              2.2         Site Inspection
              A site inspection was undertaken by Paul Prenzler and Courtney Wharton of RHDHV on 30 January 2023,
              to observe the site conditions and undertake field measurements of the beach.

              The ‘seaward toe of the frontal dune’ was mapped using a handheld GPS to assist with determining the
              erosion prone area width at the site. The ‘seaward toe of the frontal dune’ was determined based on the
              guidance provided in the ‘Coastal Hazards Technical Guide’ (Department of Environment and Heritage
              Protection, 2013) and the notes of NOS3A dated 8 July 2015 prepared by the Department of Environment
              and Science (refer Appendix B). Figure 1 shows the ‘seaward toe of the frontal dune’ on Sunshine
              Beach near the subject site.

              The distance from the rear property boundary of the site to the toe of the frontal dune approximately 60
              metres.

              2.3         Geotechnical Investigations
              The geotechnical conditions at the site have been undertaken by Tectonic Geotechnical Pty Ltd. The
              geotechnical investigation will include the design of the house foundations, including foundation type and
              capacity with consideration of potential beach erosion.

              2.4         Survey
              Survey of the site and adjoining beach system was undertaken by Minstaff Survey Pty Ltd on the 5th
              January 2023. The survey is presented in Appendix C.

              The survey has been supplemented with bathymetry survey captured in 2020 as part of the Great Barrier
              Reef project (Beaman, 2020) to describe the beach profile through the surf zone to the depth of closure.
