Challoner Park 23 Carbon Project

Challoner Park 23 Carbon Project is a soil organic carbon sequestration project located approximately 80km south-west of Bollon in the Balonne Shire region of south-west Queensland. It was registered in April 2024 and covers 11,306.31ha.

The Carbon Credits (Estimation of Soil Organic Carbon Sequestration using Measurement and Models) methodology involves landholders undertaking new eligible management activities to build and store carbon in agricultural soils. Standard requirements include preparing a land management strategy, undertaking rigorous baseline soil sampling, and conducting subsequent measurements or modeling to verify carbon increases over time.

The Balonne Shire region is predominantly known for sheep and cattle grazing on native vegetation, alongside some dryland and irrigated cropping. The area experiences a semi-arid climate with highly variable, summer-dominant rainfall averaging around 450-500mm annually. Soils in this landscape generally consist of deep red earths and cracking clays along floodplains.

Managed by project proponent LOAM Carbon Pty Ltd, this specific project aims to increase carbon in the soil by applying nutrients to the land in the form of synthetic or non-synthetic fertilisers to address a material deficiency. Additionally, the project has undergone some boundary adjustments; variations in September 2024 and October 2025 resulted in certain listed areas being removed from the overall project area.
