Brisbane Water National Park features fertile valleys which runs along the northern side of the Hawkesbury River towards Brisbane Water and the Pacific Ocean.

The Hawkesbury River, or Hawkesbury-Nepean River (Dharug: Dyarubbin) is a river located northwest of Sydney, New South Wales, Australia. The Hawkesbury River and its associated main tributary, the Nepean River, almost encircle the metropolitan region of Sydney. The river between Wisemans Ferry and the Pacific Ocean marks the boundary of Greater Metropolitan Sydney in the south and the Central Coast region to the north.

The Hawkesbury River has its origin at the confluence of the Nepean River and the Grose River, to the north of Penrith and travels for approximately 120 kilometres (75 mi) in a north–easterly and then a south–easterly direction to its mouth at Broken Bay, about 15 kilometres (9.3 mi) from the Tasman Sea. The Hawkesbury River is the main tributary of Broken Bay. Secondary tributaries include Brisbane Water and Pittwater, which, together with the Hawkesbury River, flow into Broken Bay and thence into the Tasman Sea north of Barrenjoey Head.

The Central Coast is a peri-urban region lying on the Pacific Ocean in northern New South Wales, Australia, just north of Sydney. The area is the third-largest urban area in New South Wales and the ninth-largest urban area in the country.

The Central Coast is generally considered to include the region bounded by the Hawkesbury River in the south, the Watagan Mountains in the west and Lake Macquarie, lying on the Sydney basin. The region is filled with subtropical national parks, forests and also encompasses the major coastal waterways of Brisbane Water, Tuggerah Lakes and southern Lake Macquarie. The region's hinterland has fertile valleys, rural farmland and wineries, and also includes the Watagan Mountains.

Gosford is a waterfront city at the northern end of Brisbane Water on the Central Coast in the state of New South Wales, Australia.
