Londonderry (NSW)

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

Based on analysis of ABS population updates for the broader area, and new addresses validated by AreaSearch since the Census, Londonderry's population is estimated at around 4175 as of Nov 2025. This reflects an increase of 151 people (3.8%) since the 2021 Census, which reported a population of 4024 people. The change is inferred from the resident population of 4114, estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2024 and an additional 9 validated new addresses since the Census date. This level of population equates to a density ratio of 115 persons per square kilometer. Londonderry's growth positions it within 0.8 percentage points of the SA3 area, demonstrating competitive growth fundamentals. Population growth for the area was primarily driven by natural growth that contributed approximately 62% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data, AreaSearch utilises NSW State Government's SA2 level projections released in 2022 with a base year of 2021. Growth rates by age group are applied to all areas for years 2032 to 2041. Future population trends project an above median growth, with the area expected to increase by 531 persons to 2041 based on aggregated SA2-level projections, reflecting a total increase of 11.8% over the 17 years.

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

Londonderry recorded approximately 4 residential properties granted approval per year over the past 5 financial years ending FY-25. This totals an estimated 23 homes. In FY-26 so far, 2 approvals have been recorded. On average, 1.6 people moved to the area annually for each dwelling built between FY-21 and FY-25, indicating balanced supply and demand. However, this figure intensified to 11.4 people per dwelling over the past 2 financial years, suggesting growing popularity and potential undersupply.

Development projects averaged $483,000 in construction value during this period, reflecting a focus on premium segment properties. In FY-26, $353,000 in commercial development approvals have been recorded, highlighting the area's residential nature. Compared to Greater Sydney, Londonderry has markedly lower building activity, with 75.0% below the regional average per person. This scarcity typically strengthens demand and prices for existing properties. Recent development comprised entirely of detached dwellings maintained the area's traditional low density character, appealing to those seeking space.

The estimated count of 823 people in the area per dwelling approval reflects its quiet, low activity development environment. Future projections show Londonderry adding 492 residents by 2041, potentially heightening buyer competition and supporting price increases if current development rates do not match population growth.

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 notably prominent.

As of September 2025, the unemployment rate was 2.8%. This is lower than Greater Sydney's rate of 4.2%, with Londonderry's workforce participation at 63.1% compared to Greater Sydney's 60.0%. Leading employment industries include construction, health care & social assistance, and retail trade. Construction stands out with an employment share 2.3 times the regional level.

However, professional & technical services are under-represented, at 3.6% versus Greater Sydney's 11.5%. In a 12-month period ending in September 2025, Londonderry's labour force decreased by 3.9%, while employment decreased by 3.8%. This resulted in an unemployment rate drop of 0.1 percentage points. In contrast, Greater Sydney saw employment growth of 2.1% and labour force growth of 2.4%, with a 0.2 percentage point rise in unemployment. As of 25-Nov-25, NSW employment contracted by 0.03%, losing 2,260 jobs, with the state unemployment rate at 3.9%. Nationally, the unemployment rate was 4.3%. Jobs and Skills Australia's national employment forecasts from May-25 project a 6.6% increase over five years and 13.7% over ten years. Applying these projections to Londonderry's employment mix suggests local employment could grow by 5.8% in five years and 12.1% in ten years, though this is a simplified extrapolation for illustrative purposes only.
