Norah Head Lighthouse || CENTRAL COAST

Norah Head Lighthouse was the last significant lighthouse built in New South Wales, a 27 m tower, completed in 1903 with monetary assistance /Hargraves of Noraville after considerable numbers of ships foundered on the coast near the headland.

Originally it was powered by a kerosene concentric wick lamp and still today it features a 2nd order bivalve Fresnel lens prism floating on a mercury bath. At first, the prism was rotated by descending weights, but the light was electrified in 1961 and fully automated in 1995.

The light flashes once in 15 seconds, and is visible to 27 nautical miles (50 km), the focal plane is located at 46 m above sea level. For coastal shipping, two additional light signals are shown: a red light in the northeast sector, emitted from 39 m above the sea and a green one towards southwest, emitted from 44 m; both are continuous.
