Richmond River Light, Lighthouse in Ballina, Australia

Richmond River Light is a circular stone lighthouse at Ballina Head, on the northern side of the Richmond River entrance. Its cement-rendered, white-painted walls taper from 480 mm at the base to 360 mm at the top, around an internal diameter of 1.8 m. Twelve bluestone corbels carry an oversailing bluestone platform about 3.7 m up, reached by an iron stair, with a metal dome over the optical apparatus.

The tower was built between 1878 and 1880 following James Barnet's design and began operations with a fixed fourth-order light. The original beacon was visible for roughly 12 nautical miles.

The light shares its design with four other lighthouses James Barnet built in 1878–80: Fingal Head, Clarence River (demolished), Tacking Point and Crowdy Head. Its name comes from the Richmond River, whose northern entrance headland it marks; nearby Lighthouse Beach is named after it.

The site is open to the public and accessible, but the tower itself is closed. The light is operated by Transport for NSW and the grounds are managed by the New South Wales Department of Lands. A one-storey keeper's house still stands on the premises.

The light runs on a 1,000 Watt, 120 Volt tungsten-halogen lamp of 28,000 cd, backed by a battery standby. It shows four white flashes every 16 seconds. A steamer's masthead lantern with a 200 mm lens, raised on a wooden structure 30 metres away, works with it as a leading light into the Richmond River.
