Well thanks a lot.
But I've just found out that you have to own a permanent visa to be allowed to buy a property in Australia.
That's "funny" that I live in a country where foreigners have plenty of freedom but at the same time, the countries they come from don't play with the same rules.
I guess I have to limit my search to European countries which might not be as protectionist as the ones from the rest of the world.
Sorry to sound bitter but well ... I'm bitter now
