Greenwich, NSW
By Lauren McCaleb · Reviewed by Dylan Duncan ·
Greenwich is a leafy harbourside suburb on the Lower North Shore of Sydney, set on a peninsula where the Lane Cove River meets the harbour, about seven kilometres north-west of the city centre in the Municipality of Lane Cove. It was home to the Cammeraygal people of the Eora nation, who lived along these foreshores. The suburb takes its name from Greenwich on the Thames in London, echoed by nearby Putney, Woolwich and Henley; the name first appears when George Green subdivided his land here in 1840. His Georgian sandstone residence, Greenwich House, built in 1836, still stands. The eastern tip, Manns Point, recalls Gother Kerr Mann, an early owner. Today the suburb offers harbour views, pockets of bushland and a netted harbour swimming pool.
Among Australia's more advantaged suburbs
Greenwich is more socio-economically advantaged than about 99% of the 14,462 Australian suburbs we score, based on the ABS SEIFA index (raw score 1175, where about 1000 is the national average).
A socio-economic measure from ABS Census data — not a measure of how good a suburb is to live in or visit. How we calculate this.
Is Greenwich a good place to live?
There’s no single answer — it depends on what matters to you. So instead of one mystery number, we break it down: a transparent score on each part of life we can back with public data, and an honest “not yet” on the parts we can’t.
Strong on the data we score
A weighted blend of the 2 components we can score for Greenwich from public data. It sits alongside — and reconciles with — the socio-economic Suburb Score above; it is a transparent read, not a complete verdict.

Not yet scored
We’d rather leave these open than publish a number we can’t stand behind. Here’s where each one stands.
- Amenities & accessNot scored yet — our OpenStreetMap amenity mapping is still rolling out across suburbs.
- Green spaceNot scored yet — our OpenStreetMap green-space mapping is still rolling out across suburbs.
- TransportNot scored yet — our OpenStreetMap public-transport mapping is still rolling out across suburbs.
- SchoolsNot scored yet — school performance (ACARA / ICSEA) needs a data-reuse licence cleared before we can publish it.
- SafetyNot scored yet — Australia has no single open crime dataset and safety data carries defamation and legal care, so it is gated pending a go/no-go and will be data-only when added.
- CommunityNot scored yet — we won't reduce community to a number from a proxy. We'd rather leave it open than publish an invented value judgement.
A transparent read on public data, not a verdict — and not a measure of any person or community. See our methodology for how each component is worked out and why some aren’t scored yet.
