Wallacia

Population growth drivers in Wallacia are above average based on AreaSearch's ranking of recent, and medium to long-term trends

Wallacia's population is estimated at around 1,825 as of Feb 2026. This reflects an increase of 114 people since the 2021 Census, which reported a population of 1,711 people. The change is inferred from the resident population of 1,721 estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024 and address validation since the Census date. This level of population equates to a density ratio of 71 persons per square kilometer. Wallacia's 6.7% growth since the 2021 census exceeded the SA4 region's 6.5%, marking it as a growth leader in the region. Population growth was primarily driven by interstate migration contributing approximately 41.0% of overall population gains during recent periods, although all drivers including natural growth and overseas migration were positive factors.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, released in 2024 with 2022 as the base year. For areas not covered by this data, AreaSearch utilises NSW State Government's SA2 level projections released in 2022 with 2021 as the base year. Growth rates by age group are applied to all areas for years 2032 to 2041. Exceptional growth is predicted over the period, placing Wallacia in the top 10 percent of national statistical areas. The suburb is expected to grow by 1,764 persons to 2041 based on aggregated SA2-level projections, reflecting an increase of 91.0% in total over the 17 years.

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

AreaSearch analysis of ABS building approval numbers shows Wallacia has received around 2 dwelling approvals annually over the past 5 financial years, totalling an estimated 14 homes. No approvals have been recorded so far in FY-26. On average, 20.2 people moved to the area for each dwelling built between FY-21 and FY-25, indicating demand significantly exceeds new supply. New dwellings are developed at an average cost of $572,000, suggesting a focus on premium properties.

This financial year has seen $1.5 million in commercial development approvals, predominantly residential. Compared to Greater Sydney, Wallacia has 73.0% less development activity per person. The area's constrained new construction reinforces demand and pricing for existing dwellings. This activity is also below national average, reflecting the area's maturity and possible planning constraints. New development consists of 50.0% standalone homes and 50.0% townhouses or apartments, marking a shift from existing housing patterns (currently 86.0% houses). The estimated population per dwelling approval is 1253 people. By 2041, Wallacia is expected to grow by 1,660 residents.

If current construction levels persist, housing supply may lag population growth, potentially intensifying buyer competition and price growth.
