SA 5159 Census 2021 + Live DA Data

Happy Valley

Happy Valley is defined less by rapid expansion than by settled ownership: 37.1% of homes are owned outright and 51.3% are mortgaged, while renting sits at only 11.6%. Its 90.0% separate-house stock and median age of 42, which is 2.0 years above the national figure, make it more family and retiree oriented than many southern suburbs. Compared with nearby Aberfoyle Park and Woodcroft, the standout numbers are the 17.8 offences per 1,000 residents and household income in the 51.3rd percentile.

For homebuyers, the main trade-off is price versus space. The median house price is $909,750 in 1Q 2026, up 14.0% from $797,750 in 1Q 2025, so entry is higher than a year earlier. Detached homes dominate at 90.0%, with 59.6% of dwellings having 3 bedrooms and 29.5% having 4 or more. Repayments are relatively contained because the typical mortgage is $1,517 per month and mortgage costs equal 22.3% of household income, below stress settings.

For Buyers

For homebuyers, the main trade-off is price versus space. The median house price is $909,750 in 1Q 2026, up 14.0% from $797,750 in 1Q 2025, so entry is higher than a year earlier. Detached homes dominate at 90.0%, with 59.6% of dwellings having 3 bedrooms and 29.5% having 4 or more. Repayments are relatively contained because the typical mortgage is $1,517 per month and mortgage costs equal 22.3% of household income, below stress settings.

For Investors

Investors face a mixed picture: scarcity of rentals is real, but churn is limited. Only 11.6% of households rent, lower than the 37.1% owned-outright share and 51.3% mortgaged share, while the weekly rent is $360 and rent-to-income is 22.9%. Vacancy is 5.0%, so leasing conditions look less constrained. The 115 development applications over 12 months matter because land divisions and detached dwellings can add competing supply even after a 22.4% rent growth phase.

Demographics

The median age is 42, 2.0 years above the national figure, while 19.1% of residents were born overseas, 2.5 percentage points below national. University attainment is 26.9%, also 3.2 points below national, so the suburb leans more toward established households than a student or new-arrival area.

The housing structure is unusually settled. Outright owners make up 37.1% of households and mortgage holders 51.3%, far higher than the 11.6% renting share, so turnover pressure is likely lower.

Yes. There were 115 development applications over the past 12 months, including land division and detached dwelling activity. That is notable for an established suburb and may gradually refresh supply without changing the 90.0% separate-house base quickly.

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.
