Largs Bay

Largs Bay is positioned among the lower quartile of areas assessed nationally for population growth based on AreaSearch's assessment of recent, and medium term trends

As of November 2025, the estimated population of Largs Bay is around 4,212. This figure reflects an increase of 108 people since the 2021 Census, which reported a population of 4,104. The change is inferred from AreaSearch's estimation of the resident population as 4,194 following examination of ABS ERP data released in June 2024, along with an additional seven validated new addresses since the Census date. This results in a population density ratio of 2,025 persons per square kilometer, higher than the average seen across national locations assessed by AreaSearch. Population growth was primarily driven by overseas migration contributing approximately 69% of overall population gains during recent periods.

ABS/Geoscience Australia projections for each SA2 area are adopted by AreaSearch, released in 2024 with a base year of 2022. For areas not covered and years post-2032, SA State Government's Regional/LGA projections based on 2021 data are used with adjustments made employing weighted aggregation methods from LGA to SA2 levels. Based on aggregated SA2-level projections, the suburb is expected to increase by approximately 400 persons by 2041, reflecting a total increase of around 12.7% over the 17-year period.

Residential development activity is lower than average in Largs Bay according to AreaSearch's national comparison of local real estate markets

Based on AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, Largs Bay has seen around 10 new homes approved each year. Over the past five financial years, from FY-21 to FY-25, approximately 51 homes were approved, with an additional 12 approved so far in FY-26.

This results in an average of about 3.5 people moving to the area for each dwelling built over these years. Consequently, demand significantly outpaces supply, typically putting upward pressure on prices and increasing competition among buyers. New properties are constructed at an average expected cost value of $419,000. Compared to Greater Adelaide, Largs Bay shows substantially reduced construction activity, with 71.0% below the regional average per person. This constrained new construction usually reinforces demand and pricing for existing properties. Recent construction comprises 33.0% detached dwellings and 67.0% townhouses or apartments, reflecting a shift towards higher-density living to create more affordable entry points and suit downsizers, investors, and first-home buyers. The location has approximately 662 people per dwelling approval, indicating an established market.

Future projections show Largs Bay adding 533 residents by 2041, based on the latest AreaSearch quarterly estimate. If current development rates continue, housing supply may not keep pace with population growth, potentially increasing competition among buyers and supporting stronger price growth.
