  3.7 Changes and conservation over time
The following section details the changes and conservation efforts to have been carried out at Cape du Couedic Lighthouse since its construction.
The Brewis Report
Commander CRW Brewis, retired naval surveyor, was commissioned in 1911 by the Commonwealth Government to report on the condition of existing lights and to recommend any additional ones. Brewis visited every lighthouse in Australia between June and December 1912, and produced a series of reports published in their final form in March 1913. These reports were the basis for future decision-making for the individual lighthouses and provide a snapshot of the Cape du Couedic lightstation in the early 20th century.[xlii]
