Hallett Cove, SA
By Lauren McCaleb · Reviewed by Dylan Duncan ·
Hallett Cove is a coastal suburb of Adelaide in the City of Marion, about 21 km south of the city centre, set around a small rocky beach where the Field River meets the sea. It is best known for the Hallett Cove Conservation Park, whose clifftops carry glacial striations — scratches worn into the rock that are among Australia's clearest evidence of the Permian glaciation, when this land lay within the ancient supercontinent of Gondwana. The park also holds deep archaeological significance and great cultural significance for the Kaurna people. The suburb takes its name from John Hallett, who is said to have come upon the cove in 1837 while searching for missing stock. Today it is a quiet residential area valued for its coastal walks and remarkable geology.

Hallett Cove is more socio-economically advantaged than about 71% of the 14,462 Australian suburbs we score, based on the ABS SEIFA index (raw score 1025, 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 Hallett Cove 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.
Around the national middle
A weighted blend of the 2 components we can score for Hallett Cove 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.
