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 the analysis conducted by AreaSearch, the population of Bilpin - Colo - St Albans is estimated at 2,783 as of May 2026. This represents a contraction of 63 individuals (2.2%) from the 2,846 residents recorded in the 2021 Census. This shift is calculated using the June 2025 ABS estimated resident population of 2,781 alongside 8 validated new addresses registered after the Census. The population density stands at 1.3 persons per square kilometer, indicating a spacious residential environment. Recent population gains were predominantly fueled by overseas migration, which accounted for roughly 69.5% of the total growth.
AreaSearch incorporates projections from the ABS and Geoscience Australia published in 2024, utilising 2022 as the starting point. For any SA2 regions lacking this coverage, projections from the NSW State Government released in 2022 with a 2021 baseline are applied instead. Age cohort growth rates derived from these sources are extended to span the years 2032 to 2041. Based on these anticipated demographic trends, the overall population is projected to shrink by 268 persons by 2041. Conversely, expansion is expected within particular age brackets, most notably the 85 and over cohort, which is forecast to grow by 108 individuals. Details regarding age breakdowns are available in the corresponding section.

In FY-26, there have been 3 approvals documented so far. Amidst recent population declines, the supply of housing has kept pace with demand to maintain a balanced market with options for purchasers, while new residential builds show an average construction cost of $408,000. Additionally, commercial approvals worth $6.2 million have been logged in the current financial year, highlighting the predominantly residential character of the locality.
Compared to Greater Sydney, the rate of new development per capita in Bilpin - Colo - St Albans is 14.0% lower, placing it in the 30th percentile of all regions analyzed across the nation, which translates to fewer options for buyers and bolsters demand for existing houses. This level also sits below the national benchmark, indicating a mature residential landscape and potential planning limitations. Furthermore, recent building activity consists entirely of separate houses, preserving the established low density layout and focusing on spacious family residences. A ratio of 666 people per single dwelling approval highlights the quiet nature of local construction activity. Faced with projections of a steady or contracting population, Bilpin - Colo - St Albans is likely to experience reduced pressure on housing, creating advantageous conditions for home buyers.

1,451 residents of Bilpin - Colo - St Albans are employed, from a labour force of 1,560. Unemployment sits at 7.0%, with participation at 64.4%. Weighted for its industry mix, the area's sectors are forecast to grow about 5.9% nationally over five years. That reflects industry composition only and makes no allowance for local population growth. The working-day population is estimated at 2,320, about 83% 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 workforce in Bilpin - Colo - St Albans is highly skilled, particularly in the building sector, and features an unemployment rate of 7.0%. There are 1,451 employed residents as of March 2026, with an unemployment rate that exceeds the Greater Sydney average of 4.1% by 2.9%. The participation rate of 64.4% is slightly below the Greater Sydney average of 69.1%. Census data indicates that 32.6% of working residents performed their jobs from home, although this figure may be influenced by pandemic-related restrictions. Local jobs are heavily concentrated in construction, health care & social assistance, and education & training.
The region displays a strong focus on the building sector, with its employment share reaching 1.8 times the regional benchmark. In contrast, the professional & technical sector accounts for just 5.6% of local jobs compared to the regional average of 11.5%. A comparison of the Census working population against the resident workforce suggests that local job opportunities are relatively scarce. An analysis of SALM and ABS statistics by AreaSearch shows that over the 12-month period, the local labor force contracted by 0.2% and total employment dropped by 1.1%, leading to an increase of 0.8 percentage points in the unemployment rate. This stands in contrast to Greater Sydney, where employment grew by 1.9% and the labor force expanded by 1.9%, accompanied by a minor decline. National projections released by Jobs and Skills Australia in May-25 offer perspective on future labor requirements in Bilpin - Colo - St Albans. These five and ten-year forecasts have been aligned with the local industry profile to estimate potential growth. Nationally, employment is expected to rise by 6.6% over five years and 13.7% over ten years, though individual sectors will experience different trajectories. Applying these national industry trends to the employment distribution of Bilpin - Colo - St Albans suggests local jobs could grow by 5.9% over five years and 12.5% over ten years, representing a basic weighted extrapolation that does not account for localized population changes.

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 May 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 May 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.
