Bogan means different things, but generally, it means someone who is not educated and holds ignorant beliefs, or who wears heavy metal band t-shirts, thongs and has a mullet
. Mostly (in my experience) it is used jokingly, though obviously it is an insult at its core.
There may be class distinctions elsewhere, but where I have lived, there has never ever been even the slightest notion of caring where someone comes from or lives, or how much they earn. Anyone who has a snobby or reverse-snobby attitude is shouted down swiftly.
The One Nation political party was often heard to be protesting the number of Asian people living here and taking over, but they were utterly ridiculed by the vast majority of people, and most were embarrassed that they ever even got a platform. Of course, some people supported the party, but it was a minority, absolutely.
Ilovesunflowers, it depends on what you think is racist. Here humour is used widely as a way of breaking down barriers, making things ok, etc and the terms used are inclusive in a funny way - that is, people take the mick out of everyone, and they are included in that. I have honestly not met anyone here with no sympathy, or with any hostility, towards Indigenous Australians, and Indigenous Australians I have met are as likely to make fun of white Australians in the same jokey way. White Australians are generally very ashamed and embarrassed by the past and have no ill feeling towards Aboriginal people, and want things to improve for them. There is a lot of focus on the culture in schools, universities and workplaces to ensure that people are aware and respectful. The Aboriginal culture, the language, and the understandable distrust many Aboriginal people in remote areas have for white Australians, as well as a genuine alcohol problem, has led to great problems in getting education, welfare, etc to where it is needed and it continues to be a very tough issue, but one that is being fought hard.
There was a Facebook group recently (with very few "likers") which had extremely offensive anti-Aboriginal content, and the outcry was deafening. I don't like that Australia has this reputation for being racist, because in my experience it really is not so.
