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.

Sales Detail
Two Rocks has an estimated 5,767 residents, up from 3,822 at the 2021 Census — a change of 1,945 people, or 50.9%. Growth has averaged 6.6% a year over five years, faster than 97% of areas nationally. 1,097 new addresses have been validated here since Census night.

Population is estimated from ABS Estimated Resident Population releases and GNAF address data, re-based from the 2021 Census and updated annually.
Detail
Demographic estimates from AreaSearch place the population of Two Rocks at approximately 5,767 as of Aug 2026. This represents a gain of 1,945 people (50.9%) compared to the 2021 Census tally of 3,822 people. This calculation relies on the ABS estimated resident population of 5,214 as of June 2025 alongside 1,097 validated new addresses identified following the Census date. With a resultant density of 104 persons per square kilometer, the locality offers substantial physical room for residents as well as potential for ongoing expansion. Outperforming both the broader SA4 region and the national average (9.5%), the locality's 50.9% post-2021 census expansion establishes it as a primary regional growth node.
Net interstate migration served as the foremost growth driver, underpinning roughly 75.4% of recent gains, while overseas arrivals and natural increase also provided positive contributions. Projections generated by Geoscience Australia and the ABS from 2024, utilising 2022 as a base, form the foundation of AreaSearch's SA2 modelling. Where local coverage is absent, and for broader forecasting past 2032, cohort-specific growth rates from the 2023 ABS Greater Capital Region projections (grounded in 2022 data) are applied. Looking ahead, long-term demographic trajectories place the district within the highest quartile nationwide, with an anticipated expansion of 1,248 persons to 2041 relative to latest annual ERP statistics, representing a cumulative 16-year increase of 12.1%.
Frequently Asked Questions - Population
1,294 new dwellings have been approved in Two Rocks over the past five years, an average of 258 a year. That places the area in the 89th percentile for residential development activity nationally, about 45 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. Figures come from ABS building approvals aggregated to this SA2 boundary and are updated monthly as the ABS releases them.
Detail
Residential building approvals in Two Rocks have averaged roughly 258 per annum, accumulating to 1,294 homes across the preceding 5 financial years. Between FY-22 and FY-26, the area saw an influx of approximately 1.1 people per year for every home constructed over the last 5 financial years, demonstrating an equilibrium between housing supply and resident demand that reinforces market stability. Approved residential projects reflect an average expected construction cost of $383,000 per dwelling. Furthermore, commercial approvals amounting to $4.5 million during the current financial year emphasize the overwhelmingly residential focus of local building activity.
Per capita building activity in Two Rocks exceeds Greater Perth by 371.0%, affording prospective purchasers an extensive array of options. This figure stands well clear of national benchmarks, highlighting elevated developer interest. The construction pipeline is overwhelmingly oriented toward detached residences at 98.0%, alongside 2.0% medium and high-density housing, preserving the low-density coastal suburban environment and appealing to buyers seeking larger allotments. With roughly 12 people per dwelling approval, the locality exhibits key traits of an active growth corridor. According to the latest quarterly calculations from AreaSearch, Two Rocks is projected to gain 695 residents by 2041. Ongoing construction trends suggest that future dwelling completions will adequately satisfy buyer demand, maintaining favorable purchasing conditions and potentially enabling demographic expansion beyond existing baseline forecasts.

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 4,856, 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
The local labour pool displays an even distribution across blue-collar and white-collar roles, with building and construction showing substantial presence. As of March 2026, employed residents count 2,277, accompanied by an unemployment rate of 8.6% and a 1.6% rise in estimated local employment over the trailing year. Local unemployment exceeds the Greater Perth benchmark of 4.2% by 4.4 percentage points, highlighting scope for improvement, while the labour force participation rate of 60.5% trails the 69.9% recorded across Greater Perth. Census records show just 8.3% of workers operating from home, though this metric was captured during Covid-19 lockdown periods.
Resident employment centers predominantly on the construction, mining, and health care & social assistance sectors. The mining industry shows exceptional concentration, engaging a workforce proportion 2.1 times the regional average. By contrast, the professional & technical sector is underrepresented, capturing 4.2% of workers relative to 8.2% across the wider region. Comparisons between the resident workforce and the volume of locally based jobs point to a constrained internal employment market. AreaSearch assessment of ABS and SALM metrics indicates that annual local employment expanded by 1.6% against a 3.9% rise in the total labour force, which pushed the unemployment rate up by 2.1 percentage points. Over the identical timeframe, Greater Perth saw employment and workforce numbers increase by 2.0% and 2.5% respectively, resulting in a 0.4 percentage point rise in joblessness. National outlooks published by Jobs and Skills Australia from Mar-26 provide further context on potential hiring trends for Two Rocks. When five- and ten-year national industry forecasts—projecting overall growth of 6.6% and 13.7% respectively—are mapped to the local industry base, employment for Two Rocks is modeled to grow by 5.8% over five years and 12.5% over ten years (noting this is an illustrative weighting model that does not incorporate specific demographic 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 — 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.
