Statistical Area (SA2) Boundary Analysis

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 residing in One Tree Hill is estimated at approximately 2,522 as of Aug 2026. Relative to the 2021 Census tally of 2,473 people, this indicates an expansion of 49 people (2.0%). Such variation is deduced using the ABS estimated resident population count of 2,520 as of June 2025 alongside 12 validated new addresses recorded post-Census. Consequently, the local density settles at 19.4 persons per square kilometer, ensuring generous living space for community members. Net overseas migration served as the primary demographic catalyst, accounting for roughly 88.5% of total net additions across recent tracking intervals.

Projections compiled by the ABS and Geoscience Australia, published in 2024 using 2022 as their baseline, are utilized by AreaSearch across SA2 locations. In instances lacking coverage or extending beyond 2032, figures rely on the SA State Government's 2023 age-specific Regional/LGA releases (anchored to 2021 numbers), applying weighted aggregation from LGA down to SA2 zones. Looking ahead, future population trajectories place the location within the top quartile nationwide, anticipating an influx of 627 persons by 2041 according to recent annual ERP data, which translates to a cumulative expansion of 24.8% across the 16 years.

Residential SupplyHousing Development & Building Approvals in One Tree Hill

Table Chart PROFILE FAQ

27 new dwellings have been approved in One Tree Hill over the past five years, an average of 5 a year. That is 2.2 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 authorisations in One Tree Hill have averaged roughly 5 new homes per annum, reaching an aggregate of 27 homes across the preceding 5 financial years. A balanced supply-demand dynamic has underpinned local market stability, evidenced by an average influx of 1.4 people annually for every residential unit constructed across the last 5 financial years (from FY-22 to FY-26). Concurrently, typical building approvals average $475,000 in expected construction cost, outperforming regional standards and highlighting a focus on premium builds. Non-residential activity remains subdued, with commercial approvals registering just $143,000 over the current financial year.

Residential building activity across One Tree Hill is remarkably quiet, tracking 88.0% below regional average per person relative to Greater Adelaide. Such restrained building output generally bolsters pricing leverage and buyer interest for established stock. This volume also trails countrywide levels, pointing toward potential planning restrictions and an established urban footprint. Furthermore, detached houses have accounted for every approved dwelling, preserving the traditional low-density suburban landscape oriented toward family buyers seeking room to move. A metric of 630 people per residential approval underscores the subdued, low-scale nature of local construction. Demographic forecasts from the most recent AreaSearch quarterly release project One Tree Hill expanding by 625 residents by 2041. Should current construction volumes persist, housing supply could fall short of demographic growth, creating upward pressure on prices and intensifying buyer competition.

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 — 12 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (2,473 at the 2021 Census → 2,522 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.

Cross-check us. The Census baseline for this boundary is at ABS 2021 Census QuickStats (402021033). QuickStats reports 2021 only — the figures on this page are more current wherever the ledger shows a later date.

Common questions about this page

Why can the One Tree Hill SA2 boundary differ from the suburb boundary?
This page uses ABS Statistical Area Level 2 (SA2) boundaries for statistical reporting (e.g., census and ERP). SA2 areas can differ materially from Suburbs and Localities (SAL) boundaries, even when they share similar names, because they are defined for different purposes and often use different geographic boundaries.
Where does the data on this One Tree Hill page come from?
AreaSearch compiles this page from official and industry sources — including ABS, Geoscience Australia, Valuer General, Provider directories, DEWR, JSA, State Transport Departments and ACARA — then aggregates them to the boundary shown and calculates the rankings, growth rates and benchmarks itself. Property sales come from the state valuation authority, rents from state rental bond lodgements, development applications from council and state planning portals, school data from ACARA, and public transport from state transport departments.
Is the One Tree Hill data on this page just from the 2021 Census?
No. Most of this page is maintained well beyond the Census. Sourced entirely from current releases: development & approvals (Aug 2026), property sales & rents (Sep 2026), infrastructure projects (Jun 2026) and services & amenities (Jul 2026). Built on a Census baseline but carrying newer measures on top: population (to Aug 2026), age profile (to Aug 2026), employment (to Mar 2026), income (to FY 2023), education (to Aug 2026), transport (to Jul 2026) and health (to 2024). Population and age cohorts in particular are re-based to the latest ABS Estimated Resident Population rather than left at 2021 counts. Only housing, households and cultural diversity remain wholly Census-based, because no more current small-area dataset exists for those measures.
