Erskine Park
Almost the entire housing stock here is detached: 98.3% of dwellings are separate houses and just 0.5% are apartments, an unusually pure profile for a Sydney suburb. That shapes everything else. Household income sits in the 89.2nd percentile nationally, yet the SEIFA picture is mixed, with economic resources (IER) in decile 9 but education and occupation (IEO) only in decile 4. The median age of 37 runs 3.0 years below national, and average household size of 3.2 is 0.7 above national, both pointing to a family-dominated suburb. The median house price is $1,150,000, and population is edging down at 0.53% a year from 6,486 residents.

Buyers here are almost always buying a house, not a unit: 98.3% of dwellings are separate houses and 59.6% have four or more bedrooms, with another 37.1% offering three. The median house price of $1,150,000 rose 7.8% from $1,097,500 in 2024 to $1,183,000 in 2025, a single-year move that outpaces flat inner-city markets. Affordability is the strong point. Average monthly mortgage repayments of $2,167 produce a mortgage-to-income ratio of 21.3%, well below the 30% stress threshold, helped by household income in the 89.2nd percentile. That explains why 49.2% of households carry a mortgage while only 19.7% rent, a far higher owner-occupier tilt than apartment-heavy suburbs closer to the city.

For Investors
The renter pool is shallow at 19.7%, well below the share seen in apartment-dense suburbs, because 98.3% of stock is detached houses owners tend to hold. Weekly rent of $450 against the $1,150,000 median implies a gross yield near 2%, modest, though rent grew 28.6% over the period, which supports income returns over time. The 2.8% vacancy rate is tight and signals steady tenant demand rather than oversupply. Demand drivers are thin: net overseas migration adds 31 residents a year but internal migration removes 101, and annual population growth is negative at 0.53%. Development is active at 67 applications in 12 months, but the samples skew to industrial and single dwelling-house works rather than new rental supply, so the investment case leans on capital growth and rent escalation more than yield.

Demographics
The median age of 37 is 3.0 years below national, and average household size of 3.2 sits 0.7 above national, a combination that marks this as a family suburb rather than a singles or downsizer market. Overseas-born residents reach 26.5%, which is 4.9 points above national, while university qualifications at 26.5% run 3.6 points below national, consistent with a workforce weighted toward trades and clerical roles. Ancestry leans Anglo, led by English (1,744), with Filipino (401) the largest non-Anglo group, and the top non-English languages are Arabic (132), Hindi (38) and Punjabi (32). Christianity dominates at 4,067 residents, with Islam (324) and Hinduism (128) following. Couples with children make up the largest family type, far outnumbering the 1,116 couples without children.

Tenure
Tenure tilts firmly toward owner-occupiers: 49.2% carry a mortgage and 31.1% own outright, leaving renters at just 19.7%. That mortgage-heavy mix reflects a younger, family buyer base still paying down recently purchased homes rather than long-held debt-free wealth. The stock is 98.3% separate houses with apartments at only 0.5%, and 59.6% of dwellings have four or more bedrooms, so this is large detached-family housing almost end to end. The median house price climbed from $1,097,500 to $1,183,000 across 2024 to 2025, a 7.8% one-year gain. Both stress measures stay comfortable, with mortgage-to-income at 21.3% and rent-to-income at 19.2%, each well below the 30% threshold, a direct result of household incomes in the 89.2nd percentile meeting sub-Sydney-median prices.

Economy & Employment
The local workforce concentrates in Healthcare at 16.7% (334 workers), Construction at 13.3% (266) and Education at 9.4% (187), with Manufacturing (9.2%) and Transport (7.5%) rounding out the top five, a notably blue-collar mix for greater Sydney. By occupation, Clerical and Admin roles lead at 630, ahead of Professionals at 505 and Machinery operators and drivers at 419, which explains why the IEO education-and-occupation index sits only in decile 4. The contrast with decile 9 on economic resources (IER) is the key anomaly: incomes and assets are strong, but qualification levels are not, a pattern typical of trade-driven outer suburbs. Unemployment is 5.0% and the full-time employment rate is 67.8%, while real incomes grew 8.6% over the decade.

Transport to Work
This is a car-dependent suburb: 91.6% of residents drive to work while only 1.7% use public transport and 0.8% walk or cycle, far below city averages and a function of the low-density, 772.7 residents per square kilometre layout. On the SEIFA disadvantage measures the suburb sits in decile 6 on both IRSD and IRSAD, mid-tier nationally, while economic resources reach decile 9, so material comfort outpaces broader advantage. Only 4.6% of residents (285 people) need daily assistance, low for a suburb whose senior share is rising. No schools are recorded inside the 8.39 square kilometre boundary in this dataset, so families rely on schools in neighbouring suburbs, a common trade-off in detached outer-Sydney areas where lots are large and amenities spread thin.

Population Forecast

(-34 people/yr)
EstablishedThis is an established, slowly shrinking suburb. Annual population growth is negative at 0.53%, the 10-year change is down 2.7%, and the population has drifted from 6,452 in 2023 to 6,450 in 2025. Medium forecasts continue that trend, projecting the population to fall from 6,382 in 2026 to 6,209 by 2031. The driver mix is net negative: overseas migration adds 31 residents a year but internal migration removes 101, so people are leaving faster than they arrive. The trajectory is aging, with the senior share up 6.5 points and the young share down 3.9 points over the decade. The gentrification stage reads not gentrifying, fitting a built-out detached-housing suburb with little room for new dwelling supply and affordability that has stayed stable near 49.7%.

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.
