Seaton (SA), SA
By Lauren McCaleb · Reviewed by Dylan Duncan ·
Seaton is a residential suburb in Adelaide's west, close to Findon, Grange and West Lakes, and home to the Royal Adelaide Golf Club. The main roads of Tapleys Hill Road and Grange Road run through the area. Before the Second World War the district was largely rural — a patchwork of market gardens, poultry farms and lucerne paddocks bounded to the west by coastal sand dunes. The rapid wartime and post-war expansion of industry nearby, including the munitions works at Hendon and the General Motors-Holden assembly plant at Woodville, prompted the South Australian Housing Trust to build extensive housing for workers across Seaton and its neighbours, and the suburb took on its present settled character. Its first post office opened in 1965, and today Seaton is served by its own primary and high schools.

Is Seaton (SA) 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 Seaton (SA) 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.
