That suits larger families because average household size is 3.3, above the national level by 0.8 people. The median house price is not available, so borrowing comfort matters more than price trend reading; the typical mortgage is $2,100 a month and mortgage repayments take 20.5% of income, below common stress thresholds.

For Investors
Investor appeal is more yield-stability than churn. Renting is low at 16.9%, below many middle-ring Perth suburbs, because 63.1% of homes carry a mortgage and families tend to stay for space. Weekly rent is $420 and the vacancy rate is 3.6%, so cash flow depends on tenant quality rather than scarcity alone. With 0 development approvals in the past 12 months and forecast overseas migration averaging 388 people a year, supply pressure is more about population growth than new stock.

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.
