Sandstone vegetation forest and heath could be found between the Turpentine-Ironbark Forest and Floodplain Forest within the suburbs of Hurlstone Park, Dulwich Hill and South Marrickville.

This vegetation contained a variety of edible plants including fruits, tubers, flower nectar, macrozamia seeds, and starches from ferns. (Benson,1999). Bark fibers from palms and rushes could have been used for weaving. Grass Tree (Xanthorrhoea) species also grew in this vegetation community. Xanthorrhoea has a flowering stem, which was used as spear shafts and resin that was used has a hafting agent. In the Hawkesbury Sandstone small quartz pebbles were found which could be flaked to produce useful tools.

Overhangs created by cavernous weathering or blockfall in exposed Hawkesbury Sandstone outcrops and clifflines provided natural shelters from the weather that were utilised by Aboriginal people in the Sydney coastal area. Hawkesbury Sandstone was also used as a medium to engrave and paint images and for sharpening axe heads.
