Williamstown (SA), SA
By Lauren McCaleb · Reviewed by Dylan Duncan ·
Williamstown is a town in the Adelaide Hills of South Australia, about 51km north-east of Adelaide and 16km south-east of Gawler, on Victoria Creek at the southern edge of the Barossa Valley. Originally known as Victoria Creek, it was laid out by Lewis Johnston, who bought land in 1857 and surveyed the township in 1858, naming it after his son. Farming, orchards, vineyards and timber-milling sustained the district, and a short gold rush followed in 1868. A nearby slab-and-stone homestead dating from 1841 is claimed to be among the oldest in the state. Today Williamstown is a quiet country town and a southern gateway to the Barossa, with nearby reservoirs and Hale Conservation Park offering walking and water sports.

Is Williamstown (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.
Around the national middle
A weighted blend of the 2 components we can score for Williamstown (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.
