Population
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 the suburb of Londonderry (NSW) is estimated at around 4,079 as of May 2026. This reflects an increase of 55 people since the 2021 Census, which reported a population of 4,024 people. The change is inferred from the resident population of 4,074 estimated by AreaSearch following examination of the latest ERP data release by the ABS in June 2025 and an additional 8 validated new addresses since the Census date. This level of population equates to a density ratio of 112 persons per square kilometer. Natural growth contributed approximately 62.0% of overall population gains 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 applied to all areas for years 2032 to 2041. Future population trends project an above median growth, with the suburb expected to increase by 534 persons to 2041 based on aggregated SA2-level projections, reflecting a total increase of 13.0% over the 16 years.

Development
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 approximately four residential properties granted approval per year over the past five financial years. This totals an estimated 24 homes from FY-21 to FY-25. So far in FY-26, two approvals have been recorded. On average, about two people moved to the area for each dwelling built during this period. However, recent data shows this has intensified to 11.4 people per dwelling over the past two financial years, indicating growing popularity and potential undersupply.
Development projects average $483,000 in construction value, suggesting a focus on premium properties. Additionally, $353,000 in commercial development approvals have been recorded this financial year, reflecting the area's residential nature. Compared to Greater Sydney, Londonderry records significantly lower building activity, at 74.0% below the regional average per person. This scarcity typically strengthens demand and prices for existing properties. Recent development has been entirely comprised of detached dwellings, maintaining the area's traditional low density character with a focus on family homes.
The estimated count of 819 people in the area per dwelling approval reflects its quiet, low activity development environment. Future projections show Londonderry adding approximately 529 residents by 2041, potentially leading to buyer competition and price increases if current development rates do not match population growth.

Western Sydney International (Nancy-Bird Walton) Airport
A transformational 24/7 curfew-free airport project on track to begin operations in 2026. As of May 2026, the project has entered the final phase of operational testing and certification. Cargo services are scheduled to launch in July 2026, with inaugural passenger flights set for October 2026. The facility features a single integrated terminal designed by Zaha Hadid and COX Architecture, a 3.7km runway, and a 5-star Green Star sustainability rating. It is designed to handle 10 million passengers annually at opening.
Sydney Metro - Western Sydney Airport
A 23-kilometre driverless metro railway connecting St Marys to the new Western Sydney International (Nancy-Bird Walton) Airport and Bradfield City Centre via twin tunnels and elevated viaducts. The line includes six new stations: St Marys (interchange with the T1 Western Line), Orchard Hills, Luddenham, Airport Business Park, Airport Terminal, and Bradfield. As of early 2026 the project is in advanced construction, with platform installation complete at Bradfield Station and progressing at Airport Business Park and Orchard Hills. Track laying is underway between Luddenham and St Marys, with more than 6,400 tonnes of Australian-made rail steel to be installed across the alignment by mid-2026. The Stations, Systems, Trains, Operations and Maintenance package is being delivered by the Parklife Metro consortium, which will operate and maintain the line for 15 years. Twelve three-car Siemens Inspiro driverless trains will run on the line. Passenger services were originally targeted for late 2026 to coincide with the airport opening on 26 October 2026, however government and contractor advice now indicates the line will open in mid-to-late 2027 (with April 2027 the earliest date publicly reported). A free interim WSI Link bus service between St Marys and the airport is running until the metro opens. The project is supporting more than 14,000 jobs during construction.
Rouse Hill Hospital
A $910 million state-of-the-art public hospital jointly funded by the NSW and Commonwealth Governments. The facility includes a full emergency department, 300+ beds, comprehensive birthing services, day surgery, and a digital-first approach to healthcare. Key features include a 'care arcade' for retail and cafes, multi-storey parking, and landscaped rooftop terraces for patients and staff.

Sydney Metro - Tallawong to St Marys Corridor (T2SM)
A protected passenger rail corridor of approximately 15km connecting the Tallawong Stabling Facility to St Marys Station, passing through Schofields Station and the Marsden Park growth area. The corridor preservation study is defining and protecting space for two potential rail services - a future extension of Sydney Metro North West terminating at Schofields, and a new metro-style service between Schofields and St Marys that would link with the Sydney Metro Western Sydney Airport line. The corridor was identified in the 2012 Long Term Transport Master Plan as one of Sydney's 19 major transport corridors requiring preservation. As of late 2025 the preferred corridor through Marsden Park has been protected, with land acquisition deferred until closer to construction. The link will provide interchange between Sydney's North West and South West growth areas and onward connections to the broader rail network.
North West Treatment Hub
Sydney Water's North West Treatment Hub is a 10-year, approximately 2 billion dollar program upgrading three water resource recovery facilities (WRRFs) at Castle Hill, Rouse Hill and Riverstone to support rapid growth across Sydney's north west. The program adds 45 megalitres per day of treatment capacity and is expected to service around 200,000 new home connections by 2056. Delivery is split into staged programs through the North West Hub Alliance (Sydney Water, John Holland, Stantec and KBR), with separate works at Castle Hill led by Abergeldie Complex Infrastructure and earlier Rouse Hill stages delivered by Fulton Hogan. Scheme 1 works at Rouse Hill and Riverstone (around 595 million dollars, awarded December 2023) are more than 50 percent complete and include a new biosolids handling plant, a membrane bioreactor system replacing ageing lagoons at Rouse Hill, and a new high voltage electrical feeder. Scheme 2 (around 295 to 300 million dollars, awarded December 2025) doubles Riverstone's liquids treatment capacity, adding a new liquid treatment stream, an underground effluent pipeline, and connection to the new Grantham Farm Zone Substation, with construction expected to start in March 2027 and run for around three years. Riverstone will also host NSW's first wastewater carbonisation facility, billed as the world's largest sewage sludge carbonisation plant, converting biosolids into biochar while breaking down PFAS. Castle Hill upgrades are expected to be completed in 2025. The program won the 2025 Sustainability Project of the Year award.
Tallawong to St Marys (T2SM) Passenger Rail Corridor
The Tallawong to St Marys (T2SM) Corridor is a planned passenger rail link of approximately 15 kilometres connecting Sydney's North West and South West Growth Areas, with proposed stations at Schofields and serving the Marsden Park growth area. The corridor will define and protect land for two potential rail services: a future extension of Sydney Metro North West terminating at Schofields, and a new metro style service between Schofields and St Marys, providing an interchange with the Sydney Metro Western Sydney Airport line. Identified in the Long Term Transport Master Plan 2012 as one of Sydney's 19 major transport corridors requiring preservation, the preferred corridor from Tallawong through Marsden Park has been protected for future transport infrastructure. In March 2026 the proposed north-south rail link, which includes the T2SM corridor, was added to Infrastructure Australia's 2026 Infrastructure Priority List as a potential investment opportunity within the 2 to 4 year pipeline. Final business case work is being progressed, with land acquisition not required until closer to the time the infrastructure is delivered.
