Point Perpendicular Light is a lighthouse located on Point Perpendicular, a point at the southern tip of the Beecroft Peninsula, in New South Wales, Australia. It marks and the northern entrance to Jervis Bay. The historic lighthouse was active from 1889 to 1993 and is still present, though its future is unclear. It is believed to be the first lighthouse in New South Wales which was built of precast concrete blocks. The light was replaced in 1993 with a skeletal tower which is active.
Point Perpendicular Lighthouse was built to replace Cape St George Lighthouse which was inadequately located on the southern entrance to Jervis Bay, a fact which was apparent since its construction in 1860. Suggested places for replacing the light were on Bowen Island or Crocodile Head. Point Perpendicular was chosen in September 1883 by Colonial Architect James Barnet and Captain Francis Hixson of the Marine Board.
The plans for the lighthouse were signed on 18 March 1897. The lighthouse was designed by James Barnet's successor, Charles Assinder Harding, who also later designed Cape Byron Light and Norah Head Light, in a style similar to Barnet's.
Tenders were called on 15 April 1897, and by September 1897 construction has started. Most of the materials were landed at Bindijine Wharf, about 8.0 kilometres (5 mi) northwest, which was constructed in 1898. Horse and cart were then used to transport them to the site.
The light was first lit on 1 May 1899. The original light source was a vaporized kerosene lamp with an intensity of 100,000 cd and a visible range of around 33 kilometres (21 mi). The apparatus installed was a massive Chance Bros. 920 millimetres (36 in) three faceted 1st order Fresnel lens, weighing 33 tonnes (32 long tons; 36 short tons), and the original light characteristic was a white flash every 20 seconds (Fl W 20s). The lens is still installed in the lighthouse.
