Lockleys

Population growth drivers in Lockleys are slightly above average based on AreaSearch's ranking of recent, and medium term trends

Based on analysis of ABS population updates for the broader area, the estimated population of the suburb of Lockleys as of May 2026 is around 6,099. This reflects an increase of 112 people since the 2021 Census, which reported a population of 5,987 people. The change is inferred from the resident population of 6,097 estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2025 and an additional 35 validated new addresses since the Census date. This level of population equates to a density ratio of 1,924 persons per square kilometer, which is above the average seen across national locations assessed by AreaSearch. Population growth for the area was primarily driven by overseas migration that contributed approximately 89.0% of overall population gains during recent periods.

AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data and years post-2032, the SA State Government's Regional/LGA projections by age category are adopted, released in 2023 and based on 2021 data, with adjustments made employing a method of weighted aggregation of population growth from LGA to SA2 levels. Looking at population projections moving forward, an above median population growth is projected for the suburb of Lockleys, with an expected increase of 1,036 persons to 2041 based on aggregated SA2-level projections, reflecting a total increase of 16.9% over the 16 years.

As of December 2025, 3,381 residents are employed while the unemployment rate is 2.5 percentage points lower than Greater Adelaide's rate of 3.8%.

Workforce participation in Lockleys is broadly similar to Greater Adelaide's 66.0%.

Finance & insurance has a particularly high employment share at 1.5 times the regional level, while accommodation & food employs just 5.0% of local workers compared to Greater Adelaide's 6.8%.

The predominantly residential area appears to offer limited local employment opportunities based on Census data. Over the 12 months to December 2025, employment increased by 5.1% and labour force increased by 4.5%, causing a fall in unemployment rate of 0.5 percentage points (AreaSearch analysis of SALM and ABS data). In comparison, Greater Adelaide saw employment grow by 4.2%, labour force expand by 3.9%, and unemployment fall by 0.3 percentage points. Jobs and Skills Australia's national employment forecasts from May-25 project a 6.6% increase over five years and 13.7% over ten years for national employment. Applying these projections to Lockleys' employment mix suggests local employment should increase by 6.7% over five years and 13.8% over ten years, though this is a simple weighting extrapolation for illustrative purposes and does not account for localised population projections.
