The population in the shire  has decreased since 2011, representing a total decline of 0.6%.

Estimates of the resident populations as at 30 June are released annually for Local Government Areas (LGAs) in Australia by the Australian Bureau of Statistics. The estimates are generally revised 12 months later and final estimates are available after the following census. Visit the ABS website for further details.

The economy of Perenjori is largely based on broadacre agriculture. Mining in the region is also an important contributor to the economy with emergence of projects including the Karrara Mining and Mount Gibsons Mining Extension Hill (Shire of Perenjori, 2014). Approximately 600 residents are employed in the work force.

Employment by sector (Service related industry, Retail related industry, Agriculture, fishing and forestry, Mining, Manufacturing, Construction, Other) is depicted in the chart below.

The main land uses as shown in the Local Planning Scheme for the Shire of Perenjori includes residential, commercial, rural, industry and mining.

Priority conservation areas includes the Caron Nature Reserve, West Perenjori Nature Reserve, Bowgada Nature Reserve, Weelhamby Lake Nature Reserve, East Latham Nature Reserve and Maya Nature Reserve.

Nature Reserves

Underlying the Shire of Perenjori is south west terrain which forms a part of the Yilgarn Craton. The area comprises of biotite granite and gneiss rocks formed from igneous and metamorphic rocks. Underlying the northern portion of the shire (bordering the Shire of Morawa) is the Youanmi terrrain which forms a part of the Yilgarn craton. The area comprises of rocks rich in magnesium and iron along with layered sills of gabbro and dolerite. The north east portion of shire is under lined by the Youanmi Terrain which forms part of the Yilgarn Craton. The area comprises of iron and magnesium rich rocks, layered sills of gabbro and dolerite and banded iron formations.

The soils underlying the shire consists of deep sandy and loamy earth soils. Saline soils occurring within a shallow water table are commonly associated with the narrow drainage lines and salt lakes in the shire. The remainder of the shire is typically characterised by undulating plains of sand dunes and areas of broad ridge crest with emergent breakaways and open depressions.

Priority Fauna Species

IBRA Regions

  • Tallering sub-IBRA

    The Tallering sub-IBRA forms part of the Yalgoo IBRA. The Yalgoo IBRA is dominated by red sandy plain of low woodlands to open woodlands of Eucalyptus, Acacias and Callitris (Desmond and Chant, 2001d).

  • Ancient Drainage subregion (Avon Wheatbelt 1)

    The Ancient Drainage subregion occurs in the eastern LGAs of the NAR. This subregion is characterised by Proteaceous scrub occupies much of the lateritic hills and outcrops. The alluvial plains associated with the drainage lines is dominated by eucalypts, Casuarinas, York Gum and Jam wattle woodlands (Beecham, 2001a).

Groundwater Areas

  • Gascoyne Groundwater Area

    The Gascoyne Groundwater Area extends north to Kalbarri and bounds the Arrowsmith Groundwater Area east to pastoral country. The largest groundwater aquifer occurs in the Yarragadee Formation, which has an estimated yield of 22.5 million m³/year (NACC, 2005). Groundwater from fractured rock aquifers in the eastern, inland part of the region is predominantly saline and poor yielding. This region of the Gascoyne Groundwater Area falls under the Carnarvon Artesian Basin Allocation Plan.


  • Yarra Yarra and Monger Lakes

    Drainage Basin Length (km) Catchment Area (km2) Average Stream Salinity (mg/L) Key Characteristics
    Yarra-Yarra and Moore-Hill 350 17,700 >35,000 Yarra Yarra Lake is the terminal point for an extensive chain of salt lakes. The major lakes in the system include Nullewa Lake, Weelhamby Lake, Mongers Lake, Lake Goorly, Lake DeCourey and Lake Hillman.Approximately 42 % of the Yarra Yarra Drainage Basin is in the NAR. Due to the basin’s flat terrain, drainage is generally uncoordinated, with each lake having its own internal drainage system. However, in wet years the lakes overflow along a broad drainage line, ending up in Yarra Yarra Lake. It is uncertain if there is a surface or groundwater connection between Yarra Yarra Lake and the Coonderoo River, a tributary of the Moore River.
  • Moore River

    Drainage Basin Length (km) Catchment Area (km2) Average Stream Salinity (mg/L) Key Characteristics
    Moore-Hill 288 13,450 3000-35000 The Moore River’s eastern reaches (Moore River East) which originates near Dalwallinu, and northern reaches (Moore River North) commences east of Coorow. The major tributaries are the Coonderoo River and Gingin Brook. The Moore River enters the ocean at Guilderton and the estuary is only open to the ocean for a few weeks each year.
