NSW 2147 Census 2021 + Live DA Data

Seven Hills

A population of 20,095 gives Seven Hills substantial scale, while its 2,086.9 people per square kilometre reflect a built-up suburban setting rather than a low-density fringe. The median age is 37, which is 3.0 years below the national figure, and 46.3% of residents were born overseas, 24.7 percentage points above the national share. Household income sits at the 70.6th percentile, supporting established owner-occupier demand. Compared with the denser feel associated with central Blacktown, Seven Hills is defined by detached housing, with 84.2% of dwellings separate houses. Its large Indian, Chinese and English ancestry groups, plus Punjabi and Hindi language use, give the suburb a more internationally connected profile than many older western Sydney areas.

Seven Hills suits buyers prioritising detached housing, practical space and an established neighbourhood layout. Separate houses account for 84.2% of dwellings, while 50.2% have 3 bedrooms and 31.6% have 4 or more, so family-sized stock is more common than apartments at 5.6%. The mortgage benchmark is $2,200 per month, with mortgage payments representing 26.9% of household income, below the usual stress threshold. Renting costs $400 per week, and 35.9% of households rent, creating useful options for buyers who are not ready to purchase. Compared with a unit-led market, Seven Hills gives families more choice of yards, bedrooms and extensions, although buyers should compare individual streets because the 9.63 square kilometre suburb contains varied housing pockets.

For Buyers

Compared with a unit-led market, Seven Hills gives families more choice of yards, bedrooms and extensions, although buyers should compare individual streets because the 9.63 square kilometre suburb contains varied housing pockets.

For Investors

The rental case rests on a sizeable tenant base, moderate vacancy and ongoing development activity. Renters represent 35.9% of households, slightly above the 35.2% with a mortgage and higher than the 28.0% who own outright. The weekly rent benchmark is $400 and vacancy is 5.5%, suggesting tenants have more choice than in a tightly constrained market, which can limit short-term rental pressure. Development activity reached 234 applications over 12 months, including secondary dwellings and subdivisions, supporting gradual additions to local supply. The forecast trend is 1.78% annually and overseas migration is the primary growth driver. Compared with a purely owner-occupier suburb, Seven Hills offers broader tenant demand, but investors should allow for competition from new or modified dwellings.

Transport to Work

Seven Hills provides a practical, car-oriented suburban lifestyle with established education access. There are 9 government schools nearby, comprising 6 primary schools, 2 secondary schools and 1 school for specific purposes; families should check enrolment zones against the exact address because boundaries can cross local streets. Travel patterns show 47.5% of residents driving a car, compared with 5.7% using public transport, 1.1% walking or cycling and 42.1% working from home. That mix supports local routines but makes transport access more important for households without a car. No suburb-level crime rate is stated, so Seven Hills cannot be ranked above or below other suburbs on safety from this information alone. Its IRSAD decile of 6 is above the middle of the national decile scale, although the IRSD decile of 5 points to mixed conditions between households.

Established

Seven Hills has an established growth profile, with the forecast trend running at 1.78% annually and overseas migration identified as the primary driver. Population change across the wider area is forecast at 25.2% over 10 years, which is above zero and points to continued demand rather than stagnation. The trajectory is labelled Mixed: rent growth is 17.8%, real income growth is 11.8% and the working-age share has shifted by -0.7 percentage points. Gentrification remains at the Early signs stage with a score of 36, while the separate shift measure records a score of 29 and the same stage. This combination suggests gradual change rather than wholesale replacement of the existing housing base. Compared with a new-release corridor, growth is more likely to come through migration, infill and changing household demand than large greenfield estates.

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.
