Modbury, SA
By Lauren McCaleb · Reviewed by Dylan Duncan ·
Modbury is a suburb in Adelaide's north-east, in the City of Tea Tree Gully. It sits at the end of the Adelaide O-Bahn busway and is home to the Tea Tree Plaza shopping centre and Modbury Hospital. The suburb was named by R. S. Kelly on the first of September 1840, after his home town of Modbury in Devonshire, England. Robert Simon Kelly bought land at Upper Dry Creek and called his property Treehill, though it became generally known as Modbury Farm, and the village of Modbury grew up on his land from the late 1850s. At the centre of the suburb is Civic Park, a large open reserve across the road from Tea Tree Plaza that is a popular spot for barbecues and picnics in summer.
Less advantaged than the national average
Modbury is more socio-economically advantaged than about 31% of the 14,462 Australian suburbs we score, based on the ABS SEIFA index (raw score 953, where about 1000 is the national average).

Is Modbury 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 Modbury 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.
