Australian slang

I spent the last few days watching videos about the Australian slang, it's very interesting all the words that change in the Australian slang, I'm accustomed to the American english but now I have this issue I need to learn which words are said different in Australia.
And the other issue is the Australian accent, I've been listening to Australian radio and it's difficult to understand everything they say. Their accent is complicated. I'll try to get used to it.
That's all. Something funny the Australian people name the toilet is a dunny hahaha
