2014). These include: Natural Zone - This consists mainly of the revegetated Mount Trefle and its western slopes and includes most of the heavily wooded indigenous plantings. It also includes Bottle and Glass Point to the north and the steep and dense scrublands above the western shore area. Parkland Zone - This includes all of the grassed lower areas, the beachfront and the slopes up to Greycliffe House (but not the garden). It contains most of the large lawn areas, introduced trees and paving, and many of the buildings on the site. Greycliffe Garden Zone - This small zone includes the remnant gardens of "Greycliffe House" and those adjacent to the Margaret Harper Wing which incorporates a parterre garden. Military Zone - This consists of Steele Point and contains the above ground and subterranean remains of the Battery and its associated buildings. It is noted that military activity at times included a number of sites in the Park. Utility Zone - This includes the NPWS workshop situated in the old stone quarry near the entrance of the original access road from Vaucluse Road. Aboriginal sites The site, with its accessible location, fresh water supply and wealth of resources constitutes an Aboriginal cultural landscape. Extensive archaeological evidence at Nielsen Park demonstrates use of the land for camping and fishing over an extended period. There are fourteen recorded Aboriginal sites within the park. These sites are comprised within: A small cavity in the base of sandstone escarpment at the north-eastern end of Shark Beach. Two red ochre positive hand stencils are located on the rear wall of the stone cavity. The hands (both left and right) are approximately wide and long. No archaeological deposits are present within the site. The cavity floor is sandstone. A small sandstone overhang on an upper terrace of a sandstone escarpment at the north-eastern end of Shark Beach (photo to left shows site location). The overhang is approximately long, high and wide. The site is approximately above sea level. One white ochre negative hand stencil is located on the rear wall of the shelter. Only one left hand is present, no other art was identified. A thin residual midden deposit covers the shelter floor. The deposit contains the remains of a variety of shellfish species, dominated by rock oyster, mud whelk and cockle. Charcoal and pieces of quartz (probable stone artefacts) are also included within the deposit.
