Greenwich
A lower-North-Shore peninsula of just 1.66 km2 carries household income in the 96.9th percentile nationally and a clean sweep of decile 10 on all four SEIFA indexes, the top advantage tier in the country. The dwelling mix is the surprise: 50.5% separate houses sit almost level with 43.8% apartments, an unusually even split for a premium pocket where the median house price reached $1,440,000 in 2025. University qualifications hit 69.0%, which is 38.9 points above the national figure, and the median age of 42 runs 2.0 years above national, signalling an established, older and highly credentialed resident base rather than a young growth front.

Buyers face a 2025 median house price of $1,440,000, up 23.9% from $1,162,500 in 2024, a sharp one-year move driven by scarce detached stock on a small peninsula. Separate houses make up 50.5% of dwellings against 43.8% apartments, so a true house purchase competes hard for supply. Larger homes are well represented, with 33.6% carrying four or more bedrooms and another 28.3% holding three, which suits family buyers more than the typical inner-Sydney apartment market. Monthly mortgage repayments average $3,000, producing a mortgage-to-income ratio of 23.5%, comfortably below the 30% stress threshold because household incomes sit in the 96.9th percentile. Outright owners at 38.4% outnumber mortgage holders at 29.2%, a sign that much of the housing is held debt-free by long-settled owners.

For Investors
Renters make up 32.4% of households and weekly rent averages $550, giving landlords a steady tenant pool, though yields are thin: that rent against the $1,440,000 house median implies a gross yield near 2.0%, low even by Sydney standards. The 8.0% vacancy rate is elevated and reflects the apartment-heavy half of the stock at 43.8%. Demand support leans on migration, with net overseas inflow of about 200 residents a year offsetting a net internal outflow of 191, leaving population growth at just 0.17% annually. Development activity is modest at 51 applications over 12 months, mostly alterations and single-dwelling work rather than new supply. With rent growth of 20.0% over the period, the case rests on rent escalation and capital preservation more than yield or volume.

Demographics
The median age of 42 is 2.0 years above the national figure, and the trajectory is aging: the senior share rose 3.5 points while the young share fell 1.8 points over the decade. Overseas-born residents reach 35.2%, which is 13.6 points above national, yet ancestry stays Anglo-led, with English (1,854), Irish (740) and Scottish (640) ahead of Chinese (573). The top non-English languages are Mandarin (95 speakers), Cantonese (54) and Hindi (31), a small but distinctly Asian-Pacific layer. University qualifications at 69.0% run 38.9 points above national, among the highest anywhere. Average household size is 2.4, just 0.1 below national, and couples with children (1,823 families) outnumber couples without children (1,235), consistent with the family-oriented detached housing.

Tenure
Tenure splits across thirds: 38.4% own outright, 29.2% carry a mortgage and 32.4% rent. Outright owners outnumbering mortgage holders points to long-held, debt-free wealth rather than recent-buyer churn. The stock is an even contest between 50.5% separate houses and 43.8% apartments, with semi-detached homes only 5.7%, which keeps detached prices elevated through scarcity. Four-plus bedroom dwellings lead at 33.6%, with three-bedroom at 28.3% and two-bedroom at 28.4%, a family-sized profile unusual for the lower North Shore. The median house price climbed from $1,162,500 in 2024 to $1,440,000 in 2025, a 23.9% rise. Mortgage-to-income at 23.5% and rent-to-income at 18.7% both sit well below stress levels, because incomes in the 96.9th percentile absorb the high prices.

Economy & Employment
The local workforce concentrates in high-paying knowledge sectors: Professional and Technical leads at 22.0% (536 workers), Healthcare follows at 17.6% (429) and Finance at 12.1% (294), with Education at 8.5% and Public Administration at 5.8%. By occupation, Professionals (1,355) and Managers (609) dominate, which aligns with the decile 10 IEO score for education and occupation and the decile 10 IER score for economic resources. Unemployment is low at 3.4% and the full-time employment rate is 69.5%, while participation reads 61.7%, held down by 1,354 residents not in the labour force given the older median age of 42. Real incomes grew 20.0% over the decade, and the clean decile 10 sweep across all four SEIFA indexes confirms broad-based advantage rather than a single high-income anomaly.

Transport to Work
Active and public transport see solid use for a peninsula: 21.0% walk or cycle and 9.4% take public transport, while 64.1% drive, below the national reliance on cars. The suburb earns decile 10 on IRSAD, the top advantage tier nationally, and decile 10 on IRSD for relative disadvantage, meaning very few residents face deprivation. Volunteering runs at 21.8% and only 2.9% (151 people) need daily assistance despite the older median age of 42, both markers of an engaged, low-need community. Rent-to-income at 18.7% keeps tenants comfortable. No schools are recorded inside the 1.66 km2 boundary in this dataset, so families rely on institutions in neighbouring lower-North-Shore suburbs, a practical trade-off for the compact setting at 3,290 residents per km2.

Population Forecast
+0.17%/yr
(+23 people/yr)
EstablishedGreenwich is effectively flat: annual population growth registers 0.17%, about 23 residents a year, and the 10-year change is 7.5%, classifying it as an established, slow-growth suburb. Medium projections lift the SA2 population only marginally through 2031, so little real expansion is expected. The sole positive driver is overseas migration at about 200 residents a year, offset by a net internal outflow of 191, a pattern of established owners staying put while newcomers arrive from abroad. The gentrification reading is early signs with a score of 39, modest because the suburb already sits at decile 10 advantage with little room to climb. Affordability improved from 49.6% in 2011 to 40.3% in 2021, though it remains high relative to most markets.

Is Greenwich good for property investment?
Rent of $550 a week against a $1,440,000 house median gives a gross yield near 2.0%, low for Sydney, and the 8.0% vacancy rate is elevated. Net overseas migration of about 200 a year supports demand, but 0.17% annual population growth means returns lean on capital growth over yield.
How is Greenwich's population changing?

About 35.2% of residents were born overseas, 13.6 points above the national figure. English dominates, with Mandarin (95 speakers), Cantonese (54), Hindi (31) and Persian (26) the most common non-English languages, reflecting a small but international resident mix.
How much development is happening in Greenwich?
There were 51 development applications lodged in the past 12 months, modest for a 1.66 km2 suburb. Most are alterations or single-dwelling works rather than new supply, consistent with an established, slow-growth area at 0.17% annual population growth.
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.
