Challoner Park 23 Carbon Project

Challoner Park 23 Carbon Project is a soil carbon sequestration project located on the "Challoner Park" station, approximately 110km west of Hebel and 214km southwest of St George near the Queensland-New South Wales border. It was registered in April 2024 by proponent LOAM CARBON PTY LTD and covers 11,306.31 hectares. The project initially covered a larger footprint, but variations made in September 2024 and October 2025 removed some areas from the registered project boundaries.

The project operates under the Estimation of Soil Organic Carbon Sequestration using Measurement and Models (2021) methodology. Soil carbon projects involve changing agricultural management practices to store organic carbon in the soil over time. Specifically, this project increases soil carbon by applying nutrients to the land in the form of a synthetic or non-synthetic fertiliser to address a material deficiency. Generating Australian Carbon Credit Units (ACCUs) through this method requires establishing baseline soil carbon levels and conducting ongoing measurements and modeling over a nominated 25-year permanence period.

The Hebel region features a semi-arid climate, typically receiving around 400mm of annual rainfall. The local landscape consists of productive flat to gently sloping plains, dominated by soft red and grey soils and naturally timbered by poplar box. Regional land use is heavily focused on mixed grazing and farming.

Historically, the broader Challoner Park aggregation spans over 20,800 hectares and has been used to run cattle, sheep, and goats alongside extensive wheat cultivation. An interesting feature of the property is its comprehensive exclusion fencing, which renders the land "kangaroo free" and has been highly beneficial for agricultural productivity and pasture management.
