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

As per analysis of ABS population updates for the broader area, and new addresses validated by AreaSearch, the population of South Turramurra is estimated to be around 3,169 as of May 2026. This reflects a decrease of 39 people (1.2%) since the 2021 Census, which reported a population of 3,208 people. The change is inferred from the resident population of 3,169, estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2025 and address validation since the Census date. This level of population equates to a density ratio of 1,035 persons per square kilometer, which is relatively in line with averages seen across locations assessed by AreaSearch. Population growth for the suburb was primarily driven by overseas migration during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with 2022 as the base year. For any SA2 areas not covered by this data, AreaSearch is utilising the NSW State Government's SA2 level projections, as released in 2022 with 2021 as the base year. Growth rates by age group from these aggregations are also applied to all areas for years 2032 to 2041. According to this methodology, projections indicate a decline in overall population over this period, with the suburb's population expected to shrink by 34 persons by 2041. However, growth across specific age cohorts is anticipated, led by the 75 to 84 age group, which is projected to grow by 61 people.

AreaSearch assessment of residential development drivers sees a low level of activity in South Turramurra, placing the area among the bottom 25% of areas assessed nationally

Based on AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, South Turramurra has averaged around 5 new dwelling approvals per year. An estimated 25 homes were approved over the past 5 financial years, between FY-21 and FY-25, with 1 more approved so far in FY-26.

On average, 1.3 people have moved to the area for each dwelling built during these years. This suggests balanced supply and demand, maintaining stable market conditions. New properties are constructed at an average value of $791,000, indicating a focus on premium developments. Compared to Greater Sydney, South Turramurra has significantly less development activity, 59.0% below the regional average per person. This limited new supply generally supports stronger demand and values for established dwellings. However, construction activity has intensified recently. This is also under the national average, suggesting the area's established nature and potential planning limitations.

New building activity shows an equal split between detached houses (50.0%) and townhouses or apartments (50.0%). This shift from the current 99.0% houses suggests diminishing developable land availability and responses to evolving lifestyle preferences and housing affordability needs. South Turramurra has approximately 383 people per dwelling approval, reflecting an established area with a stable or declining population. This should reduce pressure on housing, potentially creating opportunities for buyers.

AreaSearch analysis places South Turramurra well above average for employment performance across multiple indicators

South Turramurra has a highly educated workforce with strong representation in the technology sector. Its unemployment rate was 3.0% as of December 2025, with an estimated employment growth of 1.2% over the past year, according to AreaSearch's statistical area data aggregation. As of that date, 1717 residents were employed while the unemployment rate was 1.2 percentage points lower than Greater Sydney's rate of 4.2%.

Workforce participation in South Turramurra was broadly similar to Greater Sydney's at 68.8%. However, it is important to consider Covid-19 lockdown impacts on work from home figures, which were high at 62.3% based on Census responses. The key industries of employment among residents are professional & technical, health care & social assistance, and education & training. South Turramurra shows particular specialization in professional & technical services with an employment share of 140% compared to the regional level.

Meanwhile, construction has limited presence with 5.3% employment compared to the regional average of 8.6%. The area appears to offer limited local employment opportunities as indicated by the count of Census working population versus resident population. Over the year to December 2025, employment increased by 1.2% while labour force increased by 1.4%, resulting in a slight rise in unemployment by 0.2 percentage points. In contrast, Greater Sydney experienced higher employment growth at 2.2% and labour force growth at 2.3%. Jobs and Skills Australia's national employment forecasts from May-25 offer insights into potential future demand within South Turramurra. These projections estimate that national employment should increase by 6.6% over five years and 13.7% over ten years. However, applying these industry-specific projections to South Turramurra's employment mix suggests local employment could increase by 7.4% over five years and 14.8% over ten years, though these are simple weighted extrapolations for illustrative purposes and do not account for localized population projections.
