Robinson Sunny Park Coonamble Project

Robinson Sunny Park Coonamble Project is a soil carbon project located approximately 30km southeast of Coonamble in the Central West region of New South Wales. It was registered in March 2020 and covers an initial area of 5,436.99 ha, though a project variation in August 2025 resulted in certain land areas being removed from the boundary.

Soil carbon projects operating under the Measurement and Models Methodology 2021 involve adopting new or materially altered agricultural management practices to sequester carbon in the soil. Standard requirements include undertaking one or more eligible land management activities, combined with verifying the stored carbon over time through direct soil sampling or approved modelling techniques. This project initially operated under the 2018 method but transitioned to the updated 2021 determination in December 2022.

The Coonamble region is heavily utilised for agricultural purposes, particularly sheep and cattle grazing alongside dryland cropping. The area typically experiences a semi-arid climate, receiving an average annual rainfall of approximately 500mm. The local environment is characterised by diverse but challenging soil types, predominantly heavy grey clays and hardsetting red loams.

This project aims to directly increase carbon in the agricultural soil system by altering the stocking rate, duration, and intensity of grazing to promote vegetation cover and improve overall soil health. Furthermore, the proponent is applying gypsum to remediate sodic or magnesic soils, and addressing material soil deficiencies by applying nutrients in the form of synthetic or non-synthetic fertilisers. The project was established by Adam Robinson Pty Ltd as the Trustee for the Adam Robinson Family Trust, with Climate Friendly Pty Ltd acting as the project agent. Interestingly, the project secured an optional delivery contract (CAC838822) with the Commonwealth at the March 2020 auction, originally committing a volume of 180,000 ACCUs.
