Brisbane Water National Park, Nature reserve near Gosford, Australia

Brisbane Water National Park is a nature reserve on the Central Coast that covers a large area with diverse landscapes. The terrain features sandstone cliffs, patches of rainforest, and eucalyptus woodland that together create a varied environment.

The park area contains numerous rock engravings that show Indigenous peoples lived in this region for thousands of years. These ancient marks on stone are direct evidence of long human presence at this location.

The park protects a range of Aboriginal sites and extends the representation of rock art from the Sydney Basin into the national park system. The Darkinjung people are the traditional inhabitants of the area the park now covers. The engravings are part of that record, not a separate attraction.

The Great North Walk from Sydney to Newcastle crosses the park, and the walk to Pindar Cave starts at Wondabyne station, a request stop on the Central Coast line where trains stop only on demand. The Hawkesbury River Railway Bridge and sections of the Pacific Highway and M1 Motorway cut through the park, so check access points before setting out.

The donkey orchid (Diuris bracteata) was listed as extinct under Commonwealth status before being recorded again in the park's dry sclerophyll woodland with grassy understorey. Of the 814 plant species recorded here, ten are considered rare, and all twenty vegetation communities are listed as endangered under the NSW Threatened Species Conservation Act 1995.
