Australia? No way that's overrun as the land is so big.
Sweden's a bummer though. It's the first place in the world that you think of when you hear blond hair, blue eyes. Abba etc.
Austria not Australia.
Australia is suffering a similar fate but with other peoples - mainly Asians but now it's Indians too as the government has already signed deals for more immigration(like Canada). I remember, when down under, hearing on the telly "Australia will grow in the coming years"... well, that was not an empty threat obviously. Australia was only around 20 million strong when I visited it - it could maybe house 100 million people but why should this paradise accommodate even more 3rd worlders than it already does?
Sweden has enough blondes still but there's a huge number of foreign peoples destroying it.
