South Turramurra

An assessment of population growth drivers in South Turramurra reveals an overall ranking slightly below national averages considering recent, and medium term trends

The population of South Turramurra, based on analysis of ABS updates and AreaSearch validations, is estimated to be around 3,272 as of November 2025. This reflects an increase from the 2021 Census figure of 3,208 people, a rise of 64 individuals (2.0%). The current resident population estimate of 3,267 is inferred by AreaSearch following examination of the latest ERP data release by the ABS in June 2024 and address validation since the Census date. This results in a density ratio of 1,069 persons per square kilometer. South Turramurra's growth rate since the census (2.0%) is within 2.4 percentage points of the SA3 area's growth rate (4.4%), indicating competitive growth fundamentals. Overseas migration was the primary driver of population gains in recent periods for the suburb.

AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022, and NSW State Government's SA2 level projections for areas not covered by this data, released in 2022 with a base year of 2021. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. According to these projections, the suburb's population is expected to decline by 44 persons by 2041, while specific age cohorts like the 75 to 84 age group are projected to grow by 89 people over this period.

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

South Turramurra averaged approximately four new dwelling approvals per year based on AreaSearch analysis of ABS building approval numbers. Between financial years 2021 (FY-21) and 2025 (FY-25), around twenty homes were approved, with none yet recorded in FY-26.

This resulted in an average of 3.2 people moving to the area per year for each dwelling built over these five years. This demand significantly outpaced supply, likely exerting upward pressure on prices and intensifying competition among buyers. Developers focused on the premium market, with new properties constructed at an average value of $791,000. Compared to Greater Sydney, South Turramurra had notably less development activity, 68.0% below the regional average per person as of recent data. This limited new supply generally supports stronger demand and values for established dwellings. However, construction activity has recently intensified in the area. South Turramurra's new building activity showed 40.0% detached houses and 60.0% townhouses or apartments, marking a significant shift from the current housing pattern of 99.0% houses.

This skew towards compact living offers affordable entry pathways, attracting downsizers, investors, and first-time purchasers. The location had approximately 328 people per dwelling approval, indicating a low density market. With population expected to remain stable or decline, South Turramurra should see reduced pressure on housing in the future, potentially creating opportunities for buyers.
