Gee, it looks like you over-printed that Polish flag— you should get that checked out, /s.
I'm going to say, on record, that I could differentiate Austria from Australia prior to my teens, but I learned a year or so ago that Austrians speak a German dialect 😅. Not bad for a Western Hemispherean!
English making it more difficult than it needs to be. :P In Dutch it’s Oostenrijk (much more similar to the German word) and Australië, which are really easy to differentiate.
