Sales Detail
Crystal Brook (SA) has an estimated 1,599 residents, up from 1,537 at the 2021 Census — a change of 62 people, or 4.0%. Fewer than ten people live on each square kilometre, across a boundary that takes in surrounding rural land. Population is estimated from ABS Estimated Resident Population releases and GNAF address data, re-based from the 2021 Census and updated annually.
Detail
Analysis of ABS demographic updates for the wider region and address information confirmed by AreaSearch post-Census indicates that the suburb of Crystal Brook (SA) has a population of approximately 1,599 as of May 2026. This represents an addition of 62 people (4.0%) relative to the 2021 Census, which recorded 1,537 people. This shift is calculated from a resident population of 1,596, projected by AreaSearch using the June 2025 ABS ERP release alongside 33 validated new addresses registered after the Census. The current population translates to a density of 8.3 persons per square kilometer, ensuring resident spaces remain highly open.
The 4.0% expansion rate in the suburb of Crystal Brook (SA) since the 2021 census outpaced the broader SA3 region (2.4%), positioning it as a local growth frontrunner. Interstate relocation served as the primary engine for this population increase, functioning as almost the exclusive source of demographic growth in recent times. Projections developed by the ABS and Geoscience Australia for individual SA2 zones, published in 2024 with a 2022 baseline, are utilised by AreaSearch. For SA2 territories excluded from these datasets and for periods extending past 2032, regional and LGA age-cohort projections from the SA State Government issued in 2023 based on 2021 information are applied, employing a weighted consolidation of population increases from the LGA scale down to the SA2 level. Factoring in these demographic transitions, growth is projected to align with the bottom quartile of national regional locations, with the suburb of Crystal Brook (SA) expected to add 34 residents by 2041 under consolidated SA2-level forecasts, representing a total increase of 1.9% over the 16 years.
Frequently Asked Questions - Population
24 new dwellings have been approved in Crystal Brook (SA) over the past five years, an average of 4 a year. That is 3.1 approvals per 1,000 residents. Approvals are currently running at an annualised 12, 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
ABS building approval statistics mapped to local boundaries indicate that Crystal Brook averages approximately 4 new residential approvals annually, yielding a total of 24 dwellings over the preceding 5 financial years. During FY-26 to date, 11 approvals have been documented. The ratio of 1.2 people entering the locality for every completed home between FY-21 and FY-25 suggests a healthy equilibrium between demand and supply, supporting market stability, with new dwellings recording an average construction value of $265,000. Commercial approvals have reached $1.6 million during the current financial year, indicating that the development landscape remains overwhelmingly residential.
Crystal Brook exhibits 56.0% higher development volume per resident than the Rest of SA, offering purchasers a wider range of options. However, this volume sits below the national average, indicating a established local property market and potential regulatory limits on planning. Recent construction activity has consisted exclusively of detached houses, preserving the established low-density profile of the locality and emphasizing family-oriented properties suited for buyers seeking extra space. With approximately 265 residents for each building approval, the area retains a low-density profile. Projections indicate that Crystal Brook will add 31 residents by 2041, measured from the most recent quarterly calculation by AreaSearch. With current construction velocities, supply is positioned to easily satisfy incoming demand, maintaining favorable conditions for prospective buyers and potentially enabling expansion that outpaces existing demographic forecasts.

663 residents of Crystal Brook (SA) are employed, from a labour force of 699. Unemployment sits at 5.3%, with participation at 52.3%. Weighted for its industry mix, the area's sectors are forecast to grow about 6.4% nationally over five years. That reflects industry composition only and makes no allowance for local population growth. The working-day population is estimated at 1,314, about 82% 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
Crystal Brook features a diverse labor pool that includes both skilled manual workers and office employees, with strong representation in sectors providing critical community services. According to AreaSearch data from statistical areas, the local unemployment stands at 5.3% and the projected job growth for the previous year reaches 3.6%. As of March 2026, there are 663 employed residents, and the local joblessness figure sits 0.2% lower than the Regional SA benchmark of 5.5%. However, the proportion of the population actively participating in the labor market is notably lower at 52.3%, falling behind the Regional SA rate of 58.4%.
Census data indicates that only 8.7% of residents engage in remote work, though this figure may reflect lingering effects from pandemic-related restrictions. Resident employment is concentrated within healthcare & social assistance, education & training, along with agriculture, forestry & fishing. The healthcare & social assistance sector exhibits strong concentration, employing residents at 1.6 times the regional average rate. Conversely, agriculture, forestry & fishing is less prominent locally, accounting for 9.7% of jobs compared to the regional benchmark of 14.5%. A comparison of the Census working population against the resident population suggests that the immediate locality provides restricted job opportunities. Based on SALM and ABS statistics aggregated across broader zones, the 12 months leading to March 2026 saw employment expand by 3.6% and the total labor force rise by 3.9%, which elevated the unemployment rate by 0.4 percentage points. Over the same timeframe, Regional SA experienced a 1.2% rise in employment, a 2.6% increase in the labor force, and a 1.4 percentage point rise in unemployment. National occupational projections from May-25 compiled by Jobs and Skills Australia provide further context regarding future labor demand. These five and ten-year projections have been applied to the local workforce structure to model potential growth. Although overall Australian employment is projected to rise by 6.6% over five years and 13.7% over ten years, trends vary widely by industry. Weighting these sectoral forecasts against the local workforce mix suggests employment in the area should rise by 6.4% over five years and 13.7% over ten years.

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 — 33 validated new addresses here. The headline figure is therefore a current estimate for May 2026, not a 2021 count (1,537 at the 2021 Census → 1,599 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.
