Police once apprehended a man at a train station in Kyjov (Kiyov), Czech Republic. He was reported to be drunk but they only found him terribly confused. Turns out, he was a Ukrainian trying to return to Kyjev (Kyiv) but a cashier in another town misunderstood and showed him the wrong train.
At least that's the same continent and not literally on the other side of the world.
He only had a 150km detour. You can’t blame him for thinking “Kyjov” is the Czech spelling of “Київ” as he might not even have known the alphabet.
The whole thing is an advertisement on a baggage carousel in Austria for a company called Commend that offers intercom systems.
Salzburg airport's website has no mention of a special desk for those trying to reach Australia. If there were 100 errors per year, that would be 1 every 3 days, providing limited need for a desk.
