This analysis uses ABS Statistical Areas Level 2 (SA2) boundaries, which can materially differ from Suburbs and Localities (SAL) even when sharing similar names.
SA2 boundaries are defined by the Australian Bureau of Statistics and are designed to represent communities for statistical reporting (e.g., census and ERP).
Suburbs and Localities (SAL) represent commonly-used suburb/locality names (postal-style areas) and may use different geographic boundaries. For comprehensive analysis, consider reviewing both boundary types if available.

Sales Detail
Kojonup has an estimated 4,276 residents, up from 4,053 at the 2021 Census — a change of 223 people, or 5.5%. Overseas migration accounts for 79.4% of that increase. Fewer than ten people live on each square kilometre, across a boundary that takes in surrounding rural land. Population is estimated from ABS Estimated Resident Population releases and GNAF address data, re-based from the 2021 Census and updated annually.
Detail
According to research conducted by AreaSearch, the population of Kojonup stands at roughly 4,276 as of Aug 2026. This represents an addition of 223 people (5.5%) compared to the 4,053 people recorded in the 2021 Census. This adjustment stems from an ABS estimated resident population figure of 4,269 as of June 2025 alongside 26 validated new addresses documented following the Census. The local population density calculates to 0.50 persons per square kilometer, ensuring a spacious residential setting. Growth across the locality has been steered mainly by overseas migration, which made up around 79.4% of total population increases throughout recent times.
Projections published in 2024 (anchored to a 2022 baseline) by ABS/Geoscience Australia for SA2 zones are applied by AreaSearch. Where SA2 data is unavailable, as well as for all post-2032 regional forecasts, AreaSearch integrates age-bracket growth metrics from the ABS Greater Capital Region projections (published in 2023 using 2022 figures). Looking forward, population expansion is anticipated to sit slightly beneath the non-metropolitan national median, with the locality projected to gain 399 persons to 2041 under latest annual ERP figures, constituting an overall rise of 9.2% across the 16 years.
Frequently Asked Questions - Population
41 new dwellings have been approved in Kojonup over the past five years, an average of 8 a year. That is 1.9 approvals per 1,000 residents. Figures come from ABS building approvals aggregated to this SA2 boundary and are updated monthly as the ABS releases them.
Detail
Residential building approvals in Kojonup have averaged around 8 dwellings annually, totaling 41 homes sanctioned over the preceding 5 financial years (between FY-22 and FY-26). Over this identical timeframe of 5 financial years (between FY-22 and FY-26), the region gained an average of 2.1 new residents per constructed dwelling, demonstrating consistent underlying demand that underpins asset values. The average construction cost for these new dwellings is $335,000, which is lower than the wider region and highlights relatively affordable building opportunities. Concurrently, commercial planning permits amounted to $2.9 million this financial year, reflecting a restrained commercial building pipeline.
Development throughput in Kojonup lags substantially behind Rest of WA, registering at 63.0% below regional average per person. Although building work has picked up lately, the subdued volume of new construction generally reinforces demand and pricing for existing housing stock. Activity also tracks below the broader country, pointing to an established community context and potential planning restrictions. Recent residential building permits have been made up exclusively of standalone houses, preserving low-density surroundings that appeal to buyers prioritizing space. A metric of 389 people per residential approval underscores this subdued construction climate. Forecasts indicate that Kojonup will add 392 residents through to 2041 (utilizing the most recent AreaSearch quarterly update). With construction progressing at its present pace, the supply of new dwellings could fall short of demographic growth, which may heighten competition among purchasers and place upward pressure on values.

Frequently Asked Questions - Infrastructure
Katanning to Kojonup Pipeline Replacement
Replacement of 2.2 kilometres of a 60-year-old pipeline section between Katanning and Kojonup to enhance water supply security and reliability for over 530 homes and businesses in Kojonup and farmland in the Great Southern region. The project was jointly funded by the Federal and WA Governments through the National Water Grid Fund and delivered by Water Corporation and Benang Energy.
