Here are some other ways "dunny" is used:
* A simple toilet: Even if it's not outside, it can be used to refer to any basic toilet.
* A shed: Sometimes, "dunny" is used to refer to a small outbuilding or shed.
* A place of isolation: Due to its association with outdoor toilets, "dunny" can be used humorously to describe a place that's secluded or remote.
So, when someone in Australia or New Zealand talks about the "dunny", you'll know they're referring to the bathroom, or at least the toilet!
