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 research conducted by AreaSearch, the population of Bilpin - Colo - St Albans stands at approximately 2,783 as of Aug 2026. Relative to the 2021 Census tally of 2,846 people, this represents a reduction of 63 people (2.2%). Such figures are derived from the ABS estimated resident population of 2,781 recorded as of June 2025 alongside an extra 8 validated new addresses registered post-Census. With a resulting density of 1.3 persons per square kilometer, local inhabitants enjoy considerable space. Recent demographic expansion was predominantly underpinned by overseas migration, which made up around 69.5% of total net additions across recent periods.
Projections developed by ABS/Geoscience Australia from 2024, utilising 2022 as their starting point, are adopted by AreaSearch across SA2 regions, supplemented by NSW State Government SA2 forecasts released in 2022 (using a 2021 baseline) where coverage gaps exist. Cohort-specific growth trajectories from these datasets are extended across all localities from 2032 to 2041. Under this modeling framework, the district is slated for demographic contraction, with an expected net loss of 270 persons by 2041. Conversely, select older segments will expand, most notably individuals aged 85 and over, who are forecast to increase by 105 people. See the age section for more details.

22 new dwellings have been approved in Bilpin - Colo - St Albans over the past five years, an average of 4 a year. That is 1.6 approvals per 1,000 residents. 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 Bilpin - Colo - St Albans have run at approximately 4 per annum, totaling 22 homes authorized during the previous 5 financial years (from FY-22 to FY-26). Given recent population contraction, this level of construction has balanced demand effectively, affording prospective purchasers solid selection while newly built residences average an estimated construction cost of $552,000. Additionally, $6.2 million in commercial development approvals was logged during the current financial year, underscoring a modest non-residential pipeline. When measured against Greater Sydney, per-capita dwelling authorizations in Bilpin - Colo - St Albans sit at roughly three-quarters the metropolitan level, placing the locality in the 26th percentile across the country; this restricted volume helps sustain interest across established stock.
Approvals also trail nationwide benchmarks, highlighting the established character of the area and pointing toward possible regulatory constraints. Furthermore, all recent residential consents have been for standalone houses, preserving a low-density rural setting tailored to buyers desiring land. With an estimated ratio of 664 people per approved residence, local building activity remains exceptionally subdued. As local headcounts are projected to contract or remain steady, easing residential pressure across Bilpin - Colo - St Albans may generate favorable conditions for prospective purchasers.

Detail
A capable local labor pool characterizes Bilpin - Colo - St Albans, highlighted by strong presence in construction and an overall jobless rate of 7.0%. There are 1,451 working residents as of March 2026, while local unemployment sits 2.9% higher than the 4.1% recorded for Greater Sydney. Overall participation reaches 64.5%, lagging behind the broader Sydney benchmark of 68.9%. Census returns also indicated that 32.6% of workers carried out their duties from home, though prevailing Covid-19 pandemic restrictions during that period should be noted. Local workers are primarily engaged in construction, health care & social assistance, alongside education & training.
The community exhibits a distinct specialization in construction, where employment density is 1.8 times the broader metropolitan baseline. In contrast, professional & technical roles are comparatively sparse, engaging only 5.6% of local workers versus 11.5% throughout Greater Sydney. Comparing resident workers against jobs located within the boundary suggests that internal employment opportunities remain constrained. AreaSearch evaluations of ABS and SALM figures indicate that in the twelve months to March 2026, the local workforce shrank by 0.2% as total employment dropped by 1.1%, pushing the unemployment rate up by 0.8 percentage points. This contrasts with Greater Sydney, where employment expanded by 1.9%, the labor force grew by 1.9%, and joblessness fell slightly. Forward guidance from Jobs and Skills Australia as of Mar-26 provides additional context on prospective labor requirements in Bilpin - Colo - St Albans. Nationally, job numbers are projected to increase by 6.6% over five years and 13.7% over ten years, with distinct variation by sector. Applying these broader industry trends to the area's current industrial base points to local job gains of 5.9% across five years and 12.5% across ten years (noting this is a weighted extrapolation provided for demonstration and omits localized demographic forecasts).

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 — 8 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (2,846 at the 2021 Census → 2,783 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.
