Is Upper Main Arm 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.
Lower on the data we score
A weighted blend of the 2 components we can score for Upper Main Arm 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.
