The Green Staircase in the Cape Naturaliste Lighthouse on Cape Naturaliste, Western Australia.
The lighthouse is in the south western region of Western Australia on the edge of Geographe Bay.
The lighthouse is a 20m cylindrical tower built in 1903 from locally quarried limestone.
The stairs came from Scotland and have reversible treads, so they can be flipped over when the top side becomes worn.
