Aldinga Beach, SA
By Lauren McCaleb · Reviewed by Dylan Duncan ·
Aldinga Beach is an outer southern suburb of Adelaide, lying within the City of Onkaparinga along the coast of the Fleurieu Peninsula. Before British colonisation the area was Country of the Kaurna people, who occupied the Adelaide plains and the western side of the peninsula; the Kaurna name recorded for Aldinga was Ngaltingga. The long sandy beach is a popular spot for swimming, surfing, snorkelling and scuba diving through the summer, and it looks out over the Aldinga Reef Aquatic Reserve, created to protect an unusual nearshore reef formation. Inland, the Aldinga Scrub Conservation Park preserves a remnant of the coastal scrub that once lined this shore, while the nearby Washpool wetland fills with the winter rains to provide important habitat for waterbirds such as the hooded plover. The smaller Silver Sands holiday area adjoins the suburb to the south, and a post office opened here in 1960 as the district settled into a relaxed seaside community.

Is Aldinga Beach 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 Aldinga Beach from public data. It sits alongside — and reconciles with — the socio-economic Suburb Score above; it is a transparent read, not a complete verdict.

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.
