Rosslyn Park
At $2,305,000, the median house price in Rosslyn Park sits well above the South Australian state average, yet household income lands only at the 84.3rd percentile nationally, meaning buyers here stretch further than their incomes alone would predict. The suburb's most striking feature is its ownership structure: 56.8% of residents own their homes outright, more than double the national rate, pointing to a long-settled, debt-free population rather than a revolving market. The median age of 49 is 9 years above the national figure, and 59.2% hold university qualifications, which is 29.1 percentage points above national. On 0.82 km2, Rosslyn Park is compact, with 1,781 residents per km2.

Median 1Q 2026
The median house price reached $2,305,000 in 1Q 2026, up 14.5% from $2,012,500 in 1Q 2025, one of the faster one-year moves in the Adelaide Hills fringe. Monthly mortgage repayments average $2,600, producing a mortgage-to-income ratio of 27.0%, just below the 30% stress threshold compared to many premium markets. Separate houses make up 82.9% of dwellings, with 47.0% having four or more bedrooms, so buyers get substantial family-size homes rather than high-density product. Semi-detached properties account for 10.4% and apartments just 6.7%. The high outright ownership rate of 56.8% means few properties trade at any given time, which keeps competition for listings acute and supports the rapid price appreciation seen over the past year.

For Investors
Rosslyn Park is a low-yield, capital-growth market. Weekly rent of $398 against a $2,305,000 median implies a gross yield well below 1%, lower than most Adelaide suburbs. The vacancy rate of 6.5% is elevated compared to the broader Adelaide average, which tends to run under 2%, signalling limited rental demand relative to the stock available. Only 13.9% of residents rent, one of the lowest renter shares across the metropolitan area. Annual net internal migration averages 44 residents and net overseas migration 15, providing modest but steady demand. Rent has grown 83% over the decade, faster than income growth of 6.9% in real terms. With 18 development applications in the past 12 months, activity is limited, keeping supply constrained.

Tenure
Tenure is dominated by outright owners at 56.8%, with mortgage holders at 29.3% and renters at 13.9%. Outright ownership at this level reflects a resident base that has held property for decades rather than recent entrants. Separate houses account for 82.9% of dwellings, with four-plus bedroom homes the most common configuration at 47.0%, followed by three-bedroom at 38.0%. The median house price climbed from $2,012,500 in 1Q 2025 to $2,305,000 in 1Q 2026, a 14.5% rise in one year. Mortgage-to-income sits at 27.0% and rent-to-income at 17.9%, both below the standard 30% stress threshold, so current residents are not financially stretched compared to buyers in higher-leveraged outer suburbs. The compact 0.82 km2 boundary limits new supply.

Economy & Employment
Healthcare is the dominant employer at 27.3% of the local workforce (144 workers), well above the share seen in most suburban areas, likely reflecting the age profile and proximity to major hospitals. Professional and Technical services follow at 13.7% (72 workers) and Education at 12.3% (65 workers). By occupation, Professionals make up the largest group (273), ahead of Managers (128) and Clerical/Admin (98). Unemployment is 3.3%, slightly below the national average, and the full-time employment rate is 58.6%. Personal weekly income of $986 and family weekly income of $2,788 reflect a workforce concentrated in knowledge and health sectors. SEIFA IRSAD decile is 5, at the national median, which sits lower than the income percentile of 84.3 because the high outright ownership rate reduces measured financial disadvantage.

Transport to Work
Car use is high at 86.2% of commuters, compared to the national average, with public transport at just 6.0% and walking or cycling at 4.1%, reflecting the suburb's low-density, residential character rather than transit-oriented infrastructure.

The IRSAD decile of 5 places Rosslyn Park at the national median for relative advantage, while the IRSD decile of 4 suggests slightly elevated relative disadvantage on that measure alone. Volunteering runs at 20.1%, above typical metropolitan rates. Only 4.7% of residents need daily assistance. Housing stress is contained: rent-to-income at 17.9% and mortgage-to-income at 27.0% both sit below the 30% threshold that defines financial stress compared to national benchmarks.

Affordability has worsened, with the mortgage-to-income ratio rising from 21.2% in 2011 to 29.5% in 2021, a trajectory that may moderate entry-level demand even as established owners benefit from capital appreciation.

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.
