           7.1     Method used to reduce depths to datum
           Depths were determined relative to the GDA2020 ellipsoid and reduced to AHD by use of
           AUSGeoid2020.

                  Survey vessel
           The vessel used for this survey was a 3.3m Yamaha Waverunner PWC, SandXplorer. This vessel
           is commercially registered through AMSA in 2C survey. The transducer is mounted on a fixed
           mount to the starboard side aft with a GNSS antenna pole located directly above, not requiring
           any horizontal offsets. Offset to the transducer from the antenna is fixed at 1.335m.
