Bit of an obscure curiosity here, with a railway (well, tramway) connection...
During annual family holidays to the South Durras area, I have always been intrigued by what is obviously a disused steam boiler lying near the coastline. It's of a reasonable size but seems, to the untrained eye, to be quite unconnected with anything around it. Naturally most people working in the area have no knowledge and even less interest in its origins, so I had to do some digging.
Turns out that this whole area used to be very active with logging of native forests and there were many sawmills along the coastline. One such used to be here at Wasp Head. I eventually discovered that there was once a tramway running here from Durras Lake. Having been brought from the surrounding areas, sawlogs would be loaded by steam winch onto a paddlewheel punt, taken to South Durras then carried along a horse tramway to this sawmill (my rough guesstimates suggest that the tramway was about 2.5 - 3km in length).
This boiler had no direct connection to the winch or the tramway, but provided power to the sawmill itself. The mill stopped working during the depression of the 1920s, fell into dereliction and was eventually demolished. If you bush bash around the headland, you can find evidence of where the mill once stood but really the only very tangible remnant is this boiler, pretty much left where it stood.
It seems to me to have received some attention to make it safe but it's otherwise mouldering away where it lies.
