When it comes to Australia, one of the first things you (should) will notice about Australians is their sense of humor. Overall, most Aussies like to have a bit of fun and stir people up a bit. If you are easily offended, then Australia might not be the place for you.
Poms, Kiwis, and other Non-Aussies
Australians are the first to make fun of everyone - including themselves. Thus, it only makes sense that they come up with nicknames for people from other countries (and for each other).
Here's a quick list of what you might be called when you get to Australia.
Kiwis - From New Zealand (For the record, New Zealanders call Australians ‘skips’)
Poms - From England
Yanks/Septics - From the US
Canucks - Canadian
There are many more here, but they might get you in a fight, so it’s better to learn them later than to remember them at the exact wrong time…
