Wailwan Region

Australian postcode 2357 is centred on Coonabarabran and includes a number of surrounding rural localities such as Bugaldie, Dandry, Gowang, Purlewaugh and Ulamambri, giving it a distinctly rural and regional character. The 2021 Census recorded 4,069 residents, with a relatively high median age of 50, and the area has a strong agricultural and pastoral base, with farming, grazing, local services and tourism contributing to the economy. Coonabarabran itself is an important small service centre on the Newell Highway between Dubbo and Narrabri, providing a hospital, government and community services, shops, fuel and employment services, while the surrounding countryside offers a spacious lifestyle with relatively low-density housing and access to the Warrumbungle National Park and its distinctive mountain landscape. The Warrumbungles also support the area’s reputation for astronomy, including the internationally recognised Siding Spring Observatory nearby. The climate is inland temperate, with warm to hot summers and cool winters, and distances between properties and larger centres mean that a car is highly important—the postcode averages 2 vehicles per dwelling. For SENA, 2357 is an interesting example of a dispersed rural community where a local Edge Node could connect agricultural businesses, households, government services and tourism while reducing the effects of geographic distance from larger regional cities.
