Tasmania to serve as a LaPlace Azimuth and Geodial station. The results of this national survey determined the Australian Geodetic Datum in 1966, the first whole-of-continent consistent geodetic datum in the world.
  3.11          Unresolved questions or historical conflicts
Dates on various alterations made to the lighthouse are also relatively unknown. Little is known about features such as the engine house, the first telephone connection, and flagstaff, in terms of when and why their installation took place.
  3.12          Recommendations for further research
The location of the small village constructed to house the 70 odd workers during construction of the lighthouse is unknown. Research into its location may provide beneficial insight into the early European social history of the site.
Further research into the alterations made to the lighthouse throughout the 19th and 20th centuries would also benefit a greater understanding of the lightstation's history and heritage values.

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