Londonderry (NSW)

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

The population of Londonderry NSW, as estimated by AreaSearch using ABS updates and new addresses validated since the Census, is approximately 4,122 as of Nov 2025. This figure represents an increase of 98 people (2.4%) from the 2021 Census count of 4,024 residents. The estimated resident population used for this calculation was 4,109, derived by AreaSearch after examining ABS's latest ERP data release in June 2024 and considering an additional 9 validated new addresses since the Census date. This results in a population density ratio of 113 persons per square kilometer. Since the Census, Londonderry's growth rate of 2.4% is within 2.2 percentage points of the SA3 area (4.6%), indicating strong growth fundamentals. Natural growth contributed approximately 62.0% to overall population gains during recent periods in the suburb.

AreaSearch uses 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 the years 2032 to 2041. By 2041, an above median population growth is projected nationally, with Londonderry expected to increase by 532 persons, reflecting a total increase of 13.2% over the 17-year period.

AreaSearch assessment of residential development drivers sees a low level of activity in Londonderry, 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, Londonderry has recorded around 5 residential properties granted approval per year over the past five financial years, totalling an estimated 26 homes. So far in FY-26, 3 approvals have been recorded. With an average of 1.4 people moving to the area for each dwelling built between FY-21 and FY-25, supply and demand appear well-balanced, creating stable market conditions. However, recent data shows this has intensified to 14.2 people per dwelling over the past two financial years, indicating growing popularity and potential undersupply. Development projects average $483,000 in construction value, aligned with broader regional development.

Additionally, $275,000 in commercial development approvals have been recorded this financial year, demonstrating the area's residential nature. Compared to Greater Sydney, Londonderry records markedly lower building activity, 72.0% below the regional average per person, which typically strengthens demand and prices for existing properties. This activity is likewise lower than nationally, reflecting market maturity and possible development constraints. Recent development has been entirely comprised of detached dwellings, maintaining the area's traditional low density character with a focus on family homes appealing to those seeking space. The estimated count of 1029 people in the area per dwelling approval reflects its quiet, low activity development environment.

Future projections show Londonderry adding 546 residents by 2041 (from the latest AreaSearch quarterly estimate). At current development rates, housing supply may struggle to match population growth, potentially heightening buyer competition and supporting price increases.

The employment environment in Londonderry shows above-average strength when compared nationally

Londonderry has a balanced workforce with both white and blue collar jobs. The construction sector is prominent, with an unemployment rate of 2.9%.

As of June 2025, 2,319 residents are employed, which is 1.3% below Greater Sydney's rate of 4.2%. Workforce participation stands at 63.1%, compared to Greater Sydney's 60.0%. Key employment industries include construction, health care & social assistance, and retail trade. Construction is particularly strong, with an employment share 2.3 times the regional level.

However, professional & technical jobs are under-represented at 3.6% compared to Greater Sydney's 11.5%. Employment opportunities locally appear limited, as shown by a decrease in labour force (-2.4%) and employment (-2.6%) over one year, leading to an unemployment rate rise of 0.2 percentage points. In contrast, Greater Sydney saw employment growth of 2.6% and labour force growth of 2.9%, with an unemployment rate rise of 0.3 percentage points. Jobs and Skills Australia's national employment forecasts from Sep-22 project national employment growth at 6.6% over five years and 13.7% over ten years. Applying these projections to Londonderry's employment mix suggests local employment should increase by 5.8% over five years and 12.1% over ten years, though this is a simple extrapolation for illustrative purposes only.
