Dunworrie Soil Carbon Project

Dunworrie Soil Carbon Project is a soil carbon project located at the 'Dunworrie' property, approximately 30km north-east of Goondiwindi in Queensland. It was registered in January 2026 and covers 1,807.32 ha.

Estimation of soil organic carbon sequestration projects involve undertaking new land management activities to build soil carbon in grazing or cropping systems. Standard requirements include establishing a baseline of soil carbon through physical sampling, followed by subsequent testing, often using a hybrid of sampling and predictive modelling, to demonstrate carbon increases above the baseline over a 25 or 100-year permanence period.

The Goondiwindi area is known for sheep and cattle grazing, alongside dryland cereal and cotton cropping. The region has a semi-arid climate with summer-dominated rainfall averaging around 620mm annually, and soils generally consist of productive alluvial cracking clays (vertosols), sodosols, and brigalow soils.

This project increases carbon in the agricultural soil by using legume species in cropping or pasture systems. Legumes help naturally fix nitrogen, which improves soil health, encourages deeper root networks, and promotes long-term organic carbon storage. Interestingly, the host property 'Dunworrie' is highly regarded locally for its conservation efforts, having partnered with landcare groups to plant native bulloak trees and create vital habitat corridors to save the critically endangered Bulloak Jewel Butterfly. Furthermore, the project's participant, Carbon Link Operations, is a pioneer in the soil carbon industry known for using advanced spatial modelling, NIR spectroscopy, and remote sensing to accurately measure and monitor soil carbon levels.
