This analysis uses Suburbs and Localities (SAL) boundaries, which can materially differ from Statistical Areas (SA2) even when sharing the same name.
SAL boundaries are defined by Australia Post and the Australian Bureau of Statistics to represent commonly-known suburb names used in postal addresses.
Statistical Areas (SA2) are designed for census data collection and may combine multiple suburbs or use different geographic boundaries. For comprehensive analysis, consider reviewing both boundary types if available.

Population
Population growth drivers in Windsor Gardens are strong compared to national averages based on AreaSearch's ranking of recent, and medium to long-term trends
As per AreaSearch's analysis of ABS population updates for the broader area, the estimated population of the suburb of Windsor Gardens was approximately 5,854 as of May 2026. This figure represents an increase of 27 people from the previous count of 5,827 recorded in the 2021 Census, marking a growth rate of 0.5%. The latest estimated resident population (ERP) data release by the ABS in June 2025, along with AreaSearch's validation of new addresses since the Census date, contributed to this increase. This results in a population density ratio of 2,323 persons per square kilometer for Windsor Gardens, which is higher than the average seen across national locations assessed by AreaSearch. Overseas migration was the primary driver behind this population growth, accounting for approximately 74.0% of overall population gains during recent periods.
AreaSearch's projections for the suburb of Windsor Gardens are based on ABS/Geoscience Australia projections released in 2024, with a base year of 2022 for each SA2 area. For areas not covered by this data and years post-2032, AreaSearch adopts the SA State Government's Regional/LGA projections by age category, released in 2023 and based on 2021 data, with adjustments made using a method of weighted aggregation of population growth from LGA to SA2 levels. Considering these projected demographic shifts, the suburb of Windsor Gardens is expected to experience a population increase just below the median of national areas by 2041. According to aggregated SA2-level projections, the area is anticipated to gain an additional 696 persons over this period, reflecting an overall increase of 11.8%.

Development
Recent residential development output has been above average within Windsor Gardens when compared nationally
Based on AreaSearch analysis using ABS building approval numbers from statistical area data, Windsor Gardens averaged approximately 55 new dwelling approvals per year. Between FY-21 and FY-25, around 275 homes were approved, with an additional 36 approved so far in FY-26. On average, about 1.1 people moved to the area annually for each dwelling built between FY-21 and FY-25, indicating balanced supply and demand dynamics.
The average expected construction cost of new homes over this period was $379,000, suggesting a focus on premium market developments. This financial year has seen $5.9 million in commercial development approvals, reflecting limited commercial development activity. Compared to Greater Adelaide, Windsor Gardens maintains similar construction rates per person, supporting regional market stability despite recent slowdowns in building activity.
New developments consist of 92.0% detached dwellings and 8.0% medium and high-density housing, preserving the area's suburban character with an emphasis on detached housing attracting space-seeking buyers. With around 167 people per approval, Windsor Gardens reflects a low density area. According to AreaSearch's latest quarterly estimate, Windsor Gardens is projected to add approximately 693 residents by 2041. Given current construction levels, housing supply should meet demand adequately, creating favourable conditions for buyers while potentially enabling growth that exceeds current forecasts.
