Kardinya

An assessment of population growth drivers in Kardinya reveals an overall ranking slightly below national averages considering recent, and medium term trends

Based on analysis of ABS population updates for the broader area, and new addresses validated by AreaSearch, the suburb of Kardinya's population is estimated at around 10,773 as of Feb 2026. This reflects an increase of 1,636 people (17.9%) since the 2021 Census, which reported a population of 9,137 people. The change is inferred from the resident population of 10,584, estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024 and an additional 137 validated new addresses since the Census date. This level of population equates to a density ratio of 2,459 persons per square kilometer, placing it in the upper quartile relative to national locations assessed by AreaSearch. Kardinya's 17.9% growth since the 2021 census exceeded the national average (9.9%), along with the SA3 area, marking it as a growth leader in the region. Population growth for the suburb was primarily driven by overseas migration that contributed approximately 95.0% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with 2022 as the base year. For any SA2 areas not covered by this data, and to estimate growth across all areas in the years post-2032, AreaSearch is utilising the growth rates by age cohort provided by the ABS in its latest Greater Capital Region projections (released in 2023, based on 2022 data). As future population trends are examined, an above median population growth of statistical areas analysed by AreaSearch is projected for the suburb, with an expected increase to 12,151 persons by 2041 based on aggregated SA2-level projections, reflecting a gain of 7.5% in total over the 17 years.

Recent residential development output has been above average within Kardinya when compared nationally

Kardinya averaged approximately 99 new dwelling approvals per year based on AreaSearch analysis. Between FY-21 and FY-25, about 495 homes were approved, with another 19 approved so far in FY-26. This translates to around 1.7 new residents per year per dwelling constructed over the past five financial years, indicating a balanced supply and demand dynamic. However, recent figures suggest an acceleration to 14.3 people per dwelling over the past two financial years, implying increasing demand and tightening supply.

The average construction value of development projects in Kardinya is approximately $401,000, reflecting a focus on premium segment properties. This year alone, there have been $333.1 million in commercial approvals, highlighting significant local commercial activity. Compared to Greater Perth, Kardinya has 64.0% more building activity per person, offering buyers greater choice. However, construction activity has eased recently.

New development primarily consists of standalone homes (94.0%) with townhouses or apartments making up the remaining 6.0%, preserving the area's suburban nature and attracting space-seeking buyers. Kardinya indicates a mature market with around 358 people per approval. According to AreaSearch's latest quarterly estimate, the population is forecasted to grow by 807 residents through to 2041. At current development rates, new housing supply should comfortably meet demand, providing favorable conditions for buyers and potentially supporting growth beyond current population projections.
