Mortgage costs sit at $1,700 a month and 21.0% of income, below a stress reading, which helps explain the high 46.0% mortgage share.

For Investors

Investors face a smaller rental pool than in higher turnover suburbs because only 14.4% of households rent and 39.7% own outright. Weekly rent is $380, while the vacancy rate is 4.0%, so income may be steadier for well-located houses but leasing conditions are less tight than shortage markets. Development activity is notable at 115 applications in 12 months, suggesting ongoing renovations and replacement dwellings rather than rapid density, supported by a forecast net overseas gain of 166 people a year.

Ownership is the core housing story: 39.7% own outright and 46.0% are paying a mortgage, compared with just 14.4% renting. The price record is short but positive, moving from $940,000 in 1Q 2025 to $985,000 in 1Q 2026, a 4.8% annual lift and current peak. Density is limited because apartments are only 0.1% and semi-detached homes 5.1%. With rent at 20.3% of income and mortgage at 21.0%, stress readings sit below pressure levels for many households.

School choice is local rather than broad: 3 government schools range from ICSEA 989 to 1056, led by Hallett Cove East Primary at 1056 and Hallett Cove School with 1,243 enrolments. Safety is a strength, with 240 recorded offences and 19.2 per 1,000 residents, while IRSAD ranks decile 7.

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 Valuer-General (house prices), Department of Jobs SALM (unemployment), ACARA (school ICSEA), state Crime Statistics agencies (offences), council DA portals (development applications). Population forecasts use a Hamilton-Perry cohort model calibrated to ABS ERP.
