Ive never heard that J Bone, ive usually associated that saying with Americans.

I would have to agree with boxbeach in general. Basically every English country has their own terms for everday words. It was only a few years ago I came across the term "Chillybin" from Kiwis, and that's their word for what we Aussies call an "esky". So what? You have a laugh, share a beer and move on. All kinds of English speaking tourists come to Australia, and the influx increases whenever there is a sporting event on like the cricket, Super 14 rugby etc. We get heaps of South Africans and Poms here (there I go again, slang for the English, sorry guys) and all the different types of slang words come out. Its just in our make up, who we are. Nobody is forcing you to use those words. I never say Chillybin, but on rare occasions have said Cheers, which happens to come from England. So what?
I think its a bit much to have a whinge because some people are using slang words from another country. Like I said, its their choice if they hear it and want to use it. As for Garbo, Milko, Postie and Truckie its just our way of shortening the word or modifying it so it rhymes with other words. I'm sure the Kiwis and English would have different words, and I'd be intrested to hear what they are.
If in the end we all share a beer after taking the piss out of each other, then its just a way for us to accept and learn interesting and different things from each other. If you feel threatened by tourists and the way they speak, then your not very accepting are you?
As for the whips and chains that were mentioned before, I didn't realise Canadians girls were so kinky! hehe Can't wait to get there!
What a lot of gallahs here.
Look up a Strine dictionary online. There's some really interesting expressions from down unda.

I started calling my son "The Sprog" several years ago. His friends just always look confused, he simply smiles.

Now that's a blast from the past. I think I still have a copy of "Let's Talk Strine" somewhere.

It's this book from the 60s that includes such gems as:
Letty Mare Fit: Let him have it. As in: `Letty mare fit tiffy wonsit. Zarf trawly zonier kid.'
partial text from the book

I think one that might be a little more unique to adelaide is "heaps good", for example "south australia is heaps good" :)
At the mitsubishi plant in adelaide they have big signs up all around the plant that say "when we say no worries, it's not a saying its a promise" in reference to their quality.
