Oh dear, I noticed that I posted Rylstone twice so have slotted my very last town Darby's Falls into this spot.
Darby's Falls is a small village (population 70) on the road between Cowra and the water playground at Wyangala Dam. The school is closed and there are just a few houses. We noticed there is an astronomical observatory there too.
Apparently it has a gold mining history and like a lot of these old gold towns is currently the focus of new exploration for other minerals.
