NSW 2145 Census 2021 + Live DA Data

South Wentworthville

Nearly half of residents here (48.5%) were born overseas, 26.9 points above the national figure, and that migrant weight shapes everything from the 3.0-person average household to a $930,000 median house price that still undercuts most of Sydney. The median age of 35 sits 5 years below national, a younger profile driven by Lebanese (1,327) and Indian (670) families settling into a detached-housing pocket where 56.7% of dwellings are separate houses. SEIFA reads mid-pack: IEO at decile 6 for education but IRSD at decile 3 for relative disadvantage, a split that reflects strong qualifications (40.7% hold a degree) sitting alongside an 8.0% unemployment rate.

At a $930,000 median, South Wentworthville offers buyers a detached-house entry point well below Sydney's prime markets, and the stock supports families: 56.7% are separate houses, 42.3% have three bedrooms and 30.3% have four or more. Prices climbed 13.3% in a single year, from $875,000 in 2024 to $991,000 in 2025, faster than incomes grew, so timing matters. Monthly mortgage repayments average $2,260, producing a mortgage-to-income ratio of 29.1%, just under the 30% stress threshold, which keeps the area accessible to dual-income households earning the $1,793 weekly median. Outright owners (24.5%) trail mortgage holders (35.5%), a sign of a market churning with recent buyers rather than long-settled wealth, consistent with the younger median age of 35.

Outright owners (24.5%) trail mortgage holders (35.5%), a sign of a market churning with recent buyers rather than long-settled wealth, consistent with the younger median age of 35.

For Investors

A 40.0% renter share gives landlords a deep tenant pool, and weekly rent of $450 against the $930,000 median implies a gross yield near 2.5%, modest but ahead of premium inner-Sydney suburbs. Rent climbed 31.4% over the measured period, faster than the national average, so income is rising even where yield starts low. The 8.0% vacancy rate is a caution, signalling softness in the small apartment segment (just 7.0% of stock), though detached and semi-detached homes (93.0% combined) face tighter supply. Demand support is steady: net overseas migration adds 117 residents a year, offsetting an internal outflow of the same size, and development activity ran to 60 applications in 12 months, many dual-occupancy and subdivision works that point to densification rather than oversupply.

Demographics

The median age of 35 runs 5.0 years below national, a younger profile that tracks the family-formation stage of recent migrants. Overseas-born residents reach 48.5%, which is 26.9 points above national, the suburb's defining trait, led by Lebanese (1,327), English (791) and Indian (670) ancestry. The most spoken non-English languages are Arabic (671 speakers), Hindi (107) and Gujarati (82), and religion splits across Christianity (3,372), Islam (933) and Hinduism (802), an unusually plural mix. University qualifications at 40.7% sit 10.6 points above national, higher than the mid-tier income would suggest. Average household size is 3.0, half a person above national, consistent with the 2,670 couples-with-children families that dominate over the 896 couples without kids.

Tenure tilts toward debt and rent rather than outright ownership: 35.5% carry a mortgage, 40.0% rent and only 24.5% own outright, a churn profile that fits a younger median age of 35. The stock is family-oriented, 56.7% separate houses and 36.3% semi-detached, leaving apartments at just 7.0%, so detached supply rather than density defines the market. Three-bedroom dwellings account for 42.3% and four-plus 30.3%, with two-bedroom homes at 25.1%. The median house price rose from $875,000 to $991,000 across 2024-2025, a 13.3% one-year move that outpaced wage growth. Mortgage-to-income at 29.1% stays just below the stress line and rent-to-income at 25.1% is comfortable, a rare case where both purchase and rental costs remain manageable against the $1,793 weekly household income.

Economy & Employment

The workforce leans into services rather than knowledge sectors: Healthcare leads at 17.3% (304 workers), Construction follows at 10.2% (178) and Professional/Tech at 9.9% (174), with Retail at 8.5% and Education at 8.4%. By occupation, Professionals (627) and Clerical/Admin (448) top the list, ahead of Managers (330). The SEIFA picture is mixed and worth reading carefully: IEO sits at decile 6 for education and occupation, but IER drops to decile 4 and IRSD to decile 3, a gap that reflects an 8.0% unemployment rate and a low 42.8% participation rate, the latter dragged down by 2,172 residents not in the labour force. Full-time employment runs at 66.4%, and real incomes grew 10.3% over the decade, slower than higher-advantage suburbs but positive.

Transport to Work

Daily life here is car-dependent: 85.4% drive to work while only 6.0% use public transport and 1.6% walk or cycle, above the national reliance on cars and a function of the suburb's outer-west position. No schools are recorded inside the 1.81 km2 boundary in this dataset, so families rely on institutions in neighbouring suburbs, a practical trade-off at a density of 3,822.9 residents per km2. On disadvantage, the suburb scores decile 3 on IRSD and decile 5 on IRSAD, mid-to-lower tiers nationally, with 6.3% of residents (394 people) needing daily assistance. Volunteering runs at 7.9%, below higher-advantage areas, and the 3.0-person average household reflects the family-heavy, migrant-led character that gives the area its community texture.

Established

South Wentworthville is growing steadily rather than booming: annual population growth registers 1.14%, about 88 people a year, and the 10-year change reached 20.6%, well above flat established suburbs. Medium forecasts lift the population from roughly 7,691 in 2025 to 8,262 by 2031, a continuation of trend driven almost entirely by overseas migration of 117 a year, which exactly offsets a net internal outflow of 117. The gentrification stage reads not gentrifying with a score of 7, because the internal outflow and modest 10.3% real income growth signal turnover without displacement. Affordability improved slightly from 68.6% in 2011 to 66.5% in 2021, an easing trend even as house prices rose 13.3% in the latest year.

What schools are in South Wentworthville?

Is South Wentworthville safe?

Detailed crime statistics are not available for South Wentworthville in this dataset. As an indirect indicator, the suburb scores decile 3 on the IRSD index of relative disadvantage, a mid-lower tier, and 6.3% of its residents, about 394 people, need daily assistance.

Is South Wentworthville good for property investment?

Rent of $450 a week against a $930,000 median gives a gross yield near 2.5%, ahead of premium inner-Sydney suburbs, and rent grew 31.4% over the period. The 40.0% renter share supports demand, but an 8.0% vacancy rate means returns lean on rent growth and capital gains.

How is South Wentworthville's population changing?

Population growth is 1.14% annually, about 88 people a year, with a 20.6% rise over 10 years. Medium forecasts lift the count to 8,262 by 2031. Growth is driven by overseas migration of 117 a year, which offsets a net internal outflow of 117.

About 48.5% of residents were born overseas, 26.9 points above national. English is the dominant language, with Arabic (671 speakers), Hindi (107), Gujarati (82) and Mandarin (66) the most common non-English languages, reflecting a strongly multicultural Lebanese and Indian community.

How much development is happening in South Wentworthville?

There were 60 development applications lodged in the past 12 months, many of them dual-occupancy and subdivision works. This points to gradual densification on detached lots rather than apartment supply, consistent with 1.14% annual population growth and a stock that is only 7.0% apartments.

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.
