People of Australia, can you give me a food that is common in your country?

A fellow teacher and I do a culture club with our students after school and we like to bring in food from the place we are studying about. The next place we are studying about is Australia and I personally don't know what food you guys consider Australian. I'd also like to know a food maybe that the Aboriginal people tend to eat as well. Nothing too extreme like Kangaroo or something. I can't get that in the United States. LOL.