Katanning Energy Project
Community-led renewable energy initiative by Katanning Energy Pty Ltd providing tailored solar energy and battery solutions for local residents and businesses. The project aims to establish a localised micro-grid with intra-community trading and transition all 1,465 sites within the town boundary.
Katanning Supertown Heritage Centre Project
A comprehensive community development initiative in Katanning, WA, aimed at fostering growth and amenity. The project includes the Master Plan, the Welcome Precinct (All Ages Playground and Changing Places facility), Town Centre revitalisation (Cultural Precinct/Austral Terrace), Piesse Lake Residential Sub-Division, and Piesse Lake Park. Components like the Welcome Precinct, the KAARL Yarning Place, and the Shire Administration/Civic Building are completed.
Piesse Lake Structure Plan and Residential Development
The Piesse Lake Structure Plan, approved by the WAPC, provides a framework for medium-density residential and aged persons accommodation. The 17.7 hectare site encompasses approximately 50 residential lots, an aged and dependent persons site, and nearly 11 hectares of public open space centered around the revitalised Piesse Park and Lake.
Katanning Industrial Expansion Structure Plan (SPN/2029)
The Katanning Industrial Expansion Structure Plan (SPN/2029) is an approved structure plan that provides the statutory framework for staged industrial development east of the Katanning townsite. The precinct is intended to support industrial expansion associated with the Katanning Regional Sheep Saleyards and existing rural service industries. The structure plan remains operative and available through the Shire of Katanning and WA Government planning portals, with development expected to occur progressively as demand and subdivision proposals arise.
Katanning Aerodrome Runway Restoration
Restoration and resealing of the runway at Katanning Aerodrome, funded through a $236,817 grant under Round 4 of the Australian Government's Regional Airports Program. The works will improve all-weather safety and accessibility for critical services relying on the aerodrome, including Royal Flying Doctor Service medical evacuations, fire-fighting aircraft and emergency service operations, benefiting the wider Great Southern farming community.
Ambrosia Wind Farm
The Ambrosia Wind Farm is a proposed 600MW onshore wind energy project located near Moodiarrup, approximately 55km south-east of Collie and 30km south of Darkan within the Shire of West Arthur. Being developed by Green Wind Renewables in partnership with Aula Energy (Macquarie Group's onshore renewables business), the project will host up to 100 wind turbines and is expected to generate around 1.8 terawatt-hours annually, enough to power approximately 300,000 Western Australian homes and offset around 1 million tonnes of CO2 each year.Once built, it would be one of the largest wind farms in Western Australia and would connect into the South-West Interconnected System (SWIS). The project remains in the Early Development phase as of 2026, with a 150m meteorological mast installed and operational to gather wind resource data. Community drop-in sessions were held at Moodiarrup and Darkan in February 2025, and the project is expected to progress to the Late Development phase in 2027. Estimated construction will support around 300 jobs, with around 20 permanent operational roles. Ambrosia is the first of four projects (alongside Grevillea, Wandoo and Banksia) being developed under the Green Wind / Aula partnership totalling up to 2.4GW.
Lake Towerrinning Upgrade Project
Upgrade funded under the Australian Government LRCI Round 3 to extend the public boat ramp, add an all-access boardwalk and accessible ramp to the BBQ area, and convert the old change rooms to all-weather seating. Works complement earlier jetty refurbishment and playground/shade upgrades, improving universal access and visitor amenity at this key recreation lake.
2,255 residents of Kojonup are employed, from a labour force of 2,330. Unemployment sits at 3.2%, with participation at 67.8%. Weighted for its industry mix, the area's sectors are forecast to grow about 4.1% nationally over five years. That reflects industry composition only and makes no allowance for local population growth. Unemployment and labour force come from ABS Small Area Labour Markets, updated quarterly; the industry and occupation profile is from the 2021 Census.
Detail
The workforce in Kojonup is well-skilled and spread across diverse sectors, maintaining an unemployment rate of just 3.2%. There were 2,255 working residents as of March 2026, with local unemployment tracking 0.3% below the Regional WA level of 3.5%. Participation in the labour force remains standard at 67.8% (versus 65.4% in Regional WA). Census records indicated that 22.1% of employed locals conducted their work from home, a figure that may reflect pandemic lockdown circumstances. The primary sectors providing jobs for local residents are agriculture, forestry & fishing, education & training, along with health care & social assistance.
