Harrington Park
Household income places Harrington Park at the 97.3rd percentile nationally, while its median age of 35 is 5 years below the national figure. The suburb houses 13,332 people across 8.0 square kilometres, and 92.8% of dwellings have four or more bedrooms. That combination points to a high-income, family-focused mortgage belt rather than a compact apartment market. Compared with nearby Narellan and Oran Park, its 98.0% separate-house share gives the suburb a more uniform detached-home profile, while an average household size of 3.5 is 1.0 person above the national average. English, Italian and Irish ancestries are prominent, and the 80.6% stay rate suggests established household ties.

Mortgage repayments are $2,708 monthly, while mortgage costs equal 20.7% of household income. The 60.9% mortgage tenure share is higher than the 25.5% owned-outright share, showing that most owner-occupiers are still paying down debt. Because 92.8% of dwellings have four or more bedrooms and 98.0% are separate houses, demand is concentrated in larger family homes rather than apartments. Compared with more mixed housing around Camden, this profile suits buyers prioritising land, storage and family space, although the 8.0 square kilometre suburb has a density of 1,665.6 people per square kilometre. The median age of 35 and household size of 3.5 reinforce that family orientation.

The median age of 35 and household size of 3.5 reinforce that family orientation.
For Investors
Investor conditions are shaped by a small rental pool and limited vacancy. The 13.1% renter share is lower than the 60.9% mortgage share, so Harrington Park is primarily an owner-occupier market rather than a high-turnover rental precinct. A weekly rent of $550 and a 1.6% vacancy rate point to tenant demand, but gross yield cannot be judged without a current purchase price. The annual forecast trend of 2.27%, driven by overseas migration, provides a growth signal. At the same time, 71 development applications over 12 months could expand local supply and create competition between established properties and newer homes. Compared with suburbs with larger rental pools, investors may find less depth but potentially steadier family-oriented demand.

Transport to Work
Daily travel is strongly car-oriented. About 55.5% of residents drive to work, compared with 0.6% using public transport and 0.6% walking or cycling, so private vehicle access is more important than transit or active travel. Work-from-home participation is 39.5%, which can reduce commuting frequency because a sizeable share of workers do not travel every weekday. Harrington Park has 1 local government primary school, Harrington Park Public School, giving families a local primary option; exact enrolment zones should be checked against the address because boundaries can differ from suburb lines and nearby Narellan or Oran Park. IRSAD is in decile 9 and economic resources in decile 10, both above lower-decile areas, while volunteering is 10.5%. For street-level safety decisions, check current NSW Police information because conditions can vary between streets.

Population Forecast
+2.27%/yr
(+258 people/yr)
EstablishedThe growth outlook is positive but changing in character. The annual trend is 2.27%, with overseas migration identified as the primary driver, so demand is being supported by population inflows rather than only household turnover. Population change across the wider area is 47.2% over 10 years, higher than zero and consistent with a substantial expansion phase. However, the trajectory is labelled Aging: the young share is down 5.0 percentage points, the working share is down 2.0 points and the senior share is up 3.5 points. Gentrification is not the current story, with a score of 15 and a stage of Not gentrifying; the shift measure also records a score of 3 at the same stage. Compared with a renewal-led suburb, Harrington Park is growing while its existing population profile gradually matures.

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 education open registers (school locations), state Crime Statistics agencies (offences), council DA portals (development applications). Population forecasts use a Hamilton-Perry cohort model calibrated to ABS ERP.
