Why do we call this beautiful estuary Brisbane Water? Brisbane Water is not just a scenic location. It has a rich history. Let’s uncover some of its secrets.
Brisbane Water is a wave-dominated barrier estuary. It is located in the Central Coast region of New South Wales. This waterway begins at the meeting of Narara and Coorumbine Creeks. These creeks are southeast of Gosford. Brisbane Water travels approximately 18 kilometers south. It flows to its mouth at Broken Bay. This is about 7 kilometers from the Tasman Sea. Barrenjoey Head marks this point.
Many towns and suburbs dot the shores of Brisbane Water. These include Gosford and Woy Woy. Ettalong Beach and Kincumber are also nearby. Blackwall and Booker Bay add to the community.
Several islands lie within Brisbane Water. St Huberts Island is one. Rileys Island and Dunmar Island are others. Pelican Island also sits within its waters.
Adjoining the estuary are national parks. Brisbane Water National Park lies to the west. Bouddi National Park sits to the east. Kincumber Broadwater is a separate basin connected to Brisbane Water. It lies east of Davistown. The total catchment area is approximately 165 square kilometers.
For thousands of years, Aboriginal people occupied the land. The Darkinjung and Kuringgai peoples lived here. They used the estuary and foreshore for cultural purposes.
In 1825, Brisbane Water received its name. It honored Sir Thomas Brisbane. He served as the Governor of New South Wales from 1820 to 1825.
Brisbane Water holds significance for the Darkinjung and Kuringgai people. Daleys Point area is one such place. Staples Lookout is another significant site. It is located west of Woy Woy. Bungaree, a leader of the Kuringgai tribe, assisted early colonial explorers. He also aided Phillip Parker King and Matthew Flinders. They were circumnavigating Australia.
In the 20th century, European settlement brought ferries. They served an isolated orphanage. Commuter services ran from Gosford to Woy Woy. Another ferry operation carried farm produce. Commuter ferries between Brisbane Water townships stopped in 1971. Today, Central Coast Ferries operates the only ferry service. It serves Empire Bay, Davistown, Saratoga and Woy Woy.
In 1973, Rileys Island residents requested a green ban. A company planned to remove native vegetation for construction.
Brisbane Water’s estuary and foreshores have high scenic value. There are areas of untouched vegetation. Many locations offer extensive water views. Beaches, inlets and bays stand out. Bushland-covered hills lie in the distance. Vantage points allow the public to experience Brisbane Water’s landscape.
The average bed level is about 5 meters. Often, it is as low as 3 meters. Brisbane Water is mostly shallow. The tidal impact is approximately plus or minus 0.4 meters. The inlet narrows at The Rip near Ettalong Beach. The Rip has a fast tidal current.
The oyster industry is vital to the local economy. In 2007-2008, about 250,000 dozens of oysters were produced. This was worth A$1.3 million. It represented about 3.6% of the NSW industry total.
Over 110 bird species were recorded in 2009. Sixty were vulnerable. Fourteen were endangered. Sixteen plant species were vulnerable. Eight were endangered. BirdLife International classifies 2,277 hectares of Brisbane Water as an important bird area. It has a population of bush stone-curlews. Sometimes it supports regent honeyeaters and swift parrots. They visit during autumn and winter when swamp mahogany trees flower.
So, as you gaze upon Brisbane Water, remember its layers of history. From Aboriginal heritage to colonial governors, it is all here. From oyster farming to bird conservation, it is a place of natural beauty and economic importance. Brisbane Water is more than just water. It is a story etched in time.
