Detail
As of Aug 2026, the suburb of Two Rocks has an estimated population of approximately 5,767, determined through AreaSearch's evaluation of broader regional ABS population updates and newly verified addresses since the Census. Compared to the 2021 Census count of 3,822 residents, this marks an expansion of 1,945 people (50.9%). This estimate builds upon an ERP of 5,214 calculated by AreaSearch from the ABS June 2025 data release, combined with 1,097 post-Census validated new addresses. The resulting density stands at 111 persons per square kilometer, indicating generous space per resident alongside scope for future development.
Outperforming both the SA4 region and the national average (9.5%), the 50.9% population increase in the suburb of Two Rocks since the 2021 census positions it as a leading growth locality. Inflows from interstate migration served as the primary growth catalyst, generating roughly 71.0% of recent population additions, while natural growth and overseas arrivals also provided positive gains. Projections for each SA2 district applied by AreaSearch draw on 2024 ABS/Geoscience Australia releases anchored to 2022. Across SA2 localities lacking this coverage, as well as for all projections beyond 2032, growth rates across age segments from the 2023 ABS Greater Capital Region release (using 2022 base data) are incorporated. Demographic modeling places the suburb of Two Rocks among the country's top quartile of statistical areas for population expansion, with combined SA2 projections indicating an addition of 1,245 persons to 2041, representing a cumulative rise of 12.0% over the 16 years.
Frequently Asked Questions - Population
928 new dwellings have been approved in Two Rocks over the past five years, an average of 185 a year. That places the area in the 89th percentile for residential development activity nationally, about 32 approvals per 1,000 residents a year. Of the 259 dwellings approved in the latest reporting year, 98% were detached houses and the rest townhouses or apartments. Approvals are currently running at an annualised 476, running ahead of 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
An analysis of ABS building approvals across statistical areas shows annual residential approvals averaging approximately 185 in Two Rocks, accumulating to an estimated 928 dwellings over the preceding 5 financial years. Within FY-25 to date, 476 dwelling approvals have been logged. The arrival rate of 1.1 new residents per approved dwelling across the last 5 financial years (from FY-21 to FY-25) points to well-aligned supply and demand that underpins stable market conditions, with new homes registering an average construction value of $426,000. In addition, commercial approvals have reached $4.5 million during the ongoing financial year, underlining the dominant residential orientation of local development.
Per capita residential building activity in Two Rocks outpaces Greater Perth by 371.0%, affording broader selection for purchasers. This rate sits well above nationwide benchmarks, highlighting substantial builder and developer interest. Single-family detached houses represent 98.0% of new projects while attached homes make up 2.0%, reinforcing low-density neighborhood planning geared toward buyers seeking open space. An average ratio of approximately 12 people per residential approval underscores the ongoing urbanization of the area. According to the latest quarterly figures from AreaSearch, Two Rocks is projected to gain 692 residents by 2041. Ongoing construction activity indicates that new housing deliveries should readily satisfy future resident demand, maintaining favourable market conditions and potentially facilitating growth exceeding current demographic projections.

2,277 residents of Two Rocks are employed, from a labour force of 2,490. Unemployment sits at 8.6%, with participation at 60.5%. 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, 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 4,847, about 84% 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
Two Rocks maintains a diverse employment landscape across blue and white collar roles, highlighted by notable strength in the building and construction trades, alongside an unemployment rate of 8.6% and a 1.6% yearly increase in jobs, based on AreaSearch statistical area aggregations. By March 2026, 2,277 residents were employed, though the local jobless rate exceeds Greater Perth's 4.2% by 4.4%, suggesting potential for labor market strengthening, while the 60.5% participation rate trails Greater Perth's 69.9%. Census records indicate that 8.3% of workers worked from home, a metric that may have been influenced by Covid-19 restrictions.
Local workers are primarily concentrated in construction, mining, and health care & social assistance. Mining shows particular local specialization, accounting for a workforce proportion 2.1 times higher than the broader region. Conversely, professional & technical occupations are underrepresented, engaging 4.2% of Two Rocks workers compared to 8.2% across Greater Perth. A comparison between Census working figures and the resident population reflects a relatively small base of local employment opportunities. AreaSearch evaluation of ABS and SALM figures indicates that during the 12 months leading to March 2026, local employment grew by 1.6% against a 3.9% expansion in the labor force, resulting in a 2.1 percentage point rise in unemployment. Over the identical timeframe, Greater Perth saw employment rise by 2.0% and the workforce grow by 2.5%, yielding a 0.4 percentage point uptick. National forecasts from Jobs and Skills Australia as of Mar-26 provide broader perspective on future hiring trends. While overall national employment is projected to expand by 6.6% across five years and 13.7% across ten years, sector trajectories vary considerably. Modeling these sector forecasts against the local industry composition points to projected employment increases in Two Rocks of 5.8% over five years and 12.5% over ten years (calculated via simple weighted distribution for illustrative purposes without factoring in 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 — 1,097 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (3,822 at the 2021 Census → 5,767 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 (SAL51475). QuickStats reports 2021 only — the figures on this page are more current wherever the ledger shows a later date.
