National Customs

[Albertosaurus Rex]

Well, I am not very familiar with Australia so I'm not sure how local customs differ from Dutch ones. But concerning clothing: as Australia is basically a "Western country" (despite its actual location), I wouldn't worry too much about your clothing.

I go to college in Amsterdam, which sees a lot of tourists. I don't recognize them by clothes but by the large backpacks they sometimes have with them. People are often warned to beware of pickpockets in Amsterdam, but on four years I have never had anything stolen. Your be on your guard and you should be fine.

Of course, I don't know if you will be coming anywhere near the Netherlands so I don't know if this will be of any use to you. I don't travel much myself.
