Dharawal

Dharawal National Park protects a significant area of sandstone heath and escarpment country on the southern edge of the greater Sydney basin, located between Campbelltown and the Illawarra coast south of Sydney. Covering approximately 14,900 hectares, the park preserves important examples of the Woronora Plateau sandstone vegetation communities, including heath, dry sclerophyll forest, and hanging swamps. The park is named after the Dharawal Aboriginal people, the traditional custodians of the area, and forms part of a significant belt of conservation land protecting the escarpment margin south of Sydney.

Dharawal National Park provides important wildlife habitat at the interface of the Sydney Basin and Illawarra regions. The threatened green and golden bell frog is present in the park's permanent water bodies. Glossy black-cockatoos feed on she-oak cones in the woodland. Eastern pygmy possums inhabit the heath and banksia communities. Common ringtail possums and brush-tailed possums are abundant. The hanging swamps on the sandstone plateau provide habitat for the endangered eastern chestnut mouse. Birdwatching in the heath and open woodland is excellent, with species typical of the southern Sydney sandstone landscape.

The vegetation of Dharawal National Park is characteristic of the Woronora Plateau sandstone, featuring scribbly gum and red bloodwood woodland on the ridges, with a diverse and species-rich heath understorey. The heath communities support a remarkable diversity of banksias, grevilleas, hakeas, and epacris species, with many species restricted to the Hawkesbury Sandstone flora. Hanging swamps on the plateau support the critically endangered sedge and sundew communities adapted to waterlogged, acidic conditions. Moist sheltered gullies contain turpentine and coachwood forest, sometimes grading into subtropical rainforest.

Dharawal National Park is underlain by Triassic Hawkesbury Sandstone and related Narrabeen Group sedimentary formations, which form the Woronora Plateau. The plateau edge is dissected by streams draining toward the Illawarra coast and the Georges River to the north, creating a landscape of sandstone ridges, cliffs, and sheltered gullies. The impermeable layers within the sandstone sequence cause perched water tables that support the hanging swamp communities on the plateau surface. The sandstone weathers along joints and bedding planes to produce the characteristic ledges and caves.

Dharawal National Park has a warm temperate climate influenced by both coastal and tableland conditions. Annual rainfall is approximately 1,000 to 1,200 millimetres, distributed through the year with a slight summer maximum. The plateau can be noticeably cooler and windier than the coastal plain below. Summer temperatures on the plateau are typically 25 to 32°C. Winters are mild, with overnight temperatures around 8 to 12°C and frosts possible on exposed sections of the plateau. Spring is the peak wildflower season, with the heath communities producing outstanding displays of colour.

The Dharawal people are the traditional custodians of the area now encompassed by the park, living in the coastal and escarpment country south of Sydney for tens of thousands of years. The park is named in recognition of their custodianship. The sandstone plateau and its abundant resources of food, water from the swamps, and shelter were important to the Dharawal way of life. European settlers moved into the region from the early 19th century, establishing pastoral properties in the surrounding district. The Illawarra Escarpment was identified as important habitat for wildlife conservation from the late 20th century.

Dharawal National Park was gazetted in 2012, relatively recently compared to many NSW parks, following advocacy for protection of the significant sandstone vegetation communities on the Woronora Plateau. The park consolidated several previous nature reserves and state conservation areas. It represents an important addition to the chain of escarpment parks south of Sydney, connecting with the Illawarra Escarpment State Conservation Area and other protected areas. Management focuses on weed control, feral animal management, and protection of the hanging swamp communities.

Dharawal National Park offers walking tracks through the sandstone heath and woodland, with excellent wildflower viewing in spring when the heath is at its most spectacular. The plateau rim provides views over the Illawarra coastal plain and the Tasman Sea. Hanging swamps are accessible via short walks from several entry points and provide fascinating examples of the perched wetland communities of the sandstone plateau. Birdwatching is productive in the heath and forest communities. The park's proximity to Campbelltown and the southern Sydney suburbs makes it an accessible wilderness escape for metropolitan residents.

Dharawal National Park is accessed from the Princes Highway south of Campbelltown, with several entry points via local roads. Day use facilities are available at some access points with parking, toilets, and picnic tables. There are no campgrounds within the park. The park is approximately 60 kilometres from the Sydney CBD. Campbelltown and Appin townships provide visitor services. A national parks pass applies. The park is a popular day trip destination for southern Sydney residents and can be combined with visits to the Illawarra Escarpment and Royal National Park.

Conservation priorities in Dharawal National Park include protecting the critically endangered hanging swamp communities from altered hydrology and invasion by invasive weeds. Bracken fern and exotic grasses are managed in areas where fire or disturbance has created openings. The green and golden bell frog population is monitored, and management aims to maintain the quality of permanent water bodies. Feral cats and foxes are controlled to protect ground-nesting birds and small mammals. The park's connectivity to adjacent protected areas on the escarpment is maintained through vegetation management on the boundary.
