, wrecked in August 1857, with the loss of 121 lives. The second was Catherine Adamson, two months later in October 1857, with a loss of twenty-one lives.

A committee of the Light, Pilot and Navigation Board took evidence in September 1857 and recommended the construction of a 30 feet (9.1 m) lighthouse on the inner South Head,
showing a fixed white light (F.W.), although a red light was also considered.

The lighthouse was designed by Alexander Dawson, the New South Wales Government Architect
