Homebuyers are paying for new large-format housing rather than scarcity alone: the median house price is $1,350,000, while the 2025 price series peaks at $1,477,500 after an 18.4% lift from 2024. The suburb suits larger households because 78.1% of dwellings have 4 or more bedrooms and 82.6% are separate houses, much higher than apartment living at 14.4%. Mortgage payments absorb 24.1% of income, below stress settings, but 58.3% of homes carry a mortgage, so rate sensitivity is real.
For Buyers

Mortgage payments absorb 24.1% of income, below stress settings, but 58.3% of homes carry a mortgage, so rate sensitivity is real.
For Investors
Investors see a tenant pool tied to young families and recent movers rather than a pure apartment market. Renting sits at 28.0%, with weekly rent at $600 and vacancy at 4.4%, which is higher than a tight market and may limit short term pricing power. The upside is demand depth: 153 development applications in 12 months show continuing build-out, while forecast migration averages 804 net internal arrivals and 205 net overseas arrivals a year. That supports leasing because new households keep forming.

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.
