The cultural significance of the lighthouse resides in its fabric, and also in its intangible aspects – such as the meanings people ascribe to it, and the connections to other places and things. The survival of its cultural value depends on a well-informed understanding of what is significant, and on clear thinking about the consequences of change. The Burra Charter35 sets out good practice for conserving cultural significance.
Criterion under 'Heritage Significance' refer to the criterion satisfied within the specific Commonwealth heritage listing (see section 5.1).

There are no AMSA artefacts located on-site at Swan Island Lighthouse.
Exhibiting similar stylistic features, both Swan Island Lighthouse, first lit 1845, and Goose Island Lighthouse, first lit 1846, were built by ex-convict Charles Watson and his team of prisoners. Both masonry towers were constructed of cement rendered rubble stone and fitted with a catadioptric lens with silvered mirrors (see figure 19). In 1872, Swan Island’s mirrors were removed and fitted in the Goose Island lantern room. Located on isolated islands, the two towers are situated approximately 54.5 km apart in Bass Strait and are considered to be the two major coastal lights operating north-east of Tasmania.
