Londonderry
A $1.8 million median house price on a rural-fringe lot area of 36.25 square kilometres might be the most striking signal about Londonderry: land here is priced well above what the headline density of 111 residents per square kilometre would suggest. Household income sits in the 82nd percentile nationally, yet the education-occupation index (IEO) falls to decile 2, meaning residents earn well relative to their formal qualifications. The suburb is 96.5% separate houses, with 57.7% of dwellings having four or more bedrooms, ratios that rank among the highest in the region. Low overseas-born share (15.1%, which is 6.5 points below national) and an 85.5% residential stability rate point to a long-settled, predominantly Anglo-Celtic community with very limited turnover.

The median house price of $1.8 million represents a 22.1% rise from $1,515,000 in 2024 to $1,850,000 in 2025, a sharp single-year jump. Monthly mortgage repayments average $2,400, and the mortgage-to-income ratio sits at 25.7%, below the 30% stress threshold despite prices well above state average. The stock is almost entirely separate houses (96.5%), with 57.7% having four or more bedrooms, so buyers get substantial space compared to most Sydney fringe markets. Only 1.6% of dwellings are apartments. The outright-ownership rate of 37.7% is high, meaning a significant share of the community holds property debt-free, which tends to suppress forced-sale risk. With just 22.0% renters, competition for owner-occupier stock is concentrated.

For Investors
Londonderry's investment profile is driven by capital growth rather than yield. Weekly rent averages $460, which against an $1.8 million median implies a gross yield of roughly 1.3%, low by Western Sydney standards. The vacancy rate sits at 3.8%, above the 2% to 3% equilibrium range, signalling modest oversupply in the rental pool. The renter share of 22.0% is smaller than most investor-targeted suburbs, limiting tenant depth. On the growth side, house prices rose 22.1% in one year from 2024 to 2025, the strongest short-term signal in the data. Development activity recorded 37 applications in the past 12 months, mostly dwelling additions and new houses, pointing to incremental infill rather than high-density supply that would dilute existing values.

Demographics
The median age of 38 is 2 years below the national figure, reflecting a younger-than-average owner-occupier base. Overseas-born residents make up 15.1%, which is 6.5 percentage points below the national rate, consistent with the Anglo-Celtic ancestry profile: English (1,310 people) is the largest group, followed by Maltese (665), a distinct community concentration not common across broader Western Sydney. Average household size of 3.3 is 0.8 above the national average, driven by the prevalence of couples with children (1,339 families) relative to couples without children (711). University qualifications reach only 14.1%, which is 16 percentage points below the national rate, a gap that partly explains the IEO decile 2 score despite above-average incomes.

Tenure
Londonderry's housing market is overwhelmingly owner-occupier and detached. Separate houses account for 96.5% of stock, compared to the national average where medium and high density represent a far larger share. Four-plus bedroom homes make up 57.7% of dwellings, with three-bedroom at 31.8%, leaving very little in the small-dwelling segment. Tenure splits to 37.7% owned outright, 40.3% under mortgage, and 22.0% renting, meaning over three-quarters of the population has an ownership interest. The median house price rose from $1,515,000 in 2024 to $1,850,000 in 2025, a 22.1% CAGR over the measured period. Mortgage-to-income at 25.7% and rent-to-income at 21.3% both sit below stress thresholds, giving the market a degree of financial resilience unusual at this price point.

Economy & Employment
Construction dominates local employment at 21.6% of the workforce (241 people), well above the national industry share, which connects to the suburb's large-lot residential character and ongoing dwelling approvals. Healthcare follows at 11.0% (123 people) and Education at 8.7% (97), reflecting broader Western Sydney service employment patterns. By occupation, Clerical/Admin (307) and Machinery/Drivers (295) lead, with Managers third at 251. Unemployment is 3.7% and the full-time employment rate is 63.4%, both close to national benchmarks. The SEIFA IRSD decile of 6 places Londonderry at moderate advantage nationally, while the IER decile of 9 signals strong economic resources, a divergence explained by high homeownership rates and larger lot sizes inflating asset values above what occupation and education scores alone would predict.

Transport to Work
Car dependency is pronounced: 88.8% of residents drive to work, and public transport use is just 1.1%, compared to the Sydney metropolitan average that sits well above 20%. The large 36.25 square kilometre area means distances between destinations are substantial, making active transport impractical for most trips despite a 4.8% walk-or-cycle rate. No schools are recorded within the suburb boundary in the dataset. The IRSAD decile of 5 places Londonderry at the national median for combined advantage and disadvantage. Volunteering runs at 9.2% and 5.2% of residents (197 people) need daily assistance, both modest figures. The development count of 37 applications in 12 months shows ongoing housing activity that will gradually add infrastructure pressure to existing road and service networks.

Is Londonderry good for property investment?
Capital growth is the primary investment case: prices rose 22.1% in one year to $1,850,000 in 2025. However, weekly rent of $460 against an $1.8 million median implies a gross yield of roughly 1.3%, very low. The vacancy rate is 3.8%, above the 2%-3% equilibrium range, and the renter pool is a thin 22.0% of households.
How is Londonderry's population changing?
The current population is 4,024 across 36.25 square kilometres. Residential stability is high at 85.5%, meaning turnover is just 14.5% per year. The median age of 38 is 2 years below the national figure, and average household size of 3.3 is 0.8 above national, suggesting a settled family-oriented community rather than one experiencing rapid demographic change.
How much development is happening in Londonderry?
There were 37 development applications lodged in the past 12 months. Recent examples include new dwelling houses, deck and balcony additions, and complying development certificates for sheds. This level of activity is modest for a 36.25 square kilometre suburb, pointing to steady infill rather than large-scale subdivision or unit development.
How to read these comparisons
Phrases like "above the national average" reference the unweighted median across Australian suburbs with more than 1,000 residents, not population-weighted national figures. Suburb-level medians are more useful for ranking suburbs against each other; ABS census headlines are population-weighted (so dominated by Sydney and Melbourne) and can read very differently.
Current baseline (refreshed 2026-05-10): median age 40, university-educated 30.1%, born overseas 21.6%, average household size 2.5 people.
Data sources: ABS 2021 Census (demographics, income, tenure), state Valuer-General (house prices), Department of Jobs SALM (unemployment), ACARA (school ICSEA), state Crime Statistics agencies (offences), council DA portals (development applications). Population forecasts use a Hamilton-Perry cohort model calibrated to ABS ERP.
