Tillegra Dam was a proposed dam on the Williams River to be located 20 km (12 mi) northwest of Dungog, in the Hunter Region of New South Wales, Australia. It was first proposed in the 1970s but a formal proposal was not announced until 2006. Community opposition and changing needs saw the end of the proposal in November 2010. Hunter Water Corporation divested itself of its Tillegra landholding in 2015, permanently ending the proposal.
The Tillegra Dam was first proposed by the Hunter Water Corporation in the 1970s, but was deferred indefinitely in the 1980s due to the success of user pays pricing.On 13 November 2006, the NSW Government announced proposals for a A$300 million dam at Tillegra to supply water to the Lower Hunter Region and Central Coast. The justification for the dam was based primarily on climate change and population growth in the Hunter Region.
The No Tillegra Dam Group was formed to prevent the building of the dam. Opponents claimed the dam proposal was grossly excessive for need, will drown valuable agricultural land and greater water efficiency, demand management and recycling would eliminate the need for the dam.
On 28 November 2010 then NSW Premier, Kristina Keneally, announced the cancellation of the dam after the Planning Minister refused to approve it.The refusal was based on both the potential for environmental damage and the lack of proper consideration of alternative water security measures. The state government had already spent $100 million on the project.
The Hunter Region, also commonly known as the Hunter Valley, is a region of New South Wales, Australia, extending from approximately 120 km (75 mi) to 310 km (193 mi) north of Sydney. It contains the Hunter River and its tributaries with highland areas to the north and south. Situated at the northern end of the Sydney Basin bioregion, the Hunter Valley is one of the largest river valleys on the NSW coast, and is most commonly known for its wineries and coal industry.
The Murray–Darling basin is a large geographical area in the interior of southeastern Australia, encompassing the drainage basin of the tributaries of the Murray River, Australia's longest river, and the Darling River, a right tributary of the Murray and Australia's third-longest river. The basin, which includes six of Australia's seven longest rivers and covers around one-seventh of the Australian landmass, is one of the country's most significant agricultural areas. Located west of the Great Dividing Range, it drains southwestly into the Great Australian Bight and spans most of the states of New South Wales and Victoria, the Australian Capital Territory, and parts of the states of Queensland and South Australia.

It has three spillways across the Murrumbidgee River located in the South West Slopes region of New South Wales, Australia. The dam's purpose includes flood mitigation, hydro-power, irrigation, water supply and conservation. The impounded reservoir is called Lake Burrinjuck. It was designed by Lawrence Augustus Burton Wade and built from 1907 to 1927 by Lane & Peters, Sydney. It is also known as Barren Jack Dam and Barrenjack. The property was owned by Department of Planning and Infrastructure. It was added to the New South Wales State Heritage Register on 2 April 1999.
Raymond Terrace is a town in the Hunter Region of New South Wales, Australia, about 26 km (16 mi) by road north of Newcastle on the Pacific Highway. Established in 1837 it is situated at the confluence of the Hunter and Williams rivers. The town was named after Lieutenant Raymond, who had explored the Hunter River in 1797 and described the terraced appearance of trees in the area. Governor Lachlan Macquarie camped in the area in 1818, using "Raymond Terrace" as the name for the place where his party had camped.
Port Stephens Council is a local government area in the Hunter Region of New South Wales, Australia. The area is just north of Newcastle and is adjacent to the Pacific Highway which runs through Raymond Terrace, the largest town and Council seat. The area is named after Port Stephens, which is the major geographical feature of the area. It extends generally from the Hunter River in the south, to near Clarence Town in the north, and from the Tasman Sea in the east, to just south of Paterson in the west. The mayor of Port Stephens Council is Ryan Palmer. Port Stephens is about two and a half hours north of Sydney.
The Hunter Expressway is a 39.5-kilometre (24.5 mi) long controlled-access highway in New South Wales, Australia. It was previously known as the F3 to Branxton link or Kurri Kurri Corridor during the planning stage. It has two lanes in each direction, running generally north west from the Pacific Motorway at the Newcastle Link Road interchange to the eastern end of the Belford Bends Deviation on the New England Highway north of Branxton. The road allows traffic to bypass the Maitland area, Lochinvar, Greta and Branxton. The expressway opened on 22 March 2014.

Port Bonython is the location of a deepwater port, gas fractionation plant and diesel storage facility west of Point Lowly in the Upper Spencer Gulf region of South Australia. It lies 16 km east-northeast of Whyalla, South Australia and approximately 370 km north-west of the State's capital city, Adelaide. The existing wharf is 2.4 kilometres long and is capable of berthing small Capesize ships with a maximum capacity of 110,000 tonnes. The wharf was established in 1982 and named after John Bonython, the founding chairman of Santos. The structure is leased to Santos by the Government of South Australia and is used for the export of hydrocarbon products. An oil spill at Port Bonython in 1992 resulted in loss of bird life and damage to mangrove habitats to the west and southwest of Port Pirie.
As Australia's supply of freshwater is increasingly vulnerable to droughts, possibly as a result of climate change, there is an emphasis on water conservation and various regions have imposed restrictions on the use of water.
Water security in Australia became a major concern in Australia in the late 20th and early 21st century as a result of population growth, recurring severe droughts, effects of climate change on Australia, environmental degradation from reduced environmental flows, competition between competing interests such as grazing, irrigation and urban water supplies, and competition between upstream and downstream users. For example, there is competition for the resources of the Darling River system between Queensland, New South Wales and South Australia. Water reform was first placed on the national agenda at the 1994 Council of Australian Governments (COAG) meeting when a strategic framework was devised. As the knowledge of surface and groundwater systems grew and the awareness of the significance of sustainable water markets increased, further water reform was agreed to at the 2004 COAG meeting, under a national blueprint known as the National Water Initiative (NWI).
