Before construction could begin, a jetty was built in Weirs Cove, north of the lighthouse, and a
flying fox erected to haul the materials up the cliff. afterwards moving to
Troubridge Island Lighthouse for a few years. By the 1950s, shipping around Cape du Couedic had decreased significantly, with most vessels using the
Backstairs Passage and
Investigator Strait, so Cape du Couedic was automated in 1957, no longer requiring keepers. The First Order lens, complete with mercury float pedestal, was removed and replaced by a Third Order fixed lens, lit by
acetylene gas. The lighthouse was
heritage-listed on the
SA Heritage Register on 24 July 1980. In 1991 restoration work on the three
lighthouse-keeper's houses was undertaken, after which they became available for holiday rentals. In 2000 further work was carried out, including the replacing the roofs with
slate roofs, true to the original. ==Description==
