NSW 2074 Census 2021 + Live DA Data

South Turramurra

Household income in the 99th percentile nationally and a median house price of $2,455,000 together define South Turramurra as one of Sydney's most financially exclusive pockets. The suburb's 3,208 residents spread across 3.06 km2, giving a density of 1,048 per km2, far lower than inner-city comparisons. University qualifications reach 63.6%, which is 33.5 percentage points above national. Overseas-born residents make up 32.7%, about 11 points above national, and overseas migration of 232 arrivals per year now drives most population growth. At 98.6%, separate houses account for almost the entire dwelling stock, a figure that places the suburb at the extreme end of detached-house dominance.

The median house price sits at $2,455,000, drawn from 2024-2025 PSI data, and the price trajectory tells a cautionary story: the suburb peaked at $2,735,000 in 2024 before settling to $2,310,500 in 2025, a 15.5% pull-back from peak. That correction brings purchase costs closer to reach without removing the premium. Monthly mortgage repayments average $3,500, giving a mortgage-to-income ratio of 23.4%, below the 30% stress threshold despite prices well above the Sydney median. Four-bedroom-plus homes make up 68.4% of stock, higher than most Sydney suburbs, so family buyers are competing for a large but firmly premium supply. Outright ownership at 41.6% outnumbers mortgage holders at 50.2%, a pattern consistent with long-held wealth rather than recent leveraged buyers entering at peak.

Outright ownership at 41.6% outnumbers mortgage holders at 50.2%, a pattern consistent with long-held wealth rather than recent leveraged buyers entering at peak.

For Investors

The rental market is thin: only 8.2% of dwellings are rented, compared to a national renter share closer to 30%, which limits tenant supply. Weekly rent averages $795, and against the $2,455,000 median that implies a gross yield around 1.7%, low even by upper-North Shore standards. Vacancy sits at 2.9%, moderate rather than tight, so competition for rental stock is not intense enough to drive rapid rent escalation. Development activity runs at 38 applications in the past 12 months, mostly CDC and dwelling applications consistent with renovation and rebuild cycles rather than new supply additions. The main demand driver is overseas migration at a net 232 arrivals per year, which supports gradual occupancy growth, but internal migration runs at minus 59 annually, meaning existing residents are steadily leaving.

Demographics

The median age of 42 sits 2 years above the national average, and the demographic shift is running in the same direction: the senior share rose 1.9 points and the young-adult share fell 1.7 points over the decade.

Volunteering reaches 23.4% of residents, noticeably higher than lower-advantage suburbs.

South Turramurra's tenure and stock profile is almost entirely owner-occupied detached houses. Separate houses account for 98.6% of dwellings, compared to the national mix where apartments and semis are far more prevalent. Outright ownership at 41.6% and mortgage holders at 50.2% together leave renters at just 8.2%, reinforcing the owner-dominated character. The bedroom profile skews large: 68.4% of dwellings have four or more bedrooms and 29.3% have three, meaning one-and-two-bedroom options are essentially absent at 2.4% combined. Mortgage-to-income at 23.4% and rent-to-income at 23.1% both sit below the 30% stress threshold, indicating that current residents can service costs comfortably relative to their incomes, which sit at the 99th percentile nationally.

Economy & Employment

The local workforce concentrates in the economy's best-paid sectors. Professional and Technical services lead at 17.7% (221 workers), followed by Healthcare at 15.0% (187) and Education at 12.6% (157), with Finance at 12.0% (150). By occupation, Professionals (606) and Managers (372) together represent well over half of employed residents. Full-time employment runs at 64.6% and the unemployment rate is 5.1%, slightly above the suburb's low-disadvantage expectation, though this may reflect the high proportion not in the labour force at all (825 residents), consistent with the older age profile. All four SEIFA indexes sit at decile 10, the national top tier, covering education and occupation (IEO), economic resources (IER), relative disadvantage (IRSD) and socio-economic advantage (IRSAD). Real income growth over the decade reached 14.7%.

Transport to Work

South Turramurra sits at decile 10 on IRSAD, the national top advantage tier, and scores decile 10 on every other SEIFA index. Car dependency is pronounced: 88.4% of residents drive to work, higher than the Sydney average, while public transport accounts for only 3.4%, reflecting the suburb's low-density footprint and limited rail access compared to closer-in upper-North Shore areas. Only 2.9% of residents need daily assistance and 91 people (2.9%) require support, low figures for a population with a median age of 42. Mortgage stress is absent at 23.4% mortgage-to-income, and rent stress is similarly absent at 23.1%. Volunteering at 23.4% signals high community participation. No schools are recorded inside the suburb boundary in this dataset, so families depend on institutions in neighbouring Turramurra, Pymble and West Pymble.

Established

South Turramurra grows slowly but steadily. The 10-year population change was 12.3%, and the current annual rate is 0.6%, adding roughly 19 people per year to the suburb's 3,208 residents. Medium forecasts for the broader SA2 region project the population rising from 20,593 in 2025 to 21,535 by 2031. Overseas migration is the primary growth engine at 232 net arrivals per year, offsetting an internal outflow of 59 per year. Rent growth of 10.9% over the measured period outpaced general inflation, supporting asset values from the rental side. The gentrification score is 10 out of 100 with a classification of not gentrifying, which fits a suburb already at decile 10 across all SEIFA measures. The affordability trend is recorded as improving, moving from 72.3% in 2011 to 56.8% in 2021, though absolute prices remain among Sydney's highest.

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.
