Detail
As of Aug 2026, the suburb of Serpentine (WA) has an estimated population of around 3,316, calculated by AreaSearch through synthesis of broader ABS updates and post-Census validated address counts. This represents an expansion of 453 people (15.8%) compared to the 2,863 people recorded in the 2021 Census. Underlying this projection is an estimated resident population base of 3,255 derived from the ABS June 2025 ERP release, combined with 56 validated new addresses logged post-Census. Consequently, population density settles at a spacious 31 persons per square kilometer. With its 15.8% expansion rate since the 2021 census, the locality outpaced both Western Australia and the national average (9.5%), positioning it among regional leaders in growth.
Net interstate migration served as the primary growth catalyst, generating roughly 48.0% of all recent population additions, while overseas arrivals and natural increase also provided positive contributions. Projections for the suburb of Serpentine (WA) incorporate 2024 ABS/Geoscience Australia models pegged to a 2022 baseline across individual SA2 boundaries. For unmapped sections and horizons extending past 2032, calculations apply age-group trajectory rates from the ABS 2023 Greater Capital Region dataset (benchmarked to 2022). Looking ahead, population growth in the suburb of Serpentine (WA) is slated to track marginally below the median of AreaSearch study regions, expanding by 279 persons by 2041 under consolidated SA2 modelling to mark a cumulative 6.6% rise over the 16 years.
Frequently Asked Questions - Population
106 new dwellings have been approved in Serpentine (WA) over the past five years, an average of 21 a year. That places the area in the 70th percentile for residential development activity nationally, about 6 approvals per 1,000 residents a year. Of the 20 dwellings approved in the latest reporting year, 100% were detached houses and the rest townhouses or apartments. Approvals are currently running at an annualised 26, broadly in line with 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
Data on ABS residential approvals aggregated across statistical boundaries shows that Serpentine has averaged approximately 21 approved dwellings annually, yielding an estimated 106 homes across the last 5 financial years. The tally for FY-25 to date stands at 26 approvals. Over the 5 financial years between FY-21 and FY-25, the locality added an average of 4.2 new residents per annum for each residence constructed, creating an environment where demand heavily outstrips additions, traditionally driving competitive bidding and capital appreciation. New builds reflect an emphasis on premium standards, averaging $483,000 in construction value to sit above surrounding regional benchmarks.
In addition, commercial approvals registered at $3.8 million during this financial year, underscoring the predominantly residential focus of the locality. Per-capita building activity in Serpentine trails regional benchmarks significantly, recording 51.0% below the Greater Perth average. Such restricted pipeline delivery generally reinforces underlying value and buyer appetite for existing residential stock. Furthermore, recent development has consisted exclusively of detached residences, maintaining the spacious, low-density character of the area that attracts households seeking generous land holdings. Overall, development velocity sits at roughly 179 people per dwelling approval, demonstrating a growing market. Based on the most recent quarterly projections from AreaSearch, Serpentine is forecast to add 218 residents through to 2041. Ongoing construction activity suggests that future residential additions will adequately satisfy demand, establishing favourable conditions for property buyers and offering potential headroom to accommodate growth above baseline expectations.

1,572 residents of Serpentine (WA) are employed, from a labour force of 1,617. Unemployment sits at 2.8%, with participation at 57.9%. Weighted for its industry mix, the area's sectors are forecast to grow about 5.5% nationally over five years. That reflects industry composition only and makes no allowance for local population growth, so in an area growing as fast as this one it understates the likely rise in local jobs. The working-day population is estimated at 2,621, about 79% 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
Serpentine maintains a balanced employment base covering both manual and professional occupations, characterised by heavy workforce concentration in the construction sector, an unemployment rate standing at 2.8%, and annual job growth estimated at 1.9% via AreaSearch statistical area datasets. As of March 2026, employed residents total 1,572, while joblessness sits 1.4% below the 4.2% figure for Greater Perth. However, labour force participation remains lower at 57.9% compared to 69.9% across Greater Perth. Census findings indicated that 12.2% of workers operated from home, a metric influenced by prevailing Covid-19 restrictions. Primary employment sectors for local workers comprise construction, mining, and retail trade.
Agricultural, forestry & fishing activities exhibit immense local concentration, capturing a market share 8.3 times the regional standard. In contrast, health care & social assistance engages 8.3% of the local workforce, lagging the wider metropolitan level of 14.8%. Comparing the local resident workforce against the Census daytime working tally highlights a constrained internal job base. Based on AreaSearch analysis of SALM and ABS data, aggregated from broader statistical areas, during the year to March 2026, employment levels increased by 1.9% and labour force increased by 2.1%, causing the unemployment rate to rise by 0.2 percentage points. In contrast, Greater Perth experienced employment growth of 2.0% and labour force growth of 2.5%, with a 0.4 percentage point rise. Jobs and Skills Australia's national employment forecasts from Mar-26 can offer further insight into potential future demand within Serpentine. These projections, covering five and ten-year periods, have been mapped against the local employment profile to estimate growth patterns. While national employment is forecast to expand by 6.6% over five years and 13.7% over ten years, growth rates differ significantly between industry sectors. Applying these industry-specific projections to Serpentine's employment mix suggests local employment should increase by 5.5% over five years and 11.9% over ten years (please note this is a simple weighting extrapolation for illustrative purposes and does not take into account localised population projections).

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 — 56 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (2,863 at the 2021 Census → 3,316 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.
Cross-check us. The Census baseline for this boundary is at ABS 2021 Census QuickStats (SAL51339). QuickStats reports 2021 only — the figures on this page are more current wherever the ledger shows a later date.
