Truro (postcode 5356, altitude 311m) is a town in South Australia, 80 km northeast of Adelaide.

The survey was conducted by Thomas Burr, assisted by his (eventual) son in law Frederick Sinnett, during a period when both were freed from their usual commitments in order to pursue private contracts.

For this reason dry grain crop farming, mainly of wheat and barley, is more prevalent than viticulture.

During the 1970s the town of Truro gained notoriety due to human remains being found scattered among nondescript Mallee scrub upon the arid Murray Plains near Sandleton.

This became widely known as the Truro murders, one of the notable occurrences of serial killing in Australian history.
