Ah Ha! ..... I recognise that, it's Brayshaws Hut in Namagi NP. The attached happy snap shows how Barry cunningly hid most of the new tank and PVC pipe - just as he avoided the public toilet just up the hill. You can also see the difference between 'stand and shoot' and real photography. When I saw it there were birds nesting under the veranda near the chimney. More info here (the hut not the birds).
