Collinswood

Population growth drivers in Collinswood are slightly above average based on AreaSearch's ranking of recent, and medium term trends

As of May 2026, the estimated population of the suburb of Collinswood is around 1,537 people. This represents an increase of 41 individuals since the 2021 Census, which recorded a population of 1,496 people. The latest estimate is based on AreaSearch's validation of new addresses following the examination of the ABS's ERP data release in June 2025. This increase results in a population density ratio of approximately 2,955 persons per square kilometer, placing Collinswood in the upper quartile relative to other locations assessed by AreaSearch. The primary driver for this growth was overseas migration, contributing about 72.0% of overall population gains during recent periods.

AreaSearch employs 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 years post-2032, the SA State Government's Regional/LGA projections by age category are adopted, based on 2021 data released in 2023, with adjustments made using a method of weighted aggregation of population growth from LGA to SA2 levels. Looking ahead, lower quartile growth is anticipated for statistical areas across the nation. Based on aggregated SA2-level projections, Collinswood's population is expected to expand by 43 persons to reach 1,580 people by 2041, reflecting an increase of approximately 2.8% over the 16-year period.

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

Collinswood has seen approximately 3 dwelling approvals per year over the past 5 financial years, totalling around 16 homes. In FY26 so far, 7 approvals have been recorded. On average, about 3.9 people move to the area annually for each new dwelling built between FY21 and FY25. This outpaces supply, potentially increasing competition among buyers and upward pressure on prices.

The average construction cost of new homes is around $460,000, indicating a focus on premium properties. Commercial approvals in FY26 totalled $1.2 million, suggesting minimal commercial development activity. Compared to Greater Adelaide, Collinswood has significantly reduced construction levels (70.0% below the regional average per person), which may strengthen demand and prices for existing properties. This activity is also below national averages, possibly due to the area's maturity or planning constraints. All recent building activity consists of standalone homes, maintaining the area's suburban character with a focus on family homes.

Interestingly, developers are building more traditional houses than current market mix suggests (47.0% at Census), indicating strong demand for family homes despite density pressures. With around 435 people per dwelling approval, Collinswood shows signs of a developed market. Population forecasts suggest the area will gain 43 residents by 2041, with current development rates comfortably meeting demand and providing good conditions for buyers, potentially supporting growth beyond current projections.
