Austria and Australia, 2 different countries in 2 different continents sound very similar in pronunciation. Well, Who cares? Everybody knows that.
Wait, not everybody, flight bookers definitely should CARE (attention needed)
Interestingly, There is a separate counter at Salzburg Airport for people who mistakenly flew to Austria instead of Australia, coz they really did n't care to read properly while booking tickets.
