Wyena Soil Carbon Project

Wyena Soil Carbon Project is a soil carbon sequestration project located at Wyena Station, approximately 110km southwest of Moranbah in Central Queensland. Registered in May 2025, the project covers 12,767 hectares of pastoral land in the Isaac Region. The property operates as a cattle grazing enterprise, specifically known for the Wyena Station & Valley Droughtmaster Stud, situated along the Kilcummin-Diamond Downs Road.

The project operates under the 2021 Soil Carbon methodology, which credits landholders for increasing soil organic carbon (SOC) levels. To achieve this, the project involves altering the stocking rate, duration, and intensity of grazing to promote perennial vegetation cover and improve soil aeration. These management changes are designed to boost the land's photosynthetic capacity, thereby sequestering more carbon into the soil profile, which is verified through a rigorous regime of baseline measurement and subsequent re-sampling or modeling.

The Kilcummin and Moranbah region is characterized by a semi-arid, sub-tropical climate with an average annual rainfall of approximately 600mm, which falls predominantly during the summer months. The local landscape consists largely of "downs" country, featuring fertile cracking clay soils (Vertosols) and basalt-derived earth, which support the native Mitchell and Flinders grasses essential for the region's extensive beef cattle industry.

A notable aspect of this project is its proponent, Australian Natural Capital Pty Ltd. The company has previously secured federal grant funding in partnership with Curtin University to develop advanced soil carbon measurement technologies. This suggests the Wyena project may serve as a commercial deployment site for these high-tech auditing methods, utilizing data analytics and improved soil core sampling to reduce the cost and variability of generating carbon credits.
