Certainly a shack! It's a nice rustic little place that is quite charming. The outdoor bath is of course lovely and was a highlight for us. It was great to sit outside with breakfast in the morning and enjoy the numerous local birds - we saw about 20 species including rosella, cockatoo, kookaburra and many more.
If you're staying in the winter months be sure to bring slippers / thongs as you access the bathroom / toilet via a brief step outdoors (it's not in the shack as I'd thought).
