Finally found the old discussion I dimly recalled. In honor of peta and her particular interest in slang, I'm reviving something we talked about over four years ago (original here). The post starting the thread read thus:

arvo: afternoon
bikkie: biscuit
blower: telephone
blue: a fight or argument
bonzer: great
boobley: a big fight/argument
bugger-all: very little
go to buggery: go to hell!
carked it: died (e.g. the car carked it half way to the beach)
chockie: chocolate
chook: chicken
crack: a mental express extreme anger or rage
daks, underdaks: pants, underpants
deadshit: a person of low intelligence (an insult)
divvy van: police van, paddy wagon
drongo: a really dumb dude
up the duff: pregnant
dunny: toilet
fag: cigarette
fair dinkum, dinkum, dinky-dye: honest, truthful, honourable
fart-arse: screw off, waste time
crack a fat: get a boner
footy: a football, or a game of football
franger: condom
goes like a shower of shit: really fast or impressive
hooroo: goodbye, see you later
no wucker’s: a polite shortened form of the spoonerism ‘no wucking furries’
norks: breasts
piss: alcoholic beverage
pissed: drunk
root: synonymous with the word f*ck
sook: a ‘cry-baby’
wanker: one who masturbates... A good all purpose insult.
wowser: prude
yobbo: a rude or ingnorant person

Half a dozen of those words or phrases, whilst used in Australia, are also regularly used here in the UK. They most probably also originated here:

blower, bugger-all, go to buggery, up the duff, fag, pissed, wanker

Fag used to be pretty common in these Untied States, but I've not heard it lately.
I should add for Peta's sake my previously mentioning a place name near where I live: Wankers Corners. I'm sure she'd love it there!

I have only heard "fag" used. It's amazing how we all speak English, but have such different vocabularies.
