Weekly rent is $380 and vacancy is 4.0%, while only 14.3% of households rent, below the combined 85.2% owner-occupier share. Rent growth of 26.7% may improve income prospects, although the modest rental base can narrow the tenant pool compared with higher-rental suburbs. Development activity reached 122 matters in 12 months, indicating ongoing property work even as the annual growth trend sits at 0.11%. Overseas migration is the primary growth driver, which may broaden future rental demand. The gentrification score is 0, with the area classified as not gentrifying.

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.
