Abbreviate everything!
Australians love to shorten all the words that are possible, so don’t be shocked when you will talk to someone and you won’t understand in the first place. You will get used to the Ozzie slang (if not, just smile and nod). There is actually a good step-by-step guide on how to master the Australian accent even on WikiHow
Yeah nah meaning
From the first minute you spend in Australia, you will become a “mate” for everyone, and “no worries” will be your most used phrase here, so “No worries, mate!” you will learn along the way. Yeah, nah! is a just common phrase you will hear a lot. It basically means: “I see your argument, but, just no”.
One tip:
Just shorten everything, blend your words together as much as possible and that’s basically the Australian Accent.
