The median house price is $1,172,500, rising from $1,112,500 in 2024 to $1,222,500 in 2025, a 9.9% move in one year. That pace of growth is notable for a suburb outside the major capital cities, suggesting strengthening demand relative to supply. Monthly mortgage repayments average $2,330, which produces a mortgage-to-income ratio of 19.6%, below the 30% stress threshold despite the elevated price point, because household income reaches $2,742 per week. Separate houses dominate at 97.7%, and 60% of dwellings have four or more bedrooms, so buyers are almost always competing for genuine family homes rather than smaller units. Only 12.5% of dwellings are rented, compared to national averages above 30%, confirming owner-occupier demand drives this market.
For Buyers

Only 12.5% of dwellings are rented, compared to national averages above 30%, confirming owner-occupier demand drives this market.
For Investors
The investment fundamentals are modest but stable. Weekly rent averages $483, and against the $1,172,500 median, that implies a gross yield near 2.1%, below the national average for residential property. The 4.0% vacancy rate sits at the upper edge of a healthy range, suggesting some softness in tenant demand relative to available stock. On the positive side, 30 development applications were lodged in the past 12 months, the majority alterations and additions rather than new supply, so competing rental stock is limited. The 9.9% price appreciation recorded from 2024 to 2025 is the stronger investment argument, though only two data points are available and capital growth projections are speculative without longer price history.

Detached houses make up 97.7% of the housing stock, compared to the national share below 75%, making this one of the most house-dominant suburbs in NSW. The size profile skews large: 60% of dwellings have four or more bedrooms and 34.7% have three bedrooms, with just 5.2% having two or fewer. Ownership is high even by owner-occupier standards: 41.7% own outright and 45.7% carry a mortgage, while only 12.5% rent. That 12.5% renter share is well below the national figure and helps explain the 4.0% vacancy rate, since the pool of available rental properties is structurally small. The median house price climbed from $1,112,500 in 2024 to $1,222,500 in 2025, a 9.9% rise, and the rent-to-income ratio of 17.6% means tenants face low housing stress relative to income.

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.
