Sales Detail
Castle Cove has an estimated 2,664 residents. That puts 1,139 residents on each square kilometre. Population is estimated from ABS Estimated Resident Population releases and GNAF address data, re-based from the 2021 Census and updated annually.
Detail
According to AreaSearch's evaluation of broader ABS population revisions alongside address records verified post-Census, the suburb of Castle Cove has a population of approximately 2,664 as of Aug 2026. This represents a gain of 21 people (0.8%) compared to the 2021 Census tally of 2,643 people. Such adjustment draws upon the resident baseline of 2,659 calculated by AreaSearch using the ABS June 2025 ERP update, combined with 16 validated new addresses post-dating the Census. This population yields a density of 1,138 persons per square kilometer, aligning closely with standard benchmarks across AreaSearch study locations.
Inward movement from overseas served as the primary catalyst, effectively underpinning all demographic increases in recent times. Projections for each SA2 district utilise 2024 ABS/Geoscience Australia datasets pegged to a 2022 base year, supplemented by 2022 NSW State Government SA2 modeling anchored to 2021 where needed. Age-specific growth metrics from these series are extended across all localities spanning 2032 to 2041. Over this timeframe, demographic forecasts anticipate an overall contraction for the suburb of Castle Cove, shrinking by 25 persons by 2041 under this framework. Conversely, certain cohorts will expand, notably individuals aged 85 and over, which is projected to grow by 113 people. See the age section for more details.
Frequently Asked Questions - Population
57 new dwellings have been approved in Castle Cove over the past five years, an average of 11 a year. That is 4.8 approvals per 1,000 residents. Approvals are currently running at an annualised 14, 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
Building approval metrics from the ABS, mapped across statistical boundaries by AreaSearch, show the suburb of Castle Cove averaging approximately 11 new residential approvals annually, totaling 57 homes across the past 5 financial years (between FY-21 and FY-25) with 14 approved during FY-25 to date. Against a backdrop of recent demographic contraction, construction volume has remained balanced, aiding prospective purchasers, while approvals carry a mean build cost of $1,861,000, demonstrating that builders are concentrating on the high-end residential tier. Furthermore, $508,000 in non-residential approvals was logged during the current financial year, underscoring subdued commercial building activity.
Per capita residential approvals in the suburb of Castle Cove track at roughly three-quarters of the Greater Sydney benchmark, positioning the locality in the 54th percentile across the country. Recent building activity is divided between 46.0% detached houses and 54.0% multi-unit or attached dwellings. This shift toward medium-density housing introduces attainable options suited to downsizers, first-home purchasers, and investors. It diverges markedly from the prevailing housing stock (currently 91.0% houses), highlighting limited greenfield capacity alongside shifts in lifestyle choices and price considerations. Generating one approval per 265 people, the area maintains a low-density profile. With demographic forecasts pointing toward flat or declining numbers, the suburb of Castle Cove is likely to see reduced housing demand pressures, providing advantageous conditions for property buyers.

1,281 residents of Castle Cove are employed, from a labour force of 1,315. Unemployment sits at 2.6%, with participation at 59.2%. Weighted for its industry mix, the area's sectors are forecast to grow about 7.5% nationally over five years. That reflects industry composition only and makes no allowance for local population growth. The working-day population is estimated at 2,357, about 88% 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 force is characterized by high qualifications, particularly in the tech sector, accompanied by an unemployment rate of only 2.6% and a 1.7% increase in jobs over the preceding year according to AreaSearch statistical area modeling. By March 2026, employed residents numbered 1,281, while the jobless rate sits 1.5% beneath the Greater Sydney figure of 4.1%, though the participation rate of 59.2% trails the broader metropolitan level of 68.9%. Census records indicate that 61.0% of workers operated from home, an outcome influenced by Covid-19 restrictions. Key fields of resident employment comprise professional & technical, finance & insurance, and health care & social assistance.
Local participation in professional & technical fields is especially pronounced, tracking at 1.9 times the broader metropolitan baseline. In contrast, public administration & safety accounts for a modest 2.4% of workers, versus 5.7% across the region. As reflected by the variance between resident workers and local jobs at the Census, this predominantly residential district provides few commercial employment opportunities within its borders. Through synthesis of ABS and SALM figures across wider statistical geographies, AreaSearch determined that during the 12 months to March 2026, resident employment rose by 1.7% against a 1.2% expansion in the labour pool, reducing local unemployment by 0.5 percentage points. Throughout Greater Sydney over the identical timeframe, employment advanced by 1.9%, the labour supply rose by 1.9%, and joblessness experienced a slight reduction. Long-term outlooks from Jobs and Skills Australia dated Mar-26 provide perspective on upcoming workforce demand in the locality. Projections over five and ten years, applied to the resident profile, highlight diverging sector trajectories against national growth benchmarks of 6.6% over five years and 13.7% over ten years. Weighted against the local industry baseline, employment is modeled to rise by 7.5% over five years and 14.8% over ten years (representing an illustrative weighting that excludes micro-level population trends).

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 — 16 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (2,643 at the 2021 Census → 2,664 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.
