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.

Lockleys has an estimated 14,343 residents, up from 13,452 at the 2021 Census — a change of 891 people, or 6.6%. Growth has averaged 1.0% a year over five years. Overseas migration accounts for 96.3% of that increase. That puts 2,516 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
According to evaluation by AreaSearch, the resident count of Lockleys stands at approximately 14,343 as of Aug 2026. This represents an expansion of 891 people (6.6%) relative to the 2021 Census, when 13,452 people were recorded. Such movement is calculated from the ABS estimated resident population figure of 14,336 as of June 2025 alongside 83 validated new addresses identified following the Census. This headcount generates a population density of 2,516 persons per square kilometer, placing the locality in the top quartile of assessed Australian regions. The post-census gain of 6.6% in Lockleys trails the state benchmark (7.7%) by only 1.1 percentage points, highlighting solid underlying demographic momentum.
Net overseas arrivals served as the primary growth catalyst, generating roughly 96.3% of total population additions over recent intervals. Projections compiled by Geoscience Australia and the ABS from 2024 (anchored to a 2022 baseline) are applied to individual SA2 zones. For periods beyond 2032 or locations absent from that release, projections published in 2023 by the SA State Government by age group using 2021 baselines are utilized, applying weighted aggregation methods to translate LGA growth to the SA2 level. Driven by overarching demographic patterns, long-term expansion is forecast to outpace national median rates, with Lockleys projected to add 1,954 persons by 2041 according to recent annual ERP data, yielding an overall increase of 13.6% over the 16 years.
Frequently Asked Questions - Population
367 new dwellings have been approved in Lockleys over the past five years, an average of 73 a year. That places the area in the 74th percentile for residential development activity nationally, about 5 approvals per 1,000 residents a year. Of the 73 dwellings approved in the latest reporting year, 68% were detached houses and the rest townhouses or apartments. 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 Lockleys have averaged approximately 73 dwellings each year, totaling 367 homes permitted across the past 5 financial years (between FY-22 and FY-26). Local supply appears balanced against incoming demand, with 1.9 new residents arriving per approved residence over the past 5 financial years (between FY-22 and FY-26). Furthermore, building applications reflect an average construction cost of $447,000 per dwelling, coming in slightly above regional norms and pointing to higher-end residential development. In addition, $34.7 million worth of commercial approvals have been registered during this financial year, illustrating robust non-residential activity.
On a per-capita basis, building approvals in Lockleys track 19.0% below Greater Adelaide levels, placing the area in the 72nd percentile across Australia. Detached housing accounted for 68.0% of recent construction while attached formats represented 32.0%, reflecting a growing distribution of higher-density dwellings that accommodate diverse budgets, ranging from compact starter choices to larger residences. With roughly 163 people per approved dwelling, the suburb exhibits the characteristics of an expanding market. Demographic projections indicate that Lockleys will expand by 1,947 residents by 2041 relative to the newest AreaSearch quarterly estimate. Current construction trajectories appear well calibrated to meet upcoming demand, supporting orderly market conditions without triggering sharp cost escalation.

8,421 residents of Lockleys are employed, from a labour force of 8,603. Unemployment sits at 2.1%, with participation at 71.1%. Weighted for its industry mix, the area's sectors are forecast to grow about 6.7% nationally over five years. That reflects industry composition only and makes no allowance for local population growth. The working-day population is estimated at 12,557, 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
Lockleys features an educated workforce with considerable participation across essential services, an unemployment level of only 2.1%, and annual employment growth estimated at 7.0%. There were 8,421 employed locals as of March 2026, while the local jobless rate sits 1.7% below the Greater Adelaide benchmark of 3.8%. Labor force participation stands at 71.1%, compared to 66.4% across Greater Adelaide. Census figures showed that merely 11.0% of local workers operated from home, though potential distortion from Covid-19 restrictions should be recognized. Local workforce participation is concentrated within education & training, health care & social assistance, and retail trade.
Conversely, manufacturing employs a modest share of the local workforce at 5.8%, falling short of the 7.0% recorded across Greater Adelaide. The predominantly residential layout generates fewer local positions, as evidenced by the imbalance between resident workers and local job counts at the Census. Analysis of ABS and SALM figures indicates that annual local employment expanded by 7.0% while the labor pool grew by 6.0%, lowering local unemployment by 0.9 percentage points. This surpassed Greater Adelaide, where employment rose by 4.2%, the labor base expanded by 4.0%, and unemployment contracted by 0.2 percentage points. Broader trends from Jobs and Skills Australia national projections issued in Mar-26 provide additional context on future demand across Lockleys. When these five-year and ten-year nationwide forecasts (which anticipate overall Australian job growth of 6.6% over five years and 13.7% over ten years) are applied to the local industry profile, employment for Lockleys is projected to expand by 6.7% over five years and 13.9% over ten years. This calculation represents an illustrative weighted extrapolation that does not account for localized population growth.

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 — 83 validated new addresses here. The headline figure is therefore a current estimate for Aug 2026, not a 2021 count (13,452 at the 2021 Census → 14,343 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.
