Detail
As of Aug 2026, the suburb of Dundas Valley has an estimated population of approximately 5,838, determined through AreaSearch's evaluation of broader regional ABS updates alongside 44 validated new addresses recorded since the Census date. This represents a reduction of 37 people (0.6%) compared to the 2021 Census count of 5,875 people, and follows AreaSearch's resident population estimate of 5,814 derived from the ABS ERP figures released in June 2025. With a population density of 3,225 persons per square kilometer, the suburb ranks in the upper quartile of locations evaluated nationally by AreaSearch.
Recent population expansion has been predominantly underpinned by overseas migration, which accounted for around 82.0% of total demographic additions. Projections for the suburb of Dundas Valley utilize ABS/Geoscience Australia SA2 figures published in 2024 using 2022 as the base year, supplemented where necessary by NSW State Government SA2 projections from 2022 based on 2021. For the period spanning 2032 to 2041, cohort-specific age growth rates from these datasets are applied across all locations. Demographic forecasts place the suburb in the top quartile nationally for long-term expansion, with an anticipated increase of 1,509 persons by 2041 according to aggregated SA2 modeling, representing an overall gain of 25.4% across the 16 years.
Frequently Asked Questions - Population
200 new dwellings have been approved in Dundas Valley over the past five years, an average of 40 a year. That is 5.0 approvals per 1,000 residents. Of the 29 dwellings approved in the latest reporting year, 24% were detached houses and the rest townhouses or apartments. Approvals are currently running at an annualised 23, well below that longer-run average. Figures come from ABS building approvals aggregated to this Suburb (SAL) boundary and are updated monthly as the ABS releases them.
Detail
Building approval figures compiled by AreaSearch from ABS statistical collections show an annual average of around 40 new residential approvals in Dundas Valley, totaling an estimated 200 approved dwellings across the 5 financial years from FY-21 to FY-25, including 23 approvals during FY-25 to date. Against a backdrop of recent population declines, incoming residential construction has satisfied local demand while providing ample purchasing options. The expected construction cost for new dwellings averages $1,087,000, highlighting builder focus on the higher-end, premium residential segment. Non-residential development has remained muted, evidenced by $2.1 million in approved commercial activity during the current financial year.
Per-capita residential construction in Dundas Valley is 61.0% below the regional average for Greater Sydney, reflecting comparatively constrained building volumes that help sustain established property values and steady buyer demand. Attached medium and high-density developments account for 76.0% of recent approvals compared to 24.0% for standalone houses, delivering accessible options suited to first-home buyers, downsizers, and property investors. This development pattern marks a significant transition from the existing built environment, where detached houses make up 65.0% of housing, responding to constrained land supply alongside evolving lifestyle and affordability considerations in an established market featuring approximately 352 people per dwelling approval. According to the latest quarterly calculations from AreaSearch, Dundas Valley is projected to welcome an additional 1,485 residents by 2041. Ongoing residential construction volumes align well with this expected influx, supporting balanced market conditions and preventing undue upward price pressure.

The working-day population is estimated at 4,465, about 76% of the resident population, so more people leave the area for work than travel in. Unemployment and labour force come from ABS Small Area Labour Markets, updated quarterly; the industry and occupation profile is from the 2021 Census.
Detail
Dundas Valley is characterized by an educated resident workforce featuring a sizable professional services contingent, an unemployment rate of 4.9%, and year-on-year employment growth estimated at 1.5% via AreaSearch statistical area modeling. Employed residents totaled 3,158 as of March 2026. The local jobless rate sits 0.8% higher than the 4.1% recorded for Greater Sydney, while labor force participation matches the metropolitan benchmark of 68.9%. Census records indicate that 47.8% of local workers performed their duties from home, an outcome influenced in part by prevailing Covid-19 restrictions. The resident labor base is primarily concentrated within health care & social assistance, professional & technical services, and education & training.
Wholesale trade forms a key area of local specialization, capturing a workforce share 1.6 times greater than the broader region. Conversely, finance & insurance represents 5.4% of local employment relative to 7.3% across the wider region. Comparisons between the resident workforce and the local Census working population underline the area's predominantly residential character and modest internal employment footprint. SALM and ABS data aggregated across broader statistical districts by AreaSearch indicates that during the 12 months to March 2026, local employment expanded by 1.5% against a 1.6% rise in the labor pool, maintaining unemployment stability. Over the same period, Greater Sydney experienced employment and labor force growth of 1.9% and 1.9% respectively, accompanied by a slight drop in unemployment. Broader workforce projections released by Jobs and Skills Australia in Mar-26 outline national employment growth of 6.6% over five years and 13.7% over ten years, with performance varying across sectors. When weighted against the local industry structure for illustrative purposes, Dundas Valley's employment base is projected to expand by 6.8% over five years and 14.0% over ten years (excluding localized population adjustments).

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 — 44 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (5,875 at the 2021 Census → 5,838 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 Aug 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.