The community demonstrates a notable concentration in agriculture, forestry & fishing, where its proportion of employment reaches 5.6 times the regional level. Conversely, mining accounts for only 0.9% of the local workforce, contrasting with 11.7% in Regional WA. A comparison of resident worker tallies from the Census against local population totals suggests that numerous inhabitants travel outside the area for employment. SALM and ABS records analyzed by AreaSearch indicate that over the 12 months to March 2026, the local workforce contracted by 5.2% while employment dropped by 7.0%, pushing the jobless rate up by 1.9 percentage points. Across Regional WA over the same span, employment decreased by 0.1%, the workforce expanded by 0.3%, and unemployment ticked up by 0.4 percentage points. National employment modeling from Jobs and Skills Australia as of Mar-26 provides broader context on future hiring demand. Over five years, nationwide employment is modeled to rise 6.6% and over ten years by 13.7%, though trajectories vary by industry. Aligning these sector projections with the local economic structure indicates Kojonup employment may grow by 4.1% over five years and 9.9% over ten years (representing a baseline weighted illustration that excludes localized demographic projections).

How the numbers are built
Population
The Census provides the small-area baseline, aggregated from mesh blocks to this boundary. It is then re-based to the ABS Estimated Resident Population (June 2025 release), and new dwellings built since Census night are counted from address data — 26 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (4,053 at the 2021 Census → 4,276 now). Annual growth rates are compound (CAGR), not simple averages.
Age profile
Cohort shares are not raw Census counts. Every cohort is held as a pair — the Census baseline and a current estimate — and the split is re-based using ERP and state population projections, current to Aug 2026. Median age is the Census median plus modelled change since. Charts that show both are labelled "2021 Census vs Current Estimate".
Property sales
Sourced from the state valuation authority's sales register — current, not Census, and refreshed weekly. Medians are calculated from settled transactions in the period shown; periods with very low transaction counts are flagged or suppressed, because a handful of sales can move a median substantially.
Rents
Derived from state rental bond lodgement data, by dwelling type and bedroom count. Bonds are lodged at the start of a new tenancy, so this reflects new lettings, not the whole rented stock.
Development & infrastructure
Building approvals come from current ABS releases; development applications are collected from council and state planning portals; the infrastructure pipeline is compiled from Infrastructure Australia and local government sources. Applications are matched to this boundary by address or coordinates, so very recent lodgements may not yet appear.
Employment & income
Industry and occupation structure comes from the Census, but the headline labour-market indicators do not. Unemployment and labour force are derived from ABS Small Area Labour Markets (quarterly). The employment outlook applies Department of Employment forecasts for all 19 industry divisions to this area's own industry mix (the agency is now Jobs and Skills Australia), as does the Internet Vacancy Index used for job demand. Because it is weighted on industry composition alone, that outlook carries no allowance for local population growth — in fast-growing areas the real rise in local jobs will typically be higher. Income combines Census household income with ATO taxable-income statistics for FY 2023, indexed forward using the Wage Price Index.
Education, transport & amenities
School enrolments, ICSEA and performance come from ACARA's current release, not the Census. Public transport stops and service frequency are derived from GTFS timetable feeds published by state transport departments. Services and amenities are proximity and count scores built from provider directories, refreshed on their own cycle. The Census contributes only the travel-to-work and qualification measures.
Rankings and benchmarks. Where we rank this area, the comparison set is every area of the same boundary type — suburbs against suburbs, SA2s against SA2s. Benchmarks compare this area against its greater capital city region and the national figure for the same measure and period.
Limits worth knowing. Small areas carry larger error margins, and the ABS introduces small random adjustments to Census counts to protect confidentiality — so totals may not sum exactly. Estimates re-based from regional data describe the area's expected trajectory, not a direct count of it. Figures are indicative for research and are not financial, planning or valuation advice.
