Winthrop

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

Based on AreaSearch analysis of ABS population updates and new addresses validated since the 2021 Census, Winthrop's estimated population is around 6,526 as of Nov 2025. This reflects an increase of 506 people (8.4%) compared to the 2021 Census figure of 6,020. The change was inferred from AreaSearch's resident population estimate of 6,526 following examination of ABS's latest ERP data release in June 2024 and four additional validated new addresses since the Census date. This results in a density ratio of 1,875 persons per square kilometer, above national averages assessed by AreaSearch. Winthrop's population growth rate of 8.4% since the census is within 1.3 percentage points of the national average (9.7%). Overseas migration contributed 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 by this data and post-2032 growth estimates, AreaSearch utilises growth rates by age cohort provided by the ABS in its latest Greater Capital Region projections (released in 2023, based on 2022 data). Future population trends project an above median growth for Australian statistical areas. The Winthrop SA2 is expected to increase by 1,278 persons to 2041, reflecting a gain of 19.6% over the 17-year period.

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 approximately 5 new homes approved annually. Between Financial Year 21 (FY-21) and FY-25, around 27 homes were approved, with one so far in FY-26.

This results in about 15.6 people moving to the area per year for each dwelling built over these five years. Demand significantly exceeds new supply, typically leading to price growth and increased buyer competition. New homes are constructed at an average value of $626,000, indicating developers target the premium market segment with higher-end properties. Compared to Greater Perth, Winthrop has markedly lower building activity, 86.0% below the regional average per person. This scarcity strengthens demand and prices for existing properties.

Recent development consists entirely of detached houses, preserving Winthrop's suburban nature and attracting space-seeking buyers. With around 1292 people per dwelling approval, Winthrop reflects a highly mature market. By 2041, Winthrop is expected to grow by 1,278 residents. If current construction levels persist, housing supply may lag population growth, intensifying buyer competition and underpinning price growth.
