Cape Naturaliste, in the south west of Western Australia, is the site of a lighthouse which was activated in 1904.{{cite news |url=http://nla.gov.au/nla.news-article147670896 |title=Opening Cape Naturaliste Lighthouse. |newspaper=The South-Western News |location=Busselton, Western Australia |date=8 April 1904 |access-date=7 December 2015 |page=4 |via=National Library of Australia}} It was automated in 1978, but remained manned by a lighthouse keeper until 1996.{{cite loa|WA|Cape%20Naturaliste|The Cape Naturaliste Lighthouse}}

It is a {{convert|20|m|ft|adj=mid|-high}} cylindrical tower built of limestone that still uses its original first order Fresnel lens made by Chance Brothers. The light characteristic is "Fl. (2) 10 s", i.e. a group of two flashes every ten seconds, the focal plane is at {{convert|123|m}} above sea level. Another precious lens optic is displayed there, the second order Fresnel lens of the Jarman Island Light, as well as the original Great Sandy Islands beacon.{{Cite book|url=https://museum.wa.gov.au/maritime-archaeology-db/maritime-reports/lighthouses-western-australian-coast-and-shore-islands|page=26|last=Cumming|first=D.

The lighthouse is constructed of limestone quarried from nearby Bunker Bay, which was also known as the Quarries.
