Myall Creek Road Soil Carbon Project

Myall Creek Road Soil Carbon Project is a soil carbon sequestration project located near the locality of Wards River, approximately 35km south of Gloucester and 20km north of Stroud in the Mid-Coast region of New South Wales. Registered in July 2025, the project covers a project area of approximately 530 hectares.

The Wards River and broader Gloucester valley region is renowned for its high rainfall and rolling hills, predominantly utilized for beef cattle grazing and some dairy operations. The soils in this region are often naturally acidic and can exhibit sodicity in subsoils, which constrains pasture growth. This environmental context aligns directly with the project's specific activities, which involve applying lime to ameliorate soil acidity and gypsum to manage sodic or magnesic soil properties. By correcting these chemical constraints, the project aims to improve root depth and biomass production, thereby increasing the rate of soil organic carbon sequestration.

The project operates under the Carbon Credits (Carbon Farming Initiative, Estimation of Soil Organic Carbon Sequestration using Measurement and Models) Methodology Determination 2021. This methodology requires the proponent to establish a baseline of soil carbon through physical sampling, implement new management activities (such as soil amelioration), and then measure or model the increase in soil carbon stocks over time to generate Australian Carbon Credit Units (ACCUs). The proponent, Carbon Fix Pty Limited, manages a portfolio of similar soil carbon projects across New South Wales, including the nearby Bonnington Soil Carbon Project in the Dungog shire.
