Estuary

This region stretches from Richmond to the river's mouth at Broken Bay and includes the coastal strip of Pittwater.

The estuary is a major economic and recreational resource for Sydney. It supports NSW's second largest commercial estuarine trawl industry and is home to a major oyster industry. The region also supports considerable agriculture and tourism activities such as recreational boating and fishing.

The head of the estuary owes its remarkable beauty to being a drowned river valley. It also has many reserves fringing its waters including Kur-ing-gai Chase, Brisbane Waters, Bouddi, Marramarra, Dharug and Popran National Parks.

Mooney Mooney Creek and Mangrove Creek provide significant water supplies to the Central Coast.

The CMA's Estuary Investment Program targets the lower estuary, downstream of Wiseman's Ferry.
