South Windsor
An $880,000 median house price sits alongside a renter share of 45.1% here, a combination driven by the detached stock and an affordable entry point relative to greater Sydney. Separate houses make up 75.9% of dwellings while apartments are just 1.5%, so the market is built around families rather than investors chasing density. The population of 5,948 carries a median age of 34, which is 6.0 years below the national figure, and household income lands in the 45.1st percentile nationally. SEIFA puts the suburb at decile 9 on three of four indexes, an advantaged reading that sits above its mid-pack income, reflecting low disadvantage rather than high wealth.

The $880,000 median makes South Windsor an affordable detached option by Sydney standards, and prices rose 5.9% from $850,000 in 2024 to $900,000 in 2025. The stock suits owner-occupiers because 75.9% are separate houses and only 1.5% are apartments, with three-bedroom homes the dominant format at 55.1% and four-plus bedrooms a further 25.8%. Monthly mortgage repayments average $2,000, producing a mortgage-to-income ratio of 31.5%, just above the 30% stress threshold because incomes sit only in the 45.1st percentile nationally. Mortgage holders (37.1%) outnumber outright owners (17.8%), a sign of recent buyers carrying debt rather than an established debt-free base, which is consistent with the younger median age of 34.

For Investors
A renter share of 45.1% and weekly rent of $360 give landlords a broad tenant pool, but the yield math is the draw rather than the price. Against the $880,000 median, that rent implies a gross yield near 2.1%, modest yet stronger than premium inner-Sydney suburbs. The vacancy rate of 4.8% is higher than a tight market would show, so demand is steady rather than scarce. Net overseas migration adds 182 residents a year against an internal outflow of 20, leaving population growth positive at 1.55% annually. Development activity is light at 33 applications in 12 months, much of it secondary dwellings under complying certificates, which signals incremental backyard supply rather than large projects. Rent grew 27.0% over the period, so the case rests on cash flow and steady occupancy more than rapid capital gains.

Demographics
The median age of 34 is 6.0 years below the national figure, marking a younger family profile, and average household size of 2.5 matches the national average exactly. Overseas-born residents reach 15.2%, which is 6.4 points below national, so the suburb is more Anglo-leaning than most of Sydney. Ancestry is led by English (2,251), Scottish (549) and Irish (546), and the largest non-English languages are Arabic (22 speakers), Punjabi (19) and Hindi (18), a small migrant share. University qualifications sit at 19.3%, which is 10.8 points below national, consistent with a workforce weighted toward trades and clerical roles rather than professional degrees. Couples with children form 1,799 families against 999 couples without children, reinforcing the family-oriented character at a median age well under national.

Tenure
Tenure leans toward debt and rental rather than outright ownership: 37.1% carry a mortgage, 45.1% rent and only 17.8% own outright. Mortgage holders outnumbering outright owners more than two to one points to a younger buyer base still paying down loans, which fits the median age of 34. The stock is overwhelmingly detached at 75.9%, with semi-detached at 22.0% and apartments a negligible 1.5%, so buyers compete for houses rather than units. Three-bedroom dwellings dominate at 55.1% and four-plus bedrooms add 25.8%, a family-sized profile. The median rose from $850,000 to $900,000 across 2024 and 2025, a 5.9% one-year move. Mortgage-to-income at 31.5% exceeds the stress threshold while rent-to-income at 24.6% stays comfortable, a gap that shows buying stretches budgets more than renting in this market.

Economy & Employment
The workforce is concentrated in essential and hands-on sectors: Healthcare leads at 15.9% (254 workers), Construction follows at 14.9% (238) and Education at 9.9% (158), with Public Admin at 8.3% and Manufacturing at 7.9%. By occupation, Professionals (353) and Clerical/Admin (351) edge out Labourers (326) and Machinery/Drivers (291), a broad mix rather than a knowledge concentration. Unemployment is 5.1% and the full-time employment rate is 65.0%, while participation reads 51.0%, held down by 1,634 residents not in the labour force. SEIFA shows decile 9 on IRSAD, IRSD and IEO but only decile 5 on IER for economic resources, a gap that reflects the high mortgage and rental load depressing household wealth measures despite low disadvantage. Real incomes grew 14.8% over the decade.

Transport to Work
Car dependence is heavy: 88.0% of residents drive to work while only 2.5% take public transport and 3.8% walk or cycle, well above the national reliance on cars and a function of the outer-ring location. The suburb earns decile 9 on IRSAD, a high advantage tier, and decile 9 on IRSD for relative disadvantage, meaning few residents face deprivation despite mid-pack incomes. Volunteering runs at 10.2% and 7.5% of residents, some 411 people, need daily assistance. No schools are recorded inside the 8.91 km2 boundary in this dataset, so families rely on schools in neighbouring Windsor and the wider Hawkesbury area. Rent-to-income at 24.6% keeps tenants comfortable, while the low density of 667.9 people per km2 reflects the detached, suburban setting.

EstablishedSouth Windsor is expanding steadily: annual population growth registers 1.55%, adding about 139 people a year, and the population climbed 24.8% over the past decade. The current count of 8,951 is up from 8,728 in 2023, and medium forecasts lift it to 9,711 by 2031, a clear upward path rather than the flat trajectory of established Sydney suburbs. Overseas migration of 182 a year is the primary driver, offset by a small internal outflow of 20. The gentrification reading is early signs at a score of 26, supported by population up 32% since 2011 and an accelerating renter shift from 12% to 18%. Affordability improved from 39.1% in 2011 to 35.1% in 2021, so the suburb is growing while staying relatively accessible compared with inner Sydney.

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.
