Prestige Carbon Project

Prestige Carbon Project is a soil carbon project located in the Limestone Coast region of South Australia, approximately 20km south of Lucindale and 75km north of Mount Gambier. It was registered in May 2018 and covers an area of 63.71ha.

Soil carbon projects under the Estimation of Soil Organic Carbon Sequestration using Measurement and Models methodology involve actively storing carbon in agricultural soils. This is achieved by introducing new or modified land management practices. The Prestige Carbon Project specifically relies on altering the stocking rate, duration, or intensity of grazing to promote vegetation cover and improve soil health, as well as applying nutrients in the form of a synthetic or non-synthetic fertiliser to address material soil deficiencies. The total carbon stock changes are then estimated using direct soil sampling combined with models.

The Limestone Coast region is well-known for its productive agricultural operations, primarily including sheep and cattle grazing, cropping, forestry, and viticulture. The area around Lucindale experiences a Mediterranean climate with an average annual rainfall of approximately 600mm. Regional soils are diverse, typically consisting of sandy loams and red loam ridges over free-draining limestone, alongside heavier clay-based flats which lend themselves well to these varying agricultural pursuits.

This project increases carbon in the soil of its agricultural system by actively managing grazing and addressing nutrient deficiencies. Notably, the project transitioned to the 2021 Measurement and Models methodology in October 2025, having originally been registered under the older 2014 Grazing Systems method. The project has also undergone variations to its project area in September 2024, and changed its primary participant name from Corporate Carbon Solutions Pty Ltd to Agriprove Solutions Pty Ltd in late 2025. According to the Clean Energy Regulator's ACCU project register, the project has successfully been issued 2,463 Australian Carbon Credit Units (ACCUs) to date. The project is also notably one of a select few registered agricultural soil carbon projects in South Australia, highlighted in regional government assessments of carbon opportunities within the state.
