St Johns Park
Nearly 6 in 10 residents of St Johns Park were born overseas, a share 38.1 points above the national figure, yet the suburb is built almost entirely of detached houses at 93.9% of dwellings. That combination of a migrant-majority population in a low-density, owner-held setting defines the place. The $1,240,000 median house price sits well below inner-Sydney levels, while household income lands in the 51.1st percentile, almost exactly the national midpoint. The population skews older at a median age of 43, which is 3.0 years above national, and the SEIFA picture is split: decile 1 on the disadvantage index against decile 5 for economic resources.

The $1,240,000 median house price climbed 7.6% from $1,203,000 in 2024 to $1,295,000 in 2025, a meaningful one-year move yet still far below the median in inner-ring Sydney. Buyers here get genuine family houses rather than apartments: 93.9% of dwellings are separate houses, 49.3% carry four or more bedrooms and another 46.3% have three, so two-bedroom stock is almost absent at 3.5%. That suits the large 3.3-person average household, which is 0.8 above national. The catch is affordability stress, because monthly mortgage repayments of $2,089 push the mortgage-to-income ratio to 30.8%, just above the 30% stress line, since household income only reaches the 51.1st percentile.

For Investors
Renters make up just 21.4% of households, a thin tenant pool because 51.6% of owners hold their homes outright. Weekly rent of $450 against the $1,240,000 median implies a gross yield near 1.9%, low even by Sydney standards, so the case rests on capital growth rather than cash flow. The 2.9% vacancy rate is tight and signals steady demand, and rent has grown 28.6% over the measured period, which helps. Demand support comes from net overseas migration of 112 a year, exactly offset by net internal outflow of 112, leaving population essentially flat. Development is modest at 28 applications in 12 months, mostly single dwelling houses and secondary dwellings rather than new density, so supply stays constrained.

Demographics
St Johns Park is strongly migrant, with 59.7% of residents born overseas, 38.1 points above national, and ancestry led by Vietnamese (1,420) and Chinese (1,357) ahead of English (392) and Italian (374). The top non-English languages are Cantonese (165), Arabic (154) and Khmer (138), reflecting a Southeast and East Asian core. University qualifications reach 35.5%, which is 5.4 points above the national figure, higher than the modest income would suggest. The median age of 43 runs 3.0 years above national and the trajectory is aging, with the senior share up 8.9 points and the working-age share down 5.3 points over the decade. Christianity (3,021) leads religion, followed by a large Buddhist population of 1,682.

Tenure
Tenure tilts heavily to outright ownership: 51.6% own their homes debt-free, 27.0% carry a mortgage and only 21.4% rent, a profile of long-settled, low-churn households confirmed by a 12.3% turnover rate. The stock is overwhelmingly detached at 93.9%, with apartments at just 1.7% and semi-detached at 4.4%, and it is large, since 49.3% of homes have four or more bedrooms versus 46.3% with three. The median house price rose 7.6% from $1,203,000 to $1,295,000 across 2024-2025. Mortgage-to-income at 30.8% sits just above the stress threshold while rent-to-income at 28.7% stays below it, a gap that reflects how recent buyers carry more pressure than the outright-owning majority.

Economy & Employment
Healthcare dominates local employment at 19.4% (225 workers), well ahead of Professional/Tech at 9.2%, Retail at 9.0%, Education at 8.7% and Construction at 8.6%, a spread weighted toward services and trades rather than finance. By occupation Professionals (425) lead, followed by Clerical/Admin (317) and Machinery operators and Drivers (260). The labour market is soft: unemployment runs at 8.7%, above typical Sydney rates, and participation is only 33.8% because 2,759 residents sit outside the labour force, consistent with the aging profile. The SEIFA reading is mixed, with economic resources at decile 5 but the disadvantage index at decile 1, the lowest tier, which the high outright-ownership rate of 51.6% partly cushions against.

Transport to Work
The suburb is heavily car-dependent: 88.9% of commuters drive, while only 2.1% use public transport and 1.7% walk or cycle, well below the national reliance on active and public modes. No schools are recorded inside the 1.98 km2 boundary in this dataset, so families rely on institutions in neighbouring suburbs, though the resident base is reasonably educated with university qualifications at 35.5%, 5.4 points above national. The SEIFA disadvantage index sits at decile 1, the lowest tier, and 10.7% of residents (649 people) need daily assistance, both partly explained by the older median age of 43. Volunteering is low at 5.9%, and the tight 2.9% vacancy rate points to stable, settled occupancy.

Population Forecast

(-2 people/yr)
EstablishedSt Johns Park is an established, slow-growth suburb. The forecast annual change is effectively flat at -0.02%, around two fewer residents a year, against a 10-year change of just 5.3%. Net overseas migration of 112 a year is the only positive driver and is exactly cancelled by net internal outflow of 112, which is why the gentrification stage reads not gentrifying despite an early-signs score of 22. Rent has grown 28.6% over the period while real income rose only 3.4%, a divergence that squeezes tenants. The aging trajectory reinforces the stall, with the senior share up 8.9 points and the young share down 1.6 points over the decade, so demand leans toward downsizing rather than new family formation.

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.
