That latest level is higher than the earlier median because prices rose across the observed year. Housing is not limited to detached stock: 66.9% of homes are separate houses, 18.0% semi-detached and 15.0% apartments. Three-bedroom homes account for 48.0%, while 4-plus-bedroom homes make up 28.8%. Mortgage costs are not flagged as stressed, at 19.7% of household income, but buyers should still allow for the $1,659 monthly repayment estimate.

For Buyers

That latest level is higher than the earlier median because prices rose across the observed year. Housing is not limited to detached stock: 66.9% of homes are separate houses, 18.0% semi-detached and 15.0% apartments.

Mortgage costs are not flagged as stressed, at 19.7% of household income, but buyers should still allow for the $1,659 monthly repayment estimate.

For Investors

Investor conditions are supported by a sizeable rental base and active turnover. Renting accounts for 38.9% of occupied dwellings, compared with 17.5% owned outright, and the typical weekly rent is $360. Vacancy is 6.1%, giving tenants more choice than in a tightly constrained market, although the figure still warrants checking by property type. Development activity reached 59 applications in 12 months, which can add amenity and competing supply.

Transport to Work

Daily life is car-oriented: 75.1% travel as car drivers, compared with 6.2% using public transport, while 11.3% work from home and 2.4% walk or cycle. Local schooling includes 1 government primary school, Mawson Lakes School; families should check enrolment zones against the exact address because boundaries can affect access. Recorded crime totals 894 incidents, or 64.8 per 1,000 residents, so recent street-level patterns are worth reviewing before choosing a home. An IRSAD decile of 7 and an IRSD decile of 7 place local social conditions above the national midpoint, while the 2,238.4 people-per-sq-km density can support nearby daily services but may mean less private space than lower-density areas.

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.
