History and Human Development
A causeway, built in 1899, crosses the Hacking River at Audley within the Royal National Park. Here, mangrove flats were cleared to make way for boat-sheds and accommodation in the late 19th century. A boatshed and picnic grounds remain at Audley, having been used continuously since. Visitors can canoe and kayak further upstream along the Hacking River or its tributary Kangaroo Creek.
The soft soils are vulnerable to erosion, which is exacerbated by bushwalking. Erosion is facilitated by relatively high rainfall in the Garrawarra State Conservation Area. Furthermore, runoff from the towns of Helensburgh, Otford and Stanwell Tops (which lie above the catchment) has also impacted on water quality in the river, resulting in increased turbidity and algal growth.
