South Wentworthville suits buyers seeking family-sized housing without a predominantly apartment-based market. Separate houses account for 56.7% of dwellings and semi-detached homes a further 36.3%, while 42.3% of homes have 3 bedrooms and 30.3% have 4 or more. The weekly rent of $450 provides a useful affordability reference, and the average mortgage repayment is $2,260 per month. Mortgage costs equal 29.1% of household income, compared with rent at 25.1%, so budget capacity remains important even though neither measure is flagged as stressed. The 3.0-person average household size helps explain the demand for larger dwellings.

For Investors
South Wentworthville has a substantial rental base, with 39.4% of occupied dwellings rented, a higher share than the 24.2% owned outright. Weekly rent is $450 and the vacancy rate is 8.0%, indicating that investors should test leasing assumptions carefully rather than rely on headline demand. Rental growth of 31.4% has outpaced real income growth of 10.3%, which may support revenue but can also limit tenant affordability. Development activity is notable, with 63 applications recorded over 12 months, including secondary dwellings, demolitions and new structures. The wider growth trend is 1.14% annually and is driven primarily by overseas migration.

Tenure

Three-bedroom dwellings form the largest group at 42.3%, followed by 4 or more bedrooms at 30.3% and 2 bedrooms at 25.1%. Renting accounts for 39.4%, higher than the 24.2% owned outright and 35.0% mortgaged. This tenure mix creates a broader rental pool than an outright-owner market, while the $450 weekly rent and 25.1% rent-to-income ratio remain below the 29.1% mortgage-to-income ratio. Compared with apartment-heavy areas, the dwelling mix provides more family-sized stock.

Economy & Employment
Healthcare is the leading industry, employing 304 people or 17.3% of the local workforce, followed by construction at 178, professional and technical services at 174, retail at 149 and education at 147. Occupations are led by 627 professionals, 448 clerical and administrative workers, 330 managers and 291 trades workers. The labour force totals 2,782, with 1,428 employed full time, 723 part time and an unemployment rate of 6.8%. Household income sits at the 63.8th percentile, above the midpoint, but SEIFA results are mixed: education and occupation rank at decile 6, economic resources at decile 4, disadvantage at decile 3 and advantage at decile 5. That gap reflects reasonable earning capacity alongside pockets of socioeconomic pressure.

Transport to Work
Daily mobility is strongly car-oriented, with 50.0% driving to work, compared with 3.5% using public transport and 0.9% walking or cycling. Work-from-home participation is high at 41.5%, which reduces commuting pressure for many households. At 3,822.9 people per square kilometre across 1.81 square kilometres, local convenience depends heavily on the exact street and access to nearby centres. Families should check nearby education options and enrolment zones against the exact address, since boundaries can cut across suburb lines. An IRSAD decile of 5 sits higher than the IRSD decile of 3, but that middle advantage score should be read alongside the 6.3% needing assistance. Check current police and council information before making safety comparisons.

EstablishedSouth Wentworthville has a stable trajectory, with the wider area recording 20.6% population change over 10 years and an annual growth trend of 1.14%. Overseas migration is the primary growth driver, which fits the suburb's 48.5% overseas-born share. The shift indicator labels the trajectory Stable, while rent growth has reached 31.4% and affordability improved from 68.6% in 2011 to 66.5% in 2021 under the stated measure. Gentrification signals are restrained: the main score is 7 with a stage of Not gentrifying, although a separate shift score of 27 is classified as Early signs. Growth therefore looks incremental rather than rapid or redevelopment-led.

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.
