Seaford Meadows

With 5,102 residents in 3.56 square kilometres, Seaford Meadows is a compact, young mortgage-belt suburb: the median age is 31, which is 9 years below the national figure, while 88.4% of homes are separate houses. Household income sits at the 57.6th percentile, but the suburb's 1,432.6 people per square kilometre make its family streets relatively concentrated. Compared with Seaford, the profile is more detached and family-oriented because 44.0% of couples have children and 36.9% of dwellings have 4 or more bedrooms. The trade-off is car dependence, with 77.8% driving to work and only 5.5% using public transport.

The suburb suits buyers seeking conventional family housing because 88.4% of dwellings are separate houses, with 55.2% containing 3 bedrooms and 36.9% containing 4 or more. Mortgage commitments average $1,610 per month, while the reported mortgage-to-income measure is 22.4%, below the rent-to-income figure of 21.6% only marginally on the supplied measures. The main constraint is the high 48.8% mortgage tenure share, which is higher than outright ownership at 13.0%, keeping the area firmly tied to borrowing conditions.

For Buyers

The suburb suits buyers seeking conventional family housing because 88.4% of dwellings are separate houses, with 55.2% containing 3 bedrooms and 36.9% containing 4 or more. Mortgage commitments average $1,610 per month, while the reported mortgage-to-income measure is 22.4%, below the rent-to-income figure of 21.6% only marginally on the supplied measures. The main constraint is the high 48.8% mortgage tenure share, which is higher than outright ownership at 13.0%, keeping the area firmly tied to borrowing conditions.

For Investors

Seaford Meadows has a substantial tenant base, with 37.9% of households renting and weekly rent at $360. Vacancy is 3.7%, while reported rent growth is 25.0%, giving landlords a stronger recent rental trend than the wider area's 2.37% annual growth rate. Demand is supported by a family housing mix and balanced migration rather than one dominant source of arrivals. Development activity reached 25 applications in 12 months, mostly reflecting ongoing property changes such as carports and verandahs rather than a clearly identified large project. Investors should weigh the low vacancy against the suburb's 88.4% detached-house concentration, because maintenance and land costs can be higher than for apartment stock.

Housing is overwhelmingly detached and family-sized. Separate houses account for 88.4% of dwellings, compared with 7.5% apartments and 4.1% semi-detached homes; 3-bedroom properties make up 55.2% and 4-bedroom-or-larger homes 36.9%. Mortgage holders represent 48.8% of households, higher than renters at 37.9% and far above outright owners at 13.0%. This mortgage-belt structure reflects family demand for larger homes, but it also means affordability is more exposed to interest-rate movements than in a suburb with a larger outright-owned share.

Economy & Employment

Healthcare is the leading industry, employing 400 people or 22.2%, well above construction at 9.6% and retail at 9.4%; education accounts for 8.9% and public administration 7.9%. The occupation mix is similarly broad, led by professionals at 442, trades at 427, community and personal services at 389, clerical and administrative work at 380, and managers at 287. Labour-force participation is 71.8%, full-time employment 60.3%, and unemployment 5.8%, indicating a working-age economy with some pressure at the margin. SEIFA results are middling: IEO is decile 4, IER decile 5, IRSD decile 4 and IRSAD decile 4. The economic-resources score is higher than the other three decile results, consistent with mixed professional, trade and service employment rather than a uniformly advantaged base.

Transport to Work

Daily travel is strongly car-oriented: 77.8% drive to work, compared with 5.5% using public transport and 1.5% walking or cycling. A further 11.2% work from home, which may reduce some commuting demand but does not change the suburb's transport pattern. Families should check school enrolment zones and nearby campuses against the exact address, including sector options, because catchments can differ across surrounding suburbs. Recorded crime totals 299 incidents, equivalent to 58.6 per 1,000 residents. The IRSAD result is decile 4, below the area's IER decile 5, so relative advantage is moderate rather than high. With density at 1,432.6 people per square kilometre, local street conditions and access to services matter more than distance alone.

Population Forecast

+2.37%/yr

(+366 people/yr)

Established

The wider area's forecast trend is 2.37% annual growth, with migration classified as Balanced and the overall trajectory marked Mixed. Population change across the wider area is 44.8% over ten years, pointing to sustained expansion rather than a short-lived post-pandemic spike. The current gentrification score is 27 and staged as Early signs, higher than the separate shift score of 19, which is marked Not gentrifying. Rent growth of 25.0% adds pressure to the housing market, while the young resident share has moved by 0.2 percentage points and the senior share by 2.0 points. Growth is therefore likely to be gradual and varied because balanced migration, family demand and rising rents are operating together.

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), SA Department for Housing and Urban Development (house prices), 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.
