Wellington Caves & Phosphate Mine
Heading out of Dubbo in the afternoon, we weren't entirely sure where we were going to stay that night, but a stop in the tourist information centre in Wellington decided us on Wellington Caves. We rocked up to the caravan park there, found a cabin - it wasn't at all crowded - and cooked ourselves dinner.
In the morning we ate breakfast while watching King Parrots in the grass and being investigated by a juvenile magpie. We then looked at the Japanese garden -- which was pretty uninspiring after Cowra's! -- and an exhibition about the caves. The cave we toured is mostly filled in, with a flat sandy floor at the bottom, and its formations are not nearly as nice as those we'd seen at Wombeyan.
The phosphate mine was more fun. The guide explained how it was basically a scam, designed to lure investors and to give several hundred "essential workers" a way of avoiding conscription (the operating years of the mine pretty much matched the First World War). There are also some areas with masses of bones, which have attracted palaeontologists.
