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's analysis, Winthrop's population is around 6,526 as of Feb 2026. This reflects an increase of 506 people (8.4%) since the 2021 Census, which reported a population of 6,020 people. The change is inferred from the estimated resident population of 6,526 from the ABS as of June 2024 and an additional 4 validated new addresses since the Census date. This population level equates to a density ratio of 1,875 persons per square kilometer, which is above the average seen across national locations assessed by AreaSearch. Winthrop's 8.4% growth since the census positions it within 1.5 percentage points of the national average (9.9%), demonstrating competitive growth fundamentals. Population growth for the area was primarily driven by overseas migration, which contributed approximately 84.6% 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 utilizing 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 we examine future population trends, an above-median population growth of Australian statistical areas is projected, with the area expected to grow by 1,278 persons to 2041 based on the latest annual ERP population numbers, recording a gain of 19.6% in total over the 17 years.

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

Winthrop has averaged around 5 new dwelling approvals each year, totalling 27 homes over the past 5 financial years. So far in FY-26, 1 approval has been recorded. Given an average of 15.6 new residents per year arriving per dwelling constructed over the past 5 financial years (between FY-21 and FY-25), demand significantly exceeds new supply, which usually results in price growth and increased buyer competition, while new properties are constructed at an average value of $486,000, revealing that developers are targeting the premium market segment with higher-end properties.

When measured against Greater Perth, Winthrop has significantly less development activity (86.0% below regional average per person). This constrained new construction usually reinforces demand and pricing for existing dwellings. This is likewise lower than nationally, reflecting market maturity and pointing to possible development constraints. Further, recent building activity consists entirely of detached houses, maintaining the area's traditional suburban character with a focus on family homes appealing to those seeking space. The location has approximately 1344 people per dwelling approval, demonstrating an established market.

Looking ahead, Winthrop is expected to grow by 1,278 residents through to 2041 (from the latest AreaSearch quarterly estimate). At current development rates, housing supply may struggle to match population growth, potentially heightening buyer competition and supporting price increases.

Winthrop has emerging levels of nearby infrastructure activity, ranking in the 34thth percentile nationally

The exceptional employment performance in Winthrop places it among Australia's strongest labour markets

Winthrop has a highly educated workforce, with professional services showing strong representation, an unemployment rate of just 1.5%, and 0.5% in estimated employment growth over the past year. As of December 2025, 3,618 residents are in work while the unemployment rate is 2.6% below Greater Perth's rate of 4.1%, and workforce participation lags significantly (66.4% compared to Greater Perth's 71.9%). Based on Census responses, a low 12.8% of residents were found to work from home, though Covid-19 lockdown impacts should be considered.

Employment among residents is concentrated in health care & social assistance, education & training, and professional & technical services. The area has a particular employment specialization in professional & technical services, with an employment share 1.4 times the regional level. Conversely, construction shows lower representation at 6.2% versus the regional average of 9.3%. The predominantly residential area appears to offer limited employment opportunities locally, as indicated by the count of the Census working population versus the resident population.

Based on AreaSearch analysis of SALM and ABS data, the 12-month period saw employment increasing by 0.5% alongside the labour force increasing by 0.8%, resulting in unemployment rising by 0.3 percentage points. This contrasts with Greater Perth, where employment rose by 2.3%, the labour force grew by 2.6%, and unemployment rose 0.3 percentage points. Jobs and Skills Australia's national employment forecasts from May-25 can offer further insight into potential future demand within Winthrop. These projections, covering five and ten-year periods, have been mapped against the local employment profile to estimate growth patterns. While national employment is forecast to expand by 6.6% over five years and 13.7% over ten years, growth rates differ significantly between industry sectors. Applying these industry-specific projections to Winthrop's employment mix suggests local employment should increase by 6.7% over five years and 13.8% over ten years (please note this is a simple weighting extrapolation for illustrative purposes and does not take into account localised population projections).

Income levels align closely with national averages, indicating typical economic conditions for Australian communities according to AreaSearch analysis

The Winthrop SA2's median income among taxpayers is $48,395 and the average income stands at $74,354, compared to figures for Greater Perth of $60,748 and $80,248 respectively. Based on Wage Price Index growth of 9.62% since FY-23, current estimates would be approximately $53,051 (median) and $81,507 (average) as of September 2025. Census data reveals household incomes rank exceptionally at the 84th percentile ($2,324 weekly), though personal income ranks lower at the 40th percentile. Looking at income distribution, 26.5% of the population (1,729 individuals) fall within the $4000+ income range, differing from patterns across regional levels where $1,500 - 2,999 dominates with 32.0%. The substantial proportion of high earners (40.0% above $3,000/week) indicates strong economic capacity throughout Winthrop. After housing costs, residents retain 89.6% of income, reflecting strong purchasing power, and the area's SEIFA income ranking places it in the 9th decile.
