Cape Naturaliste was named for a ship of the French Baudin Expedition of 1800. It's a prominent location, overlooking Geographe Bay on one side and the vastness of the Indian Ocean on the other. The high ground made it the perfect location for a lighthouse, guiding ships through the sometimes treacherous waters surrounding the Cape. During WW2 it was the operational position for the Royal Australian Air Force (RAAF) 33rd Radar station, a link in the air defence chain protecting the South West Sector of Western Australia.
