For Investors
Investor conditions are shaped by limited rental turnover: 13.0% of households rent, vacancy is 4.3%, and weekly rent is $530. Rent growth of 23.3% is higher than the 0.28% annual population trend, which may support income growth but also limits tenant affordability. Development activity reached 129 applications in 12 months, including a two-dwelling dual occupancy and a one-dwelling residential application. Overseas migration is the primary forecast driver, supporting tenant demand, while 88.1% separate housing means maintenance and land value matter more than high-density yields.

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.
