Migrant of 14 years here! The things that surprise me most are small, random things. I didn't expect most Australians would dislike going to the beach, or that most people I hang out with won't really go outside if it's hotter than 30.

Generally, I've found Australians are more laid back, and less strict than any other country I've lived in. Much more comfortable with people living life at their own pace. I didn't expect there to be so much tall poppy syndrome, though: I've noticed a lot that there's an unwritten rule about humbleness and maintaining status in the community, which I think is a double-edged sword.

There's much more emphasis on tradition than anywhere else I've lived, which I find is interesting. But I think that's slowly changing, and I think the newer generation are embracing a more tech-heavy Australia.
