Winthrop

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

Winthrop's population is estimated at 6,526 as of Feb 2026. This reflects an increase of 506 people since the 2021 Census, which reported a population of 6,020. The change was inferred from AreaSearch's examination of latest ERP data release by ABS (June 2024) and additional validated new addresses since the Census date. This equates to a density ratio of 1,875 persons per square kilometer. Winthrop's population growth since census is 8.4%, within 1.5 percentage points of national average (9.9%). Population growth was primarily driven by overseas migration contributing approximately 85.0% of overall population gains during recent periods.

AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered, growth rates by age cohort provided by ABS in its latest Greater Capital Region projections (released in 2023, based on 2022 data) are used. Population projections indicate an above median growth for statistical areas across the nation. Winthrop is expected to grow by 1,278 persons to 2041, reflecting a gain of 19.6% over the 17 years.

Residential development activity is lower than average in Winthrop according to AreaSearch's national comparison of local real estate markets

AreaSearch analysis of ABS building approval numbers for Winthrop shows an average of around 5 new dwelling approvals per year. Between FY-21 and FY-25, approximately 27 homes were approved, with one more approved in FY-26 so far.

This averages to about 15.6 people moving to the area per year for each dwelling built during these years. Demand significantly exceeds new supply, typically leading to price growth and increased buyer competition. Developers target the premium market segment, with new homes being built at an average expected construction cost of $626,000. Compared to Greater Perth, Winthrop has markedly lower building activity, at 86.0% below the regional average per person. This scarcity of new properties usually strengthens demand and prices for existing properties.

The area's established nature is indicated by its level being under the national average, potentially suggesting planning limitations. Recent development in Winthrop has been entirely comprised of detached houses, preserving the area's suburban nature and attracting space-seeking buyers. With around 1292 people per dwelling approval, Winthrop reflects a highly mature market. According to AreaSearch's latest quarterly estimate, Winthrop is expected to grow by 1,278 residents through to 2041. If current construction levels persist, housing supply could lag population growth, likely intensifying buyer competition and underpinning price growth.

Winthrop has emerging levels of nearby infrastructure activity, ranking in the 36thth percentile nationally
