Murphy Carbon Project

The Murphy Carbon Project is a soil carbon sequestration initiative located in the locality of Myocum, situated in the Byron Shire hinterland of New South Wales. The project lies approximately 6 kilometers south of Mullumbimby and 8 kilometers west of Byron Bay. Registered in May 2022, the project originally covered a small landholding of 26.66 hectares.

This project operates under the 2021 Soil Carbon methodology (Estimation of Soil Organic Carbon Sequestration using Measurement and Models). This framework allows landholders to earn Australian Carbon Credit Units (ACCUs) by sequestering carbon in agricultural soils. The specific activities employed here focus on grazing management, involving alterations to stocking rates, grazing duration, and intensity. These changes are designed to improve soil vegetation cover and overall soil health, which in turn facilitates the buildup of soil organic carbon.

The Northern Rivers region, where the project is situated, is characterized by a humid subtropical climate with significant annual rainfall, typically exceeding 1,500mm. The local geography is defined by the remnants of the Tweed Volcano, providing fertile, well-drained volcanic soils, often Red Ferrosols (Krasnozems) or clay loams, which are highly conducive to pasture growth and carbon sequestration when managed effectively.

A notable administrative change occurred on March 4, 2025, when the project underwent a variation that removed specific areas from the project boundary. This type of variation often occurs when certain parcels of land are deemed unsuitable for sampling or are excised due to property subdivision or sale. The project is managed by Agriprove Solutions, a prominent soil carbon project developer in Australia that assists farmers with the compliance, measurement, and reporting requirements of the ACCU scheme.
