The lllawarra Escarpment State Conservation Area protects a geologically and climatologically unique landscape. The lllawarra escarpment is the dominant landform of the lllawarra region.
Illawarra Escarpment State Conservation Area occupies nearly 30% of the Illawarra escarpment and a sliver of the eastern edge of the Woronora Plateau. The park comprises 6 separate sections extending over approximately 40 kilometres, from Stanwell Park in the north to West Dapto in the south. The 6 sections are in the localities of Stanwell Park, Austinmer–Bulli, Corrimal, Mount Keira, Mount Kembla and Wongawilli.
The escarpment between the park sections consists of private land and land managed by Wollongong City Council. Land uses include recreation reserves, private dwellings and coal mining operations. To the west of the escarpment most of land is managed by WaterNSW for the provision of water to Sydney and the Illawarra regions (the Metropolitan Special Area). Wollongong and its suburbs lie adjacent to the eastern boundary of the park.
