'Stonehaven Carbon Project 3

Stonehaven Carbon Project 3 is a soil organic carbon sequestration project located approximately 26km southeast of Biloela in Central Queensland. It was registered on July 27, 2026, and covers an unspecified project area. The surrounding region within the Banana Shire is widely known for its agricultural land uses, predominantly beef cattle grazing, broadacre cropping, and improved scrub pastures.

The project operates under the Carbon Credits (Carbon Farming Initiative, Estimation of Soil Organic Carbon Sequestration using Measurement and Models) Methodology Determination 2021. Soil carbon projects involve storing carbon within agricultural soils by introducing new or materially altered land management activities. The standard requirements for this methodology mandate establishing a baseline soil carbon level through rigorous physical soil sampling, followed by ongoing measurement and modelling to verify carbon increases over the life of the project.

The environment in the Biloela region is classified as having a sub-tropical, semi-arid climate with a summer-dominant average annual rainfall of approximately 650-700mm. The project sits within the Callide Valley catchment, where typical soil types include heavy and fertile vertosols (cracking clays), sodosols, and brigalow scrub soils. These robust soil structures offer excellent potential for pasture growth and long-term soil carbon retention.

This project increases carbon in the soil across the agricultural system by altering the stocking rate, duration, or intensity of grazing. These targeted project activities are designed to promote soil vegetation cover, prevent overgrazing, and improve overall soil biology and health. The proponent, Agriprove Solutions Pty Ltd, is a major national developer of soil carbon projects and manages a local cluster that includes Stonehaven Carbon Projects 1, 2, and 3. Agriprove is highly active in agricultural research, frequently collaborating with bodies like Meat & Livestock Australia on producer demonstration sites to prove how practice changes can simultaneously deliver commercial livestock benefits and viable carbon abatement.
