Wallacia

Population growth drivers in Wallacia are strong compared to national averages based on AreaSearch's ranking of recent, and medium to long-term trends

As of November 2025, the estimated population of Wallacia is around 1,763 people. This reflects an increase of 52 individuals since the 2021 Census, which reported a population of 1,711 people. The current figure is inferred from AreaSearch's resident population estimate of 1,718, based on their examination of the latest ERP data release by the ABS in June 2024 and address validation since the Census date. This results in a density ratio of 69 persons per square kilometer in Wallacia. Over the past decade, from 2015 to 2025, the suburb has demonstrated resilient growth patterns with a compound annual growth rate of 4.0%, outpacing its SA3 area. Population growth was primarily driven by interstate migration, contributing approximately 41.0% of overall population gains during recent periods.

However, 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 a base year of 2022, for areas covered by this data. For areas not covered, they utilise the NSW State Government's SA2 level projections, released in 2022 with a base year of 2021. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. Future population trends predict exceptional growth, placing Wallacia in the top 10 percent of national statistical areas. By 2041, the suburb is expected to grow by 1,946 persons based on aggregated SA2-level projections, reflecting an increase of 118.6% over the 17-year period from 2024 to 2041.

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 indicates Wallacia has received approximately 2 dwelling approvals annually over the past 5 financial years from FY-21 to FY-25. This totals around 10 homes. In FY-26 so far, no approvals have been recorded.

Each dwelling built attracted an average of 28 people per year to the area during this period. The demand for housing significantly exceeds new supply, which typically leads to price growth and increased buyer competition. New dwellings are developed at an average construction cost value of $572,000. Compared to Greater Sydney, Wallacia has significantly less development activity, 81.0% below the regional average per person. This constrained new construction usually reinforces demand and pricing for existing dwellings.

Nationally, development activity is also lower, reflecting market maturity and possible development constraints. Recent building activity in Wallacia consists entirely of detached dwellings, maintaining the area's traditional low density character with a focus on family homes appealing to those seeking space. The estimated population per dwelling approval is 937 people. Population forecasts indicate Wallacia will gain approximately 2,091 residents by 2041, according to AreaSearch's latest quarterly estimate. At current development rates, housing supply may struggle to match population growth, potentially heightening buyer competition and supporting price increases.

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

Key employment sectors include construction, health care & social assistance, and manufacturing. Construction stands out with a share of employment 2.5 times the regional average.

Conversely, professional & technical services have lower representation at 4.1% compared to the regional average of 11.5%. The area may lack local employment opportunities as indicated by Census data. Over June 2024 to June 2025, labour force levels decreased by 2.6%, alongside a 2.6% employment decline, keeping unemployment relatively stable at 1.8%. Meanwhile, Greater Sydney saw employment growth of 2.6% and labour force growth of 2.9%, with unemployment rising slightly to 4.5%. Jobs and Skills Australia's national employment forecasts from Sep-2022 project overall employment growth of 6.6% over five years and 13.7% over ten years. Applying these projections to Wallacia's employment mix suggests local employment should increase by 5.8% over five years and 12.1% over ten years, though this is a simple weighting extrapolation for illustrative purposes only.
