AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area released in 2024 with a base year of 2022. For areas not covered and years post-2032, the SA State Government's Regional/LGA projections by age category are adopted, based on 2021 data and released in 2023, adjusted using weighted aggregation from LGA to SA2 levels. Looking ahead, lower quartile growth is anticipated for Australian statistical areas, with Collinswood expected to expand by 40 persons to 2041 based on aggregated SA2-level projections, reflecting a reduction of 0.2% in total over the 17 years.

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

AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, shows Collinswood has experienced around 3 dwellings receiving development approval each year. Over the past 5 financial years, between FY-21 and FY-25, an estimated 16 homes were approved, with a further 4 approved so far in FY-26. Each dwelling built over these years attracted an average of 2.2 new residents per year, indicating solid demand that supports property values.

New homes are being constructed at an average expected cost of $460,000, demonstrating a focus on the premium segment with upmarket properties. In FY-26, $1.2 million in commercial approvals have been registered, reflecting the area's residential nature. Compared to Greater Adelaide, Collinswood shows substantially reduced construction, at 70.0% below the regional average per person. This scarcity of new dwellings typically strengthens demand and prices for existing properties. Nationally, this is lower than the national average, reflecting market maturity and possible development constraints.

All new construction in Collinswood has been comprised of detached dwellings, preserving the area's suburban nature with an emphasis on detached housing attracting space-seeking buyers. Notably, developers are constructing more detached housing than the existing pattern implies, at 47.0% higher than the Census figure, reflecting persistent strong demand for family homes amid densification trends. With around 432 people per approval, Collinswood indicates a mature market with stable or declining population expected in the future, potentially reducing pressure on housing and creating opportunities for buyers.
