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

Based on ABS population updates and AreaSearch validation, as of Nov 2025, Largs Bay's estimated population is around 4,208. This reflects a 104-person increase from the 2021 Census figure of 4,104. The change is inferred from AreaSearch's estimate of 4,184 residents in Jun 2024 and seven new addresses since the Census date. This results in a population density ratio of 2,023 persons per square kilometer, above national averages assessed by AreaSearch. Overseas migration contributed approximately 69% to recent population gains, with all migration drivers being positive factors.

ABS/Geoscience Australia projections for each SA2 area are adopted, released in Jun 2024 with a base year of 2022. For areas not covered and years post-2032, South Australian Government's Regional/LGA projections by age category are used, adjusted employing weighted aggregation from LGA to SA2 levels. By 2041, the Largs Bay area is expected to increase by approximately 400 persons, reflecting a 12.8% total increase over the 17 years based on aggregated SA2-level projections.

Residential development activity is slightly higher than average within Largs Bay when compared nationally

Between fiscal years 2021 and 2025, Largs Bay had approximately 52 residential building approvals. In the current financial year 2026, there have been 5 approvals so far. On average, around 3.5 people moved to the area for each dwelling built over these five years.

This indicates a significant imbalance between demand and supply in the housing market of Largs Bay. The average construction cost value for new properties is $419,000, suggesting that developers are targeting the premium market segment with higher-end properties. In terms of commercial development, there have been $1.2 million worth of approvals recorded this financial year. This indicates minimal commercial development activity in Largs Bay compared to Greater Adelaide, where it is 71.0% below the regional average per person. The scarcity of new properties typically strengthens demand and prices for existing properties. Recent construction activity in Largs Bay comprises 23.0% detached dwellings and 77.0% attached dwellings. This trend towards denser development provides accessible entry options, appealing to downsizers, investors, and entry-level buyers.

This represents a notable shift from the area's existing housing composition, which is currently 83.0% houses. Largs Bay reflects a low density area with approximately 246 people per approval. According to the latest AreaSearch quarterly estimate, Largs Bay is expected to grow by 537 residents through to 2041. If current development rates continue, housing supply may struggle to match population growth, potentially heightening buyer competition and supporting price increases in the area.
