Dunworrie Soil Carbon Project

Dunworrie Soil Carbon Project is a soil carbon sequestration project located on the 'Dunworrie' property, approximately 30km north-east of Goondiwindi in Southern Queensland. Registered in February 2026, the project covers 1,807 hectares of agricultural land in a region renowned for mixed farming, including dryland cropping and grazing. The area typically experiences a semi-arid to subtropical climate with an average annual rainfall of roughly 550mm. The landscape likely features a mix of heavy grey cracking clays (Vertosols) suitable for crops, and texture-contrast soils often associated with Bulloak (Allocasuarina luehmannii) woodlands.

The project operates under the 'Estimation of Soil Organic Carbon Sequestration using Measurement and Models 2021' methodology, with Carbon Link Operations Pty Ltd serving as the service provider. This methodology requires the proponent to measure baseline soil carbon levels and implement specific management changes to increase Soil Organic Carbon (SOC) stocks over time. The primary activity for this project is the introduction of legume species into cropping or pasture systems. Legumes are utilised for their ability to naturally fix atmospheric nitrogen, which enhances soil fertility, promotes higher biomass production, and increases the volume of organic matter returning to the soil profile.

The 'Dunworrie' property has a demonstrated history of integrating agricultural production with environmental conservation. Prior to the registration of this carbon project, the property was involved in conservation initiatives to protect the critically endangered Bulloak Jewel Butterfly (Hypochrysops piceatus). This included hosting field days and tree planting projects in partnership with the Macintyre Ag Alliance and Southern Queensland Landscapes to extend habitat corridors, highlighting a dual focus on biodiversity and carbon sequestration.
