Stonyfell
With a median house price of $1,508,000 and household income in the 96.4th percentile nationally, Stonyfell stands as one of Adelaide's most affluent pockets. The suburb's 1,266 residents skew noticeably older, with a median age of 45 that is 5 years above the national figure, and 49.2% own their homes outright, pointing to long-settled, debt-free wealth rather than speculative entry. University qualifications at 61.6% sit 31.5 percentage points above the national average, and just 7.5% of dwellings are rented, making this firmly an owner-occupier suburb with minimal investor footprint.

The entry price for Stonyfell is $1,508,000 at the 1Q 2026 median, down 4.9% from $1,586,000 a year earlier, giving buyers some negotiating room after a period of correction. The stock is heavily skewed toward large detached homes: 92.9% are separate houses and 56.4% have four or more bedrooms, making it one of Adelaide's better suburbs for families seeking space. Monthly mortgage repayments average $2,605, and mortgage-to-income sits at 21.0%, below the 30% stress threshold, which is notable given the price point and reflects the suburb's very high income base. Outright owners outnumber mortgage holders 49.2% to 43.3%, a tenure split that shows how established and equity-rich the existing resident base is.

For Investors
At just 7.5% renters and a 5.0% vacancy rate, Stonyfell is not a rental market. Weekly rent of $565 against a $1,508,000 median implies a gross yield well below 2%, which is unattractive compared to higher-yielding Adelaide suburbs. Demand indicators are also muted: the turnover rate is 13%, meaning 87% of residents stayed in the previous year, and development activity was low at 17 applications in the past 12 months, mostly tree removal works rather than new dwellings. Price momentum is negative, with the median falling 4.9% year-on-year from the 1Q 2025 peak. The investment case here rests on capital preservation in a premium, low-supply suburb rather than yield or short-term growth.

Transport to Work
Car dependency is high at 84.0% of commuters, with only 3.9% using public transport and 4.6% walking or cycling, which is consistent with the suburb's low-density hillside geography. Crime sits at 14.2 incidents per 1,000 residents, a low rate that aligns with the suburb's low-disadvantage profile. Volunteering at 24.5% is notable, above typical community engagement rates and reflecting the established, high-education resident base. Rent-to-income at 19.8% is below national stress benchmarks, and only 2.6% of residents (32 people) need daily assistance despite the older median age of 45. No schools are recorded inside the suburb boundary, so families rely on nearby institutions in surrounding suburbs within the eastern Adelaide foothills.

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.
