I encounted a couple of interesting loos during my recent trip to Australia. This unusual example is at Jenolan Caves
, a couple of hours from Sydney. In fact, if you follow the link, this loo is situated underneath the enormous natural arch shown at the top right of the web page, close to the entrance to the Lucas cave. The imaginative siting of this loo, and the way they managed to fit in a third cubicle, are the major attractions here. They're otherwise pretty basic, but what do you expect for a cave?
