Alright alright.... so some places only got indoor toilets in the latter part of the 20th century - but we still got them!
Nothing like the word dunny.......there's a great book called Dinkum Dunnies - featuring all sorts of well, dinkum dunnies.....
Anyway dunny would be one of my more favourite Australian expression - "fair suck of the sav" would probably be the best in my opinion

"Off like a brides nightie" would have to be another one.......oh and for those who don't realise it "banging like a dunny door" means having lots of sex.......why you'd want to associate dunnies with sex is beyond me though....

- I remember having a coffee with my Irish American sister in law once and she needed to go to the toilet so I told her to ask the staff where the thunderbox is -- she looked at me twice but suspected I was puling her leg so wouldn't do it.......though we did once get an Estonian friend to always tell everyone when she was going she had to make like a dick and head.....
