Wallacia

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

The estimated population of the suburb of Wallacia is around 1,687 as of May 2026. This reflects a decrease since the 2021 Census, which reported a population of 1,711 people. The current resident population estimate is 1,625, based on AreaSearch's examination of the latest ERP data release by the ABS in June 2025 and address validation since the Census date. This results in a population density ratio of 66 persons per square kilometer. Population growth was primarily driven by interstate migration, contributing approximately 41.0% of overall population gains during recent periods.

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, NSW State Government's SA2 level projections, released in 2022 with 2021 as the base year, are utilized. Exceptional growth is predicted over the period to 2041, with the suburb expected to grow by 1,589 persons, reflecting an increase of 90.5% in total over the 16 years.

The level of residential development activity in Wallacia is very low in comparison to the average area assessed nationally by AreaSearch

AreaSearch analysis of ABS building approval numbers shows Wallacia had around 2 dwellings receiving development approval annually over the past 5 financial years, totalling an estimated 14 homes. In FY-26 so far, 2 approvals have been recorded. The population has declined recently, but housing supply has remained adequate relative to demand, creating a balanced market with good buyer choice. New dwellings are developed at an average cost of $572,000, indicating a focus on the premium segment.

Additionally, $1.5 million in commercial development approvals have been recorded this financial year, suggesting a predominantly residential focus. Compared to Greater Sydney, Wallacia has significantly less development activity (72.0% below regional average per person), which usually reinforces demand and pricing for existing dwellings. This activity is also below average nationally, 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 significant departure from existing housing patterns (currently 86.0% houses). The estimated count of 1148 people in the area per dwelling approval reflects its quiet, low activity development environment. Looking ahead, Wallacia is expected to grow by 1,527 residents through to 2041, according to the latest AreaSearch quarterly estimate. Should current construction levels persist, housing supply could lag population growth, likely intensifying buyer competition and underpinning price growth.

AreaSearch analysis reveals Wallacia significantly outperforming the majority of regions assessed nationwide

Wallacia has a balanced workforce with representation across white and blue collar jobs, notably in construction. Its unemployment rate was 1.8% as of an AreaSearch aggregation of statistical area data. By December 2025862 residents were employed, with an unemployment rate of 2.3%, below Greater Sydney's 4.2%.

Workforce participation was lower at 66.2% compared to Greater Sydney's 68.8%. Census responses showed 33.0% worked from home, potentially influenced by Covid-19 lockdowns. Dominant sectors included construction, health care & social assistance, and manufacturing. Construction had a particularly high share of employment, at 2.5 times the regional level.

However, professional & technical services were under-represented at 4.1%, compared to Greater Sydney's 11.5%. Locally, employment opportunities appeared limited based on Census data comparing working population to resident population. Between December 2024 and December 2025, labour force levels decreased by 9.3% and employment by 9.2%, leading to a fall in unemployment rate by 0.1 percentage points. In contrast, Greater Sydney saw employment grow by 2.2%. Jobs and Skills Australia's national employment forecasts from May-25 project overall growth of 6.6% over five years and 13.7% over ten years. Applying these projections to Wallacia's employment mix suggests local employment could increase by 5.8% over five years and 12.1% over ten years, though this is a simplified extrapolation for illustrative purposes only.
