Lockleys suits buyers seeking a predominantly detached-house market, but the entry point is high. Three-bedroom homes represent 50.6% of the stock and four-bedroom-plus homes 30.1%, while apartments account for only 9.6%. That mix supports families wanting larger floorplans because 80.3% of dwellings are separate houses. Mortgage repayments are listed at $2,000 per month, with mortgage costs equal to 24.7% of household income, below the level flagged as mortgage stress. Compared with the 1Q 2025 median, recent price growth has been modest.

For Investors

Lockleys has an owner-heavy tenure pattern, with 21.0% of households renting compared with 41.8% owning outright and 34.1% paying a mortgage. The advertised rent figure is $350 per week and vacancy is 6.0%, which gives tenants more choice than a tightly constrained rental market. Investment demand may be supported by the suburb's 0.86% annual growth trend and overseas migration as the primary growth driver. Development activity is notable, with 85 applications in the past 12 months, including a Torrens Title 1 into 2 land division and a two-storey detached dwelling. These applications matter because they can gradually add or renew housing stock, although they do not all create new dwellings.

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.
