- NATURAL RESOURCE MANAGEMENT STRATEGY FOR THE NORTHERN AGRICULTURAL REGION OF WESTERN AUSTRALIA
The western edge of the Shire of Chapman Valley extends along the Indian Ocean coast north of Geraldton. The coastline includes sandy beaches, coastal dunes, limestone features, river and creek mouths and nearshore reef systems, with Coronation Beach one of the best-known coastal locations. Nearshore reefs and limestone pavements provide important marine habitat for reef fish, invertebrates and Western Rock Lobster. Coastal dunes and native vegetation provide terrestrial habitat and help protect the shoreline, while river and creek mouths create additional coastal environments. The coast is valued for recreation and tourism, including fishing, boating, swimming, snorkelling, surfing, windsurfing and camping. Coronation Beach is particularly important for windsurfing and other water-based recreation. Coastal erosion, sea-level rise, recreational pressure and future land-use change require ongoing management. Parts of the coastline around Oakajee are also identified for port and industrial purposes, making careful planning important for balancing environmental, recreational and development values.

Agriculture is the foundation of the Shire of Chapman Valley economy. Broadacre cropping and livestock production dominate much of the rural landscape and support agricultural services, grain handling, transport and other local businesses.
The Shire’s proximity to Geraldton strongly influences its economy. Many residents travel outside the Shire for employment and services, while access to Geraldton provides businesses and agricultural producers with connections to major transport, processing, commercial and service infrastructure.
Tourism and agritourism provide opportunities for economic diversification. Visitors are attracted by the Chapman Valley’s rural landscapes, wildflowers, heritage, local produce, events, coastal environments and outdoor recreation.
Future development associated with the Oakajee Strategic Industrial Area and regional energy and infrastructure investment may also create economic opportunities for the Shire. Current economic-development planning seeks to strengthen existing industries while encouraging tourism, small business and other forms of sustainable economic diversification.
The Shire of Chapman Valley has a varied geological and physical landscape extending from the coast eastwards across the Chapman Valley, Moresby Range and Victoria Plateau. Much of the area is underlain by ancient granitic basement rocks overlain in places by younger sedimentary rocks and surface deposits.
The eastern part of the Shire includes the broad Victoria Plateau, with extensive sandplains, ancient drainage valleys and areas of lateritic terrain. The Chapman River and its tributaries have dissected the landscape further west, creating broad valleys, rounded hills and slopes, with areas of exposed weathered granite and younger alluvial deposits.
The Moresby Range forms a distinctive series of flat-topped hills and mesas in the western Shire. These are remnants of the Victoria Plateau, with sedimentary rocks overlying older granitic basement and lateritic duricrust forming resistant caps on parts of the range. Along the coast, older Tamala Limestone and associated dunes are overlain in places by younger calcareous dunes of the Quindalup system.
Soils vary considerably across these landscapes and include deep yellow and red sands, sandy and loamy duplex soils, lateritic gravels, alluvial loams and clays, and calcareous sands associated with the coastal dune systems.
The Shire lies predominantly within the Geraldton Hills (GES01) subregion of the Geraldton Sandplains IBRA bioregion. Native vegetation includes species-rich shrublands and heathlands, Acacia shrublands, mallee and eucalypt woodlands, with distinctive vegetation communities associated with the Moresby Range and coastal limestone landscapes.
Several Priority Ecological Communities occur within the Shire. The Plant assemblages of the Moresby Range system are recognised as a Priority 1 ecological community in Western Australia. The community includes Melaleuca megacephala and Hakea pycnoneura thickets on stony slopes, Verticordia-dominated low heath and other shrublands associated with the lateritic landscapes of the Moresby Range.
Coastal parts of the Shire also support Priority 1 ecological communities associated with Tamala Limestone and coastal sands. These include Frankenia pauciflora low open shrublands in swales, which occur on the lower slopes and swales of Tamala Limestone ridges, and coastal vegetation dominated by Acacia rostellifera and mallee eucalypts.
The nationally listed Subtropical and Temperate Coastal Saltmarsh ecological community also occurs in coastal parts of the Shire. It is listed as Vulnerable under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 and comprises salt-tolerant vegetation associated with intertidal and supratidal coastal environments.
Agriculture is the dominant land use across much of the Shire of Chapman Valley, with broadacre cropping and livestock production occupying extensive areas of the Chapman Valley and the inland country towards Yuna. Agricultural production is supported by grain handling, transport infrastructure and agricultural services.
Closer to Geraldton, land use becomes more diverse and includes rural-residential and rural-smallholding development, particularly around the western and south-western parts of the Shire. Urban and community services are concentrated in settlements including Nabawa, Nanson and Yuna.
The Shire also contains areas of significant native vegetation, waterways, coastal environments and conservation land. The Moresby Range, Chapman River corridor, coastal reserves and other areas of remnant vegetation provide important habitat and ecological connections through an extensively modified agricultural landscape.
Industrial, infrastructure and resource-related land uses also occur or are planned in parts of the Shire, particularly around Oakajee. Land-use planning therefore seeks to balance productive agriculture, settlement and economic development with protection of landscape, biodiversity, water resources and other environmental values.
The Shire of Chapman Valley has a dispersed population living across rural properties, small settlements and rural-residential areas, particularly in the western part of the Shire near Geraldton. Nabawa is the Shire’s administrative centre, while Nanson and Yuna are smaller communities serving the surrounding agricultural areas.
At the 2021 Census, the Shire of Chapman Valley had 1,556 residents. The median age was 44 years, and 74 people — 4.8% of the population — identified as Aboriginal and/or Torres Strait Islander.
The Shire’s proximity to Geraldton influences where residents work and access services, while local community organisations, sporting clubs, events and volunteering contribute strongly to community life across the Shire.
The Chapman River is the principal waterway of the Shire of Chapman Valley. Its headwaters occur around Yuna and the Victoria Plateau, from where the river and its tributaries flow west through the agricultural landscape and Chapman Valley before reaching the Indian Ocean in Geraldton. River flow is strongly influenced by seasonal rainfall and groundwater. The Chapman River is largely a gaining river, with groundwater contributing to surface flows along much of its length. The river and its riparian vegetation provide important habitat and ecological connections through an extensively cleared agricultural landscape. Water conditions vary considerably across the Shire. In the eastern areas around Yuna, ancient broad drainage valleys contain saline soils, salt pans and ephemeral lakes, while groundwater can vary from fresh to saline. Closer to the coast, smaller ephemeral waterways include the Buller River, Oakajee River, Oakabella Creek and Woolawar Gully. Salinity, erosion, sediment movement, altered drainage and water quality are important management issues within the agricultural catchment. Reliable water supplies are also important for farming communities, particularly during dry periods, making sustainable water use and maintenance of strategic community and agricultural water supplies important for the Shire.
| River | Length (km) | Catchment | Key Characteristics |
| Buller | 10 | 33.9 | The Buller River head waters rises 25 km north of Geraldton and meanders in a southerly directions before discharging into the Indian Ocean approximately 4 km north of Drummonds Cove. |
