Greenwich
Greenwich's most striking feature is its concentration of affluence in just 1.66 sq km: 5,469 residents live at 3,290 people per sq km, while household income sits at the 96.9th percentile. The median age is 42, or 2.0 years above the national comparison, and 69.0% have university qualifications, 38.9 points above national levels. With 43.8% apartments and 50.5% separate houses, Greenwich suits buyers wanting choice in a compact Lower North Shore setting. It sits near Lane Cove and North Sydney, but its strongest identity is established wealth, high professional employment and a gradual aging pattern.

Homebuyers need to match dwelling type to budget because Greenwich is split between 50.5% separate houses and 43.8% apartments, with another 5.7% semi-detached stock. Larger homes are material: 33.6% contain 4 or more bedrooms, compared with 28.3% for 3-bedroom homes and 28.4% for 2-bedroom homes. Mortgage payments are $3,000 per month, while mortgage costs equal 23.5% of household income. Household income of $2,946 weekly sits at the 96.9th percentile, above national levels, but buyers should compare strata costs, renovation scope and resale appeal rather than relying on suburb-wide averages.

For Investors
Greenwich has a sizeable rental audience: 31.3% of dwellings are rented, higher than the 28.2% share with a mortgage. Weekly rent is $550 and vacancy is 8.0%, so leasing performance may depend on presentation, pricing and the dwelling's access rather than scarcity alone. Development activity reached 65 applications in 12 months, spanning home alterations, pools and commercial or use changes, which points to ongoing owner investment but does not establish a pipeline of new dwellings. The annual growth trend is 0.17%, and overseas migration is the primary driver. Compared with a high-growth market, this is a slower capital-growth profile, so investors should weigh yield, vacancy and apartment strata costs together.

Demographics
Greenwich is older and more university educated than the national profile: its median age is 42, 2.0 years above national, while 69.0% have university qualifications, 38.9 percentage points above national. Overseas-born residents account for 35.2%, 13.6 points above the national comparison. English ancestry is recorded for 1,854 people, followed by Irish at 740, Scottish at 640 and Chinese at 573. No religion leads at 2,378, narrowly above Christianity at 2,303, with Hinduism at 181. Average household size is 2.4, or 0.1 below national, and 42.5% of households are couples without children. These patterns help explain a professional, smaller-household setting with an aging trajectory rather than a family-only market.

Tenure
Greenwich has a mixed tenure and dwelling profile. Outright ownership is 37.1%, higher than the 28.2% mortgage share, while 31.3% rent their home. The stock is almost evenly divided between 50.5% separate houses and 43.8% apartments, with 5.7% semi-detached homes, so housing choices are broader than in a detached-only suburb. Bedroom sizes are spread across 2-bedroom homes at 28.4%, 3-bedroom homes at 28.3% and 4 or more bedrooms at 33.6%; only 9.8% are studio or 1-bedroom dwellings. A $3,000 monthly mortgage and $550 weekly rent sit alongside mortgage-to-income of 23.5% and rent-to-income of 18.7%. The mix supports both established owners and apartment renters, but costs and strata obligations can differ sharply by dwelling type.

Transport to Work
Greenwich's livability profile favours home-based work and local routines. Work from home is 63.1%, much higher than public transport use at 3.5% and walking or cycling at 7.8%, so buyers should assess parking, walking routes and service access around the exact address. One local government primary school, Greenwich Public School, is identified; families seeking secondary or non-government options should check enrolment zones and commute times because boundaries can cut across suburb lines. Socioeconomic conditions are strong, with IRSAD at decile 10 and only 2.9% needing assistance, both above lower-ranked settings. Check current NSW Police crime figures and visit at different times before deciding. The average household size of 2.4 also suits smaller households more than a high-density family-only setting.

Population Forecast
+0.17%/yr
(+23 people/yr)
EstablishedGreenwich's growth outlook is established and slow: the annual trend is 0.17%, with Overseas migration named as the primary driver. Population change across the wider area is 7.5% over 10 years, while the trajectory is Aging. That direction fits a senior-share increase of 3.5 points and a young-share decline of 1.8 points, which can limit household turnover and reduce the pace of new family demand. Rent growth of 20.0% is higher than the annual population trend, creating more pressure on housing costs than on resident numbers. The gentrification score is 10 and labelled Not gentrifying, so Greenwich looks more established than transformational. Compared with faster-growth locations, its appeal rests on continuity, income and scarcity rather than rapid expansion.

Is Greenwich safe?
Review current NSW Police figures and inspect the area at different times before making a safety decision. A suburb-specific crime rate is not stated here, so do not infer safety from the 37.1% outright ownership rate or the 63.1% work-from-home rate. Street-level conditions and property location still matter.

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 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.
