Yes, there are bigots in Australia - the same as anywhere else, really. But remarkably little (any ?)organized race-related violence of the type you ask about. Nothing along the lines of say, the riots in Brixton a few years ago.
In fact, Australia has a pretty good history of tolerance, when you consider the diversity & the number of people from different cultures who have successfully settled here. (Including my own family.) It is very much a cultural melting pot.
Racial concerns at the moment include debate about Middle Eastern people of Muslim faith wishing to be accepted as asylum seekers (or "illegal immigrants", depending on which side of the fence you sit on.) The detention centres are a major cause of debate, concern & division in the wider community. No doubt November 11, the Bali bombings & our government's support of a possible war with Iraq has contributed to the divisions. (Now we have government advertisements in the media encouraging people to 'dob in' possible "terrorists" behaving suspiciously!)... There is a lot of fear out there, but thankfully no organized violence as an expression of this.
And of course, Australia's history of mistreatment of the Aboriginal people of this country is truly shameful ... Yet we have a prime minister who refuses to officially apologise on behalf of the nation, despite most people wanting this.
So yes, there are racial tensions, but virtually no organized violence as an expression of it. And there is a great deal of interest & debate in the media about these issues.
In response to your second question: I don't know if Australians are hard for others to understand. I can't see why we should be. We do speak English!
