Archaeological Assessments
In February 2005, The Harbour Trust engaged archaeologists Casey & Lowe to prepare a detailed history and archaeological assessment.

The report concluded that the site has the potential to contain rare archaeological remains of historic, associative and social significance, as well as a high level of research potential at a National level of significance. These potential remains relate to the continuous use of the highest parts of South Head as the location of a marker and signal beacon from 1790 to the present day – see Figure 12.

The report made the following recommendations:

       * the impacts from remediation of the site should be minimised;
       * the remediation program should be preceded by archaeological testing so as to refine the understanding of the archaeological issues and provide more certainty for the management of the resource; and
       * in order to inform the proposed program of remediation, archaeological testing should concentrate on determining the extent of remains and the nature of the fills on-site in areas where remediation is required.

As a result of these recommendations, the Harbour Trust engaged Casey & Lowe to dig archaeological test trenches on the site to answer questions about the site formation and the soil strata. Foundations of the Greenway lighthouse as well as the north and south compound wall were uncovered. Foundations of the western corner pavilions were not located due to extensive soil disturbance; however their location can now be predicted with greater accuracy due to the uncovering of the compound wall footings.

The results of the test trenching indicated that up to 150mm, 200mm in some areas, of current turf and topsoil cover could be removed, if required for remediation and replaced without impacting on archaeological remains. Archaeological monitoring of any soil removal would also be required.

Fabric Assessments
In 2005 The Harbour Trust engaged the NSW Government Architects' Office to undertake a detailed survey of the stone remains on the site, including the Greenway compound wall and the remains of the Engineer and Assistant's Quarters.

The Greenway wall was surveyed by architects, a master mason and a specialist structural engineer. It was recorded stone by stone in a drawn and photographic record. The physical evidence on-site revealed that the eastern portion of the Greenway compound wall had crenellations in the top coursing located between the two corner lodges. This is a typical detail used by Greenway. Other examples of such crenellations existed at Dawes Point Battery and Fort Macquarie. The survey also revealed that the wall is in a fragile state and recommended that for structural stability the stones should be re-pointed. Other conservation
