racism is NOT prevalent throughout the rest of the country and is no worse here than the UK or the USA, or other first world countries.
in the past few years there have been some highly publicised incidents of apparent race-based bashings of international students, however it was widely accepted these had NOTHING to do with race, but were opportunistic attacks on staff at late night convenience stores and petrol stations, who are regularly staffed by international students due to their study requirements. these attacks were well documented in Pakistan and India as race-based attacks, but it was later shown here in Australia race had nothing to do with it, yet THIS was never reported (from what I've read/found) in Pakistan and India. as a result, Australia has been branded a dangerous country by these other countries, which is quite shocking when you consider how dangerous Pakistan and northern India can be themselves.
There HAS been a long history of abuse of Aboriginal people in Australia, however this is no worse than the way native Americans and the Maori people of New Zealand have been treated by the colonialists in those countries. In reality, the colonial-based racism here is no worse than in every other colony; yes it's bad, but no worse than many many other countries. I'm not saying it doesn't exist, as I know too well that it does, and I see it on a daily basis. That being said, it's not a one-way street, with some of THE most racist people I've dealt with being Aboriginal people themselves (not all, of course).
There are many other facets of racism I haven't covered, mainly as I'm not a specialist in this area and can only speak from my own experience, but comparing my life here in Australia with the extensive travels I've done throughout South East Asia, the UK and north America, it's no worse here than anywhere else.
