- NATURAL RESOURCE MANAGEMENT STRATEGY FOR THE NORTHERN AGRICULTURAL REGION OF WESTERN AUSTRALIA

Agriculture is the foundation of the Shire of Mingenew economy. Broadacre cropping and livestock production dominate the surrounding rural landscape and support agricultural services, transport, grain handling and other local businesses.
Mingenew is an important grain receival and agricultural service centre for the surrounding farming district. The town provides businesses and services supporting agriculture as well as local government, education, health, retail, hospitality and other community services.
Tourism also contributes to the local economy, particularly during the wildflower season. The Shire’s distinctive breakaway landscapes, wildflowers, rural character and community events attract visitors to Mingenew and the surrounding district.
The Shire is also seeking to diversify its economy and attract new investment and employment, including opportunities associated with the wider Mid West resources and renewable-energy sectors.
The Shire of Mingenew lies within the northern Perth Basin and is predominantly underlain by sedimentary rocks. These include Mesozoic sedimentary units such as the Yarragadee Formation and other sandstone, siltstone and shale sequences, overlain in places by younger alluvial and colluvial deposits associated with river valleys and drainage systems.
The landscape includes broad sandplains and gently undulating country, together with dissected valleys, low hills, breakaways and alluvial flats associated with the Irwin River and its tributaries. Soils vary across these landscapes and include deep sandy soils, sandy gravels, loamy earths and duplex soils, with heavier clay and alluvial soils occurring in lower-lying areas and along drainage systems.
The Shire lies predominantly within the Geraldton Hills (GES01) subregion of the Geraldton Sandplains IBRA bioregion. Native vegetation includes Acacia shrublands and eucalypt woodlands, together with species-rich shrublands and heath vegetation associated with sandy and lateritic landscapes. York gum (Eucalyptus loxophleba) and jam (Acacia acuminata) are characteristic of parts of the inland landscape.
The Clay flats assemblages of the Irwin River as originally described in Beard (1976)* historically occurred on clay flats associated with the Irwin River in the Mingenew-Irwin area. Previously described as a presumed totally destroyed threatened ecological community, it was formally listed in 2025 under Western Australia’s Biodiversity Conservation Act 2016 as a Collapsed ecological community.
The community historically comprised sedgelands and grasslands with patches of York gum (Eucalyptus loxophleba) and scattered river gum (Eucalyptus camaldulensis) over shrublands including Acacia acuminata and Acacia rostellifera. Although the community is now classified as collapsed, remnants of native vegetation and riparian habitat associated with the Irwin River and its tributaries remain important components of the Shire’s landscape.

Agriculture is the dominant productive land use across the Shire of Mingenew, with broadacre cropping and livestock production occupying much of the cleared landscape. Agricultural infrastructure, grain handling, transport routes and rural services support farming across the district.
Urban, commercial and community land uses are concentrated in the Mingenew townsite, with smaller settlements, rural properties and agricultural infrastructure distributed throughout the Shire. Extractive industries and other rural land uses also occur locally.
Areas of remnant native vegetation occur throughout the agricultural landscape, including within conservation reserves, along waterways and roadsides and on breakaway country. These areas provide important habitat for native flora and fauna and contribute to ecological connectivity across an extensively cleared landscape.
The Shire’s natural areas are also important for their spectacular seasonal wildflowers, which are a significant environmental and tourism value for Mingenew and the surrounding district.
The Shire of Mingenew is a small rural community centred on the Mingenew townsite, with residents also living on farms and rural properties throughout the district. Mingenew provides local government, agricultural, education, health, retail, hospitality and community services for the surrounding farming area.
At the 2021 Census, the Shire of Mingenew had 407 residents. The median age was 47 years, and 23 people — 5.7% of the population — identified as Aboriginal and/or Torres Strait Islander.
Agriculture strongly influences the character of the community and local employment, while volunteering, sport and community organisations play an important role in community life.
The Irwin River is the principal river system associated with the Shire of Mingenew. It flows through the agricultural landscape and forms part of a much larger catchment extending from inland areas east of Mullewa to the Indian Ocean near Dongara. The river and its tributaries provide important riparian habitat and contribute to the ecological and landscape values of the Shire. Surface water and groundwater are closely connected in parts of the Mingenew area. Groundwater discharge contributes to sections of the Irwin River and associated waterways, while in other locations river flow contributes recharge to underlying aquifers. Groundwater is an important resource for agriculture, industry, domestic use and groundwater-dependent ecosystems. The Shire includes the Mingenew groundwater-management subarea within the Arrowsmith Groundwater Area of the Northern Perth Basin. Local groundwater resources include the Mingenew–Parmelia aquifer, which supports freshwater springs, wetlands and river ecosystems. Protecting water quality and maintaining sustainable groundwater use are important for both productive land uses and water-dependent ecosystems. Salinity is also an important issue in parts of the Irwin River system, particularly where saline groundwater interacts with the river and its tributaries.
