Australianisms & Regional Slang

Having lived in Australia for a fair bit, I've come to notice that the language people speak here is... a little bit not-English. So I'm going to start recording some of the shit I hear, so that we can all marvel at this ridiculous dialect. What about you guys? What sorts of local words and phrases make tourists activate their face?

Anyway, let's get crackin', mate.

Entry 1: Good Egg

Good egg, descriptor. Used to describe someone who is pretty okay. "He didn't fuck me when he could've. He's a good egg."

This one's fairly straightforward: it's the converse of being a Bad Egg, i.e. someone won't take advantage of others' goodwill and is generally a good person.

Synonyms: alright bloke, decent fella (rare)
