History

The first recorded recommendation for building a lighthouse to guard Seal Rocks was made by a committee of the New South Wales Legislative Assembly in 1863. Original intentions were to place the lighthouse on the Rocks, but because of access difficulties the location finally chosen in 1873 was Sugarloaf Point. The lighthouse was designed by James Barnet, the New South Wales Colonial Architect of the time. Tenders were called in 1874. Construction required building a 1500 feet (457.2 m) long jetty

This secondary light is positioned at a lower height, and was originally green, changed to red in the 1980s.
