Some people have rightly pointed out that Australia's treatment of indigenous people is awful. However, as was said up thread (I may be wrong, but perhaps this is what Cote was talking about), the entire society, culture and government is based on the British system. Everything that it has become is due to its British beginnings. It was colonised by Britain, its govt is the Westminster system, all of its views were established by British settlers (both convicts and free settlers) and it still has the Queen as Head of State. Australia was settled in 1788 and became independent in 1901, only 112 years ago. I bet some UK shops have cheese for sale that's older than that!
Australia is incredibly insular - it's due to a thing called the tyranny of distance. Australia has never been forced to reach out the way that the countries of the EU were. It has never experienced wave after wave of invasion over millenia and it has never experienced the horror of war, EVER.
Instead it has been left alone to simmer in its isolation and security. Throughout its very short history, it has been incredibly isolated from the rest of the world. International travel is a modern invention, it tooks weeks by boat, so people who went there stayed. They developed ideas and those ideas were perpetuated by subsequent generations.
Ever hear of the "Ten Pound Poms"? They were British settlers (lots of Italian and Greek people went at the same time) who were assisted by the govt to relocate to Australia after World War Two.
Yes, there was the White Australia Policy. People with predominantly British/European ancestry wanting newcomers to be similar to them. Don't forget that this was the era of Communism... reds under the beds and all that. They were suspicious of other cultures and simply going on what they knew. Can you blame them?
The Australian Prime Minister was born in Wales. That's the Wales you'll find on the map to the left of England.
Australian society is evolving and catching up to the rest of the world. Just slowly.
