Hunter Valley

Valleys

The Hunter Valley is one of the largest river valleys on the coast of New South Wales, Australia, carrying the Hunter River and its tributaries through highland areas to the north and south, between about 162 and 310 kilometers north of Sydney. It sits within the Sydney Basin, and its geology includes a transitional zone between two major rock formations marked by the Hunter-Mooki Thrust fault, which has raised the Brokenback Range. Covering 22,694 square kilometers and home to 682,465 people as of the 2021 census, the valley is best known today for its wineries and its coal industry, both tied to the region's underlying sedimentary rock. Population projections put the valley's residents above one million by 2031.

    The Hunter Valley, also commonly known as the Hunter Region, Newcastle Region, or simply Hunter, spans the region in central-eastern New South Wales, Australia, extending from approximately 162 km (101 mi) to 310 km (193 mi) north of Sydney.

    Strips of basalt found throughout the region also bear witness to the volcanic activity that has occurred in the history of this fault. The Permian rocks in the central and southeastern expanse of the Lower Hunter Valley were formed when the area was underneath a shallow marine estuary.
  • Associated With: Triassic, Article text, age Triassic
    The further north and west, towards the Brokenback Range and the Upper Hunter, the more Triassic sandstone that can be found leading eventually to the carboniferous rocks that form the northern boundary of the Hunter with the New England Fold Belt and the foothills of the Barrington Tops.

    At one time this fault was very geologically active and gave rise to the Brokenback range that feature prominently in the Hunter valley. Strips of basalt found throughout the region also bear witness to the volcanic activity that has occurred in the history of this fault.
