Statistical Area (SA2) Boundary Analysis

This analysis uses ABS Statistical Areas Level 2 (SA2) boundaries, which can materially differ from Suburbs and Localities (SAL) even when sharing similar names.

SA2 boundaries are defined by the Australian Bureau of Statistics and are designed to represent communities for statistical reporting (e.g., census and ERP).

Suburbs and Localities (SAL) represent commonly-used suburb/locality names (postal-style areas) and may use different geographic boundaries. For comprehensive analysis, consider reviewing both boundary types if available.

Detail

According to the analysis by AreaSearch, the population of Williamstown stands at approximately 17,197 as of May 2026. This represents a growth of 1,285 individuals (8.1%) relative to the 2021 Census, which counted 15,912 residents. This shift is calculated using the ABS estimated resident population of 17,102 from June 2025 alongside 590 validated new addresses registered after the Census. The resulting population density is 2,339 persons per square kilometer, placing the locality in the top quartile of all areas evaluated nationwide by AreaSearch. The 8.1% rate of expansion since the 2021 census outpaced the broader SA3 region (6.8%), establishing the suburb as a local growth leader.

Overseas migration served as the main contributor, accounting for roughly 90.6% of the population increase in recent times, though interstate migration, natural growth, and all other components remained positive. AreaSearch utilizes the 2024 population projections from the ABS and Geoscience Australia, which use 2022 as their baseline year. For any SA2 locations lacking this dataset, figures are derived from the 2023 Victorian State Government Regional/LGA projections, adjusted via a weighted aggregation methodology that maps population changes from the LGA scale down to SA2 zones. Age bracket growth rates calculated from these aggregations are also applied across all regions for the period spanning 2032 to 2041. Future demographic trends indicate an expansion rate exceeding the national median, with the locality projected to add 2,867 residents by 2041 based on the most recent annual ERP figures, representing a total increase of 16.1% over the 16 years.

Residential SupplyHousing Development & Building Approvals in Williamstown

Table Chart PROFILE FAQ

513 new dwellings have been approved in Williamstown over the past five years, an average of 102 a year. That is 6.3 approvals per 1,000 residents. Of the 76 dwellings approved in the latest reporting year, 17% were detached houses and the rest townhouses or apartments. Approvals are currently running at an annualised 21, well below that longer-run average. Figures come from ABS building approvals aggregated to this SA2 boundary and are updated monthly as the ABS releases them.

Detail

On average, Williamstown sees approximately 102 residential building approvals annually, translating to a total of 513 homes over the last 5 financial years. In the current FY-26 period, 20 approvals have been documented so far. With only 0.9 residents moving to the locality for every new home constructed over the past 5 financial years (from FY-21 to FY-25), local building activity is meeting or exceeding demand, providing home buyers with more choices and supporting population gains that could surpass projected figures, with new dwellings carrying an average build value of $416,000.

Additionally, commercial development approvals totaling $21.7 million have been logged during this financial year, showing consistent business investment. In comparison to Greater Melbourne, building activity per resident in Williamstown is at approximately 67%, placing it in the 30th percentile of locations nationwide, which restricts choice for buyers and helps sustain demand for established housing. The composition of new residential approvals stands at 17.0% detached houses and 83.0% medium and high-density options. This movement toward denser options provides more accessible entry prices and appeals to downsizers, real estate investors, and first-time buyers. It represents a clear change from the existing housing stock (which comprises 54.0% houses), indicating a reduction in available development sites alongside shifting lifestyles and a demand for more varied, affordable housing. With approximately 594 residents for every single residential approval, Williamstown presents as a highly established real estate market. Demographic forecasts suggest that Williamstown is on track to add 2,772 residents by 2041, according to the latest quarterly estimates from AreaSearch. The current rate of construction seems well aligned with these future requirements, encouraging stable market conditions without causing drastic price spikes.

Development approvals is a new addition to AreaSearch. We’re actively expanding council coverage and refining the dataset — details and statuses for some councils may be partial. Check back regularly for the latest pipeline.
Application search is not available in Victoria. AreaSearch holds 80 applications for Williamstown, but they are a record of past activity rather than a current register. Victoria has no state-wide planning portal and its council coverage is uneven, so we have switched the search off here rather than return partial answers. We are currently investigating a solution. No credits are charged for Victorian applications, and building approvals from the ABS and the major projects we track are unaffected.

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 — 590 validated new addresses here. The headline figure is therefore a current estimate for May 2026, not a 2021 count (15,912 at the 2021 Census → 17,197 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.

Cross-check us. The Census baseline for this boundary is at ABS 2021 Census QuickStats (213021346). QuickStats reports 2021 only — the figures on this page are more current wherever the ledger shows a later date.

Common questions about this page

Why can the Williamstown SA2 boundary differ from the suburb boundary?
This page uses ABS Statistical Area Level 2 (SA2) boundaries for statistical reporting (e.g., census and ERP). SA2 areas can differ materially from Suburbs and Localities (SAL) boundaries, even when they share similar names, because they are defined for different purposes and often use different geographic boundaries.
Where does the data on this Williamstown page come from?
AreaSearch compiles this page from official and industry sources — including ABS, Geoscience Australia, Valuer General, Provider directories, DEWR, JSA, State Transport Departments and ACARA — then aggregates them to the boundary shown and calculates the rankings, growth rates and benchmarks itself. Property sales come from the state valuation authority, rents from state rental bond lodgements, development applications from council and state planning portals, school data from ACARA, and public transport from state transport departments.
Is the Williamstown data on this page just from the 2021 Census?
No. Most of this page is maintained well beyond the Census. Sourced entirely from current releases: development & approvals (Jun 2026), property sales & rents (Aug 2026), infrastructure projects (Aug 2026) and services & amenities (Jul 2026). Built on a Census baseline but carrying newer measures on top: population (to May 2026), age profile (to May 2026), employment (to Mar 2026), income (to FY 2023), education (to Aug 2026), transport (to Jul 2026) and health (to 2024). Population and age cohorts in particular are re-based to the latest ABS Estimated Resident Population rather than left at 2021 counts. Only housing, households and cultural diversity remain wholly Census-based, because no more current small-area dataset exists for those measures.
