An Australian icon this. But this traditional looking dunny houses a smart modern composting toilet, not a metal pan that has to be emptied and buried once a week.
(And just so you know -- Redback Spider distribution map)
Up until my mid-teens I had never lived in a house with an outdoor dunny. We lived on farms, and had septic tanks, but when we moved into town, we got downgraded to a shed down the back of the garden because the small town we moved to didn't have a sewerage system until a few years later, in the late 70s.
The dunny in the photo above is at Brayshaw's Hut in Namadgi NP, ACT.
PS Chiotte (or more usually, chiottes) is French for dunny. (It amuses me that even when you are using slang it is not considered proper to refer to toilets in the singular in French.)
