Woodside Native Reforestation Project - Phase 4

Woodside Native Reforestation Project - Phase 4 is an environmental planting project located across areas near Coorow and Dalwallinu, approximately 250km north of Perth in Western Australia. It was registered in May 2023 and initially covered 4,873.71 hectares. In June and October 2025, variations were made to the project where specific listed areas were removed.

Environmental planting projects involve establishing permanent plantings of a mix of native tree species on land that was predominantly used for agricultural purposes for at least five years prior to project commencement. The methodology requires planting native trees at densities sufficient to achieve a forest cover, which often involves hand-planting seedlings at 3-metre intervals within prepared furrows. The proponent has nominated a permanence period of 100 years for this project to ensure long-term carbon sequestration.

The Dalwallinu and Coorow regions are well known for broadacre agriculture, primarily wheat and canola cropping alongside sheep grazing. The local climate is Mediterranean to semi-arid, experiencing winter-dominant, moderate annual rainfall of approximately 350mm to 450mm. The environmental conditions present highly varied soils, commonly featuring lateritic sandy gravels, pale spillway sands, and alkaline red shallow loamy duplex soils.

This project forms part of Woodside Energy’s broader carbon offset strategy, returning low-productivity agricultural land to native vegetation to increase regional biodiversity and stabilize soil. During the first half of 2025, Woodside progressed its native reforestation activities, forecasting the planting of approximately 2 million biodiverse seedlings across its Western Australian properties. Interestingly, for some of the properties acquired for this project, title boundaries are being realigned so that the higher-productivity land can be sold back to local farmers. This approach ensures the ongoing agricultural viability of the area while dedicating only the less productive zones to permanent carbon farming.
