We've been in Austria for two days and we still haven't seen a kangaroo." It's an old joke. While Austria is half a world away from Australia, many tend to confuse the two. Australia has cute koalas, Crocodile Dundee and crates of Fosters beer; in Austria, the snowcapped hills are alive with the "Sound of Music," Mozart's masterpieces and Wiener Schnitzels. But even former US President George W. Bush once mistook Australia for Austria, as he thanked former Australian Prime Minister John Howard for sending "Austrian troops" to Iraq. If you're visiting the country, you'll notice, particularly in Vienna, that slang terms abound. Here's a guide to help you fit in like a local on your next trip.
