This analysis uses Suburbs and Localities (SAL) boundaries, which can materially differ from Statistical Areas (SA2) even when sharing the same name.
SAL boundaries are defined by Australia Post and the Australian Bureau of Statistics to represent commonly-known suburb names used in postal addresses.
Statistical Areas (SA2) are designed for census data collection and may combine multiple suburbs or use different geographic boundaries. For comprehensive analysis, consider reviewing both boundary types if available.

Sales Detail
Leabrook has an estimated 1,550 residents, down from 1,605 at the 2021 Census — a change of 55 people, or 3.4%. The population has thinned by an average 0.9% a year over five years, slower than 98% of areas nationally. That puts 2,460 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
In the suburb of Leabrook, the population stands at approximately 1,550 as of Aug 2026, according to AreaSearch evaluations combining regional ABS updates with post-Census address validations. This represents a contraction of 55 people (3.4%) from the 1,605 people recorded at the 2021 Census. AreaSearch arrived at this through an estimated resident total of 1,549, derived from the ABS ERP figures released in June 2025 alongside subsequent address confirmations. With 2,460 persons per square kilometer, the locality's population density places it within the top quartile of areas assessed nationally by AreaSearch.
Inbound international migration served as the primary and almost exclusive catalyst for recent demographic additions in the suburb of Leabrook. Demographic projections utilise ABS and Geoscience Australia modelling published in 2024 with a 2022 baseline for local SA2 zones. Where coverage is lacking or forecasts extend past 2032, State Government Regional/LGA figures from 2023 based on 2021 numbers are incorporated through a weighted distribution method from LGA down to SA2 divisions. Looking ahead, the suburb of Leabrook is anticipated to achieve population growth exceeding the median across statistical areas tracked by AreaSearch, adding 270 persons up to 2041 under aggregated SA2 projections, which constitutes an overall expansion of 17.4% across the 16 years.
Frequently Asked Questions - Population
49 new dwellings have been approved in Leabrook over the past five years, an average of 9 a year. That is 6.1 approvals per 1,000 residents. Few approvals have been recorded in the most recent months, well below the longer-run average; the latest ABS periods are still being reported. Figures come from ABS building approvals aggregated to this Suburb (SAL) boundary and are updated monthly as the ABS releases them.
Detail
Examining ABS residential approvals apportioned from statistical datasets, AreaSearch estimates that Leabrook has generated roughly 9 residential building approvals annually, accumulating 49 homes over the previous 5 financial years. Throughout FY-25 to date, no approvals have been recorded. Given the local contraction in resident numbers, this level of construction has likely kept pace with purchasing needs, preserving sound market availability. Per capita residential development in Leabrook closely mirrors Greater Adelaide, maintaining an overall equilibrium in line with the broader metropolitan environment despite an easing in building volumes lately. Recent project approvals comprise 10.0% detached houses alongside 90.0% townhouses or apartments.
This pivot toward higher-density dwelling options creates viable possibilities for entry-level purchasers, investors, and downsizers. It also signals a pronounced transition away from the established stock profile of 40.0% houses, reflecting a scarcity of greenfield allotments, shifting demographic preferences, and demand for varied price points. Demographic projections suggest Leabrook will expand by 269 residents heading toward 2041, measured against the most recent AreaSearch quarterly release. While current residential construction broadly tracks this forecast expansion, prospective purchasers may face heightened competition as the local community grows.

702 residents of Leabrook are employed, from a labour force of 703. Unemployment sits at 0.1%, with participation at 50.3%. Weighted for its industry mix, the area's sectors are forecast to grow about 7.7% nationally over five years. That reflects industry composition only and makes no allowance for local population growth. The working-day population is estimated at 1,357, 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
Leabrook possesses a well-credentialed resident labour pool with considerable representation across professional disciplines, a minimal jobless rate of 0.1%, and an estimated 2.9% rise in employment over the preceding year according to AreaSearch aggregates. Figures for March 2026 show 702 employed locals, with local unemployment sitting 3.7% beneath the Greater Adelaide level of 3.8%. Meanwhile, workforce participation trails significantly at 50.3% against the metropolitan mark of 66.4%. At the Census, 18.5% of working residents carried out their duties from home, though prevailing Covid-19 restrictions should be factored into this figure.
Resident workers are primarily engaged in health care & social assistance, professional & technical roles, and education & training. Professional and technical activities show exceptional concentration locally, recording a representation 2.1 times the wider regional benchmark. Conversely, building trades account for only 5.4% of the working resident base, underperforming the 8.7% recorded for Greater Adelaide. Comparison between local resident totals and Census workplace figures indicates that this largely residential setting provides constrained employment within its borders. Based on AreaSearch analysis of SALM and ABS data, aggregated from broader statistical areas, over the 12 months to March 2026, employment increased by 2.9% while labour force increased by 2.8%, resulting in unemployment fall by 0.2 percentage points. This compares to Greater Adelaide, where employment grew by 4.2%, labour force expanded by 4.0%, and unemployment fell 0.2 percentage points. Jobs and Skills Australia's national employment forecasts from Mar-26 can offer further insight into potential future demand within Leabrook. These projections, covering five and ten-year periods, have been mapped against the local employment profile to estimate growth patterns. While national employment is forecast to expand by 6.6% over five years and 13.7% over ten years, growth rates differ significantly between industry sectors. Applying these industry-specific projections to Leabrook's employment mix suggests local employment should increase by 7.7% over five years and 15.6% over ten years (please note this is a simple weighting extrapolation for illustrative purposes and does not take into account localised population 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. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (1,605 at the 2021 Census → 1,550 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.
