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
Walkley Heights is positioned among the lower quartile of areas assessed nationally for population growth based on AreaSearch's assessment of recent, and medium term trends
The estimated population of the suburb of Walkley Heights is around 3,556 as of May 2026. This figure reflects an increase of 43 people since the 2021 Census, which reported a population of 3,513. The current resident population estimate by AreaSearch, based on examination of the latest ERP data release by the ABS in June 2025 and address validation since the Census date, is 3,547. This results in a population density ratio of 2,181 persons per square kilometer, higher than the average seen across national locations assessed by AreaSearch. The primary driver of population growth in Walkley Heights has been overseas migration.
AreaSearch uses 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, released in 2023 based on 2021 data, with adjustments made using weighted aggregation methods from LGA to SA2 levels. Future population dynamics anticipate a growth just below the median of statistical areas across the nation, with Walkley Heights expected to grow by 357 persons to reach 4,961 by 2041 based on aggregated SA2-level projections, reflecting an increase of approximately 9.8% over the 16-year period.

Development
The level of residential development activity in Walkley Heights is very low in comparison to the average area assessed nationally by AreaSearch
AreaSearch analysis of ABS building approval numbers allocated from statistical area data shows Walkley Heights had approximately 2 new homes approved annually over the past 5 financial years, totalling an estimated 13 homes. As of FY-26, 4 approvals have been recorded. The area has experienced population decline, but housing supply remains adequate relative to demand, resulting in a balanced market with good buyer choice. New properties are constructed at an average value of $333,000.
In the current financial year, $3,000 in commercial development approvals have been recorded, indicating a predominantly residential focus. Recent development has consisted entirely of detached houses, preserving Walkley Heights' suburban nature and attracting space-seeking buyers.
Interestingly, developers are building more traditional houses than the Census mix suggests (81.0%), reflecting strong demand for family homes despite density pressures. With around 591 people per dwelling approval, Walkley Heights reflects a mature market. According to AreaSearch's latest quarterly estimate, the area is expected to grow by 348 residents through to 2041. At current development rates, housing supply may struggle to match population growth, potentially increasing buyer competition and supporting price increases.
