About Us

Hallett Resources has recently acquired the Truro Quarry from Topcoat Asphalt. With additional Quarries located at McLaren Vale, Kulpara and Wakefield, Hallett Resources have cemented their position as one of the leading suppliers of quality construction materials in South Australia.

Through a strategically placed Quarry network, Hallett Resources currently supplies materials to some of the most significant infrastructure works in the state including the Darlington Upgrade and Torrens 2 Torrens project. In addition to major projects, Hallett Resources also supply Quarry materials to SA Water, Department of Planning, Transport and Infrastructure, local councils, as well as to landscapers and builders, and the wider community.


The Truro Quarry is a high-grade deposit located 6km East of Truro on the Sturt Highway. The rock is strong, hard and durable and ideal for all asphalt and concrete applications. The acquisition is highly regarded and Hallett Resources are determined to develop the Quarry to cater for its growing product demand and to benefit the local community and provide employment opportunities.
