Windsor Gardens
At 5,827 residents across 2.52 square kilometres, Windsor Gardens is a compact northern Adelaide suburb with a surprisingly international and highly educated profile: 40.7% were born overseas and 47.5% have university qualifications. University attainment sits 17.4 percentage points above the national comparison, while the overseas-born share is 19.1 points higher. The 36 median age is 4 years below national, helping explain the mix of working households and family housing. Compared with nearby Klemzig's more mixed urban setting, Windsor Gardens is defined by detached stock, with 78.5% separate houses and 61.8% three-bedroom homes. Its 5.7% vacancy rate and 22.5% turnover point to an established but changing market.

For Investors
Investor demand has a usable tenant base: 35.3% of households rent, higher than the 27.2% owned outright, and weekly rent is $320. Vacancy is 5.7%, so leasing conditions may be less tight than in lower-vacancy markets and property selection matters. Recent momentum is visible in 63 development applications over 12 months, including an application for 2 detached dwellings, while rent growth is recorded at 27.0%. Overseas migration is the primary growth driver, which can support rental demand because new arrivals often enter the rental market before buying.

Demographics
Windsor Gardens has a median age of 36, 4 years below the national comparison, and an average household size of 2.5, matching the national figure. Its 40.7% overseas-born share is 19.1 percentage points above national, with English ancestry recorded for 1,520 people, followed by Indian at 563, Italian at 547 and Chinese at 509.

Compared with older northern suburbs, the below-national age profile and 77.5% stay rate suggest both family continuity and fresh migration.

Tenure
Tenure is split across 27.2% outright owners, 36.4% mortgagors and 35.3% renters, so no single group dominates. The built form is detached-dominant, with 78.5% separate houses, 19.0% semi-detached dwellings and only 0.7% apartments; 61.8% have 3 bedrooms. Compared with more apartment-oriented Klemzig, that mix supports a family-house profile, while the 23.1% mortgage-to-income measure and 20.0% rent-to-income figure indicate housing costs are material but not flagged as stress. The 5.7% vacancy rate adds choice for renters.

Economy & Employment
Healthcare anchors employment at 22.4% and 500 workers, followed by Education at 11.5% and 256, Professional/Tech at 10.4% and 232, Public Administration at 7.7% and 172, and Retail at 6.5% and 144. That service mix helps explain why Professionals number 791, ahead of Community/Personal at 415 and Clerical/Admin at 392. Participation is 66.3%, full-time employment 56.9%, and unemployment 5.5%, while weekly household income sits at $1,602, around the 52.6 percentile. The socioeconomic pattern is uneven: education and occupation stand at decile 7, but economic resources are decile 3, while disadvantage and advantage both sit at decile 5. Compared with a higher-income professional enclave, Windsor Gardens has a broader service-worker base, which can moderate price resilience even as healthcare demand remains steady.

Transport to Work
Daily travel is car-led: 71.5% drive to work, compared with 10.9% using public transport, 2.0% walking or cycling and 11.2% working from home. The compact 2.52 sq km footprint and density of 2,312.8 people per square kilometre can make local errands manageable, but the transport split means households without cars need to check routes carefully. One government primary/secondary combined school, Avenues College, is listed locally; enrolment zones should be checked against the exact address because boundaries can cut across suburbs. Recorded crime is 288 incidents, or 49.4 per 1,000 residents, while IRSAD sits at decile 5, suggesting a middle position on broad advantage and disadvantage. Compared with a transit-oriented inner suburb, Windsor Gardens is more dependent on private vehicles, so access quality varies by street and destination.

Population Forecast
+1.55%/yr
(+139 people/yr)
EstablishedThe established-area outlook points to steady change rather than a sudden population jump. Annual growth is forecast at 1.55%, with overseas migration named as the primary driver, while population change across the wider area is 24.8% over 10 years. The shift trajectory is labelled Declining young, matching a 2.2 percentage-point fall in the young share, although the working share rises 0.6 points. Gentrification signals are still developing: the forecast score is 26 at the Early signs stage, while the shift profile records a score of 48 and an Active stage. Rent growth of 27.0% and real income growth of 14.8% help explain why demand can strengthen even as the suburb remains established. Compared with a mature suburb with flat rents, Windsor Gardens has more visible transition pressure.

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), SA Department for Housing and Urban Development (house prices), state education open registers (school locations), state Crime Statistics agencies (offences), council DA portals (development applications). Population forecasts use a Hamilton-Perry cohort model calibrated to ABS ERP.
