The Green Cape Lighthouse is a lighthouse located at the tip of Green Cape which forms the northern boundary of Disaster Bay in southern New South Wales. It is the southernmost lighthouse in New South Wales and also Australia's first lighthouse built in concrete. It was partly constructed by Albert Aspinall in 1881 using a seven-kilometre wooden tramway he built from Bittangabee Bay to transport the materials. His untimely death left others to complete the construction. Eventually in 1883 the facility was activated, using a first order Fresnel lens.
In 1992 the old lighthouse was decommisioned. A modern steel pylon right next to the historic tower emits a double flash every 15 seconds from a focal plane height of 39 m above sea level.
