Moonbria Soil Carbon Project

Moonbria Soil Carbon Project is a soil carbon project located approximately 65km south-west of Barcaldine in central-western Queensland. It was registered in March 2026 and covers an expansive 18,508.27 hectares.

Soil carbon projects operating under the Measurement and Models methodology aim to increase the amount of carbon stored in agricultural soils. These projects require establishing a baseline of existing soil carbon through physical core sampling, and then implementing new eligible management activities to build carbon, which is subsequently verified through further testing and modelling.

The Barcaldine and Blackall region is characterised by a semi-arid climate and is traditionally used for extensive cattle and sheep grazing. The soils in this area are typically a mix of heavy clays, sweet pebbly soils, and sandy loams, often supporting Mitchell grass downs and Gidyea scrub.

This project increases soil carbon by altering the stocking rate, duration, and intensity of grazing to promote vegetation cover and improve soil health. Interestingly, the property Moonbria has been part of a significant regional cluster fencing initiative designed to exclude wild dogs. This exclusion fencing enables better management of grazing pressure, supports pasture regeneration, and allows for the successful reintroduction of sheep. The project's proponent, Graeme McDonald, also manages adjoining properties such as Avondale, which hosts its own active soil carbon project. Carbon Link Operations Pty Ltd is involved as an additional project participant.
