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.

Sales Detail
Wallacia has an estimated 1,687 residents. The population has thinned by an average 1.2% a year over five years, slower than 96% of areas nationally. Density is about 66 people per square kilometre. Population is estimated from ABS Estimated Resident Population releases and GNAF address data, re-based from the 2021 Census and updated annually.
Detail
In the suburb of Wallacia, the population is estimated at approximately 1,687 as of May 2026, according to analysis of ABS population updates and address records validated by AreaSearch. This represents a reduction of 24 residents (1.4%) relative to the 1,711 people documented in the 2021 Census. This adjustment is based on a resident population of 1,625, estimated by AreaSearch using the ABS Estimated Resident Population release from June 2025 alongside subsequent address confirmations. Such population figures result in a density of 66 persons per square kilometer, indicating low density and capacity for potential expansion.
Interstate migration was the primary driver of population growth, representing approximately 41.0% of total gains, though all growth categories, including natural increases and overseas arrivals, remained positive. Projections for each SA2 region are based on 2024 ABS and Geoscience Australia releases, using 2022 as the base year, supplemented by 2022 NSW State Government SA2 projections with a 2021 base year where necessary. Age cohort growth rates from these projections are applied to the years 2032 through 2041. Future demographic forecasts suggest the area will experience rapid expansion, ranking in the top 10 percent of statistical areas nationwide. Aggregated SA2 projections indicate an increase of 1,589 residents to 2041, representing a total population growth of 90.5% over the 16 years.
Frequently Asked Questions - Population
Detail
Wallacia has averaged approximately 1 building approval for new dwellings per year, with a total of 6 homes approved during the 5 financial years from FY-21 to FY-25, and none registered during FY-26, according to AreaSearch analysis of ABS data. Because of the local population decrease, the housing supply has kept pace with demand, resulting in a balanced market with choices for buyers. Commercial approvals for the current financial year total $1.5 million, reflecting low commercial construction activity. Building activity in Wallacia is significantly lower than the Greater Sydney average, sitting at 88.0% below the regional per capita rate.
This limited rate of construction tends to support value and demand for existing houses. The level of activity also falls below the national average, indicating a mature market and potential development limitations. Furthermore, recent construction has consisted entirely of detached homes, maintaining the low-density character of the neighborhood which appeals to buyers looking for larger properties. Long-term forecasts suggest the suburb of Wallacia will gain 1,527 residents by 2041, based on the latest quarterly calculations from AreaSearch. If development continues at its current pace, housing construction may not keep up with population growth, which could increase competition among buyers and support upward pressure on prices.

863 residents of Wallacia are employed, from a labour force of 880. Unemployment sits at 1.9%, with participation at 66.4%. Weighted for its industry mix, the area's sectors are forecast to grow about 5.8% nationally over five years. That reflects industry composition only and makes no allowance for local population growth. Unemployment and labour force come from ABS Small Area Labour Markets, updated quarterly; the industry and occupation profile is from the 2021 Census.
Detail
The workforce in Wallacia features a mix of white-collar and blue-collar workers, with construction representing a major employment sector, and a low unemployment rate of 1.9%, based on aggregated statistical area data from AreaSearch. As of March 2026, there are 863 employed residents. The unemployment rate is 2.2% lower than the Greater Sydney level of 4.1%, while workforce participation is slightly lower than the regional average, at 66.4% compared to 69.1% for Greater Sydney. Census data indicates that 33.0% of working residents operated from home, though this figure may reflect the influence of pandemic lockdowns.
The primary employment sectors for local residents are construction, health care & social assistance, and manufacturing. The local representation in construction is highly concentrated, with an employment share that is 2.5 times the Greater Sydney average. Conversely, professional & technical services account for only 4.1% of the workforce, which is below the 11.5% average for Greater Sydney. The relationship between the working population and resident population at the Census suggests a limited volume of local jobs. AreaSearch analysis of SALM and ABS data shows that during the year leading to March 2026, the local labour force contracted by 8.5% and total employment fell by 8.5%, while unemployment levels remained virtually unchanged. This contrasts with Greater Sydney, which recorded employment growth of 1.9% and labour force expansion of 1.9%, alongside a slight decline in unemployment. Future employment trends can be examined using the national forecasts from Jobs and Skills Australia released in May-25, which have been mapped to local employment sectors. While nationwide employment is projected to grow by 6.6% over five years and 13.7% over ten years, trends vary widely by industry. Based on these sectoral projections, local employment in Wallacia is estimated to rise by 5.8% over five years and 12.1% over ten years, representing a basic weighted extrapolation.

How the numbers are built
Population
The Census provides the small-area baseline, aggregated from mesh blocks to this boundary. It is then re-based to the ABS Estimated Resident Population (June 2025 release), and new dwellings built since Census night are counted from address data. The headline figure is therefore a current estimate for May 2026, not a 2021 count (1,711 at the 2021 Census → 1,687 now). Annual growth rates are compound (CAGR), not simple averages.
Age profile
Cohort shares are not raw Census counts. Every cohort is held as a pair — the Census baseline and a current estimate — and the split is re-based using ERP and state population projections, current to May 2026. Median age is the Census median plus modelled change since. Charts that show both are labelled "2021 Census vs Current Estimate".
Property sales
Sourced from the state valuation authority's sales register — current, not Census, and refreshed weekly. Medians are calculated from settled transactions in the period shown; periods with very low transaction counts are flagged or suppressed, because a handful of sales can move a median substantially.
Rents
Derived from state rental bond lodgement data, by dwelling type and bedroom count. Bonds are lodged at the start of a new tenancy, so this reflects new lettings, not the whole rented stock.
Development & infrastructure
Building approvals come from current ABS releases; development applications are collected from council and state planning portals; the infrastructure pipeline is compiled from Infrastructure Australia and local government sources. Applications are matched to this boundary by address or coordinates, so very recent lodgements may not yet appear.
Employment & income
Industry and occupation structure comes from the Census, but the headline labour-market indicators do not. Unemployment and labour force are derived from ABS Small Area Labour Markets (quarterly). The employment outlook applies Department of Employment forecasts for all 19 industry divisions to this area's own industry mix (the agency is now Jobs and Skills Australia), as does the Internet Vacancy Index used for job demand. Because it is weighted on industry composition alone, that outlook carries no allowance for local population growth — in fast-growing areas the real rise in local jobs will typically be higher. Income combines Census household income with ATO taxable-income statistics for FY 2023, indexed forward using the Wage Price Index.
Education, transport & amenities
School enrolments, ICSEA and performance come from ACARA's current release, not the Census. Public transport stops and service frequency are derived from GTFS timetable feeds published by state transport departments. Services and amenities are proximity and count scores built from provider directories, refreshed on their own cycle. The Census contributes only the travel-to-work and qualification measures.
Rankings and benchmarks. Where we rank this area, the comparison set is every area of the same boundary type — suburbs against suburbs, SA2s against SA2s. Benchmarks compare this area against its greater capital city region and the national figure for the same measure and period.
Limits worth knowing. Small areas carry larger error margins, and the ABS introduces small random adjustments to Census counts to protect confidentiality — so totals may not sum exactly. Estimates re-based from regional data describe the area's expected trajectory, not a direct count of it. Figures are indicative for research and are not financial, planning or valuation advice.
