Final report - Maximising Tropical Forestry Project (Tiwi Forestry) - Cooperative Research Centre for Developing Northern Australia

Summary

This final report presents the findings of the Maximising Tropical Forestry Project, a collaborative research program designed to improve the productivity, value and long-term sustainability of plantation forestry on the Tiwi Islands.

Led by Tiwi Plantations Corporation, the project brought together Tiwi people, industry and research partners to address key questions associated with establishing a second rotation of Eucalyptus pellita. The research focused on improving plantation productivity, identifying opportunities for higher-value timber products and increasing First Nations participation in northern Australia’s forestry sector.

The project identified practical approaches to improve plantation performance, including retaining harvest residues to maintain soil nutrients and moisture, improving fertiliser management, selecting higher-performing tree genetics and better understanding wood properties and processing opportunities. The research also explored breeding and deployment options to support more productive future plantations.

Importantly, the findings have helped de-risk and inform investment in the second plantation rotation, which will see approximately 30,130 hectares replanted with Eucalyptus pellita. The project provides an evidence base to support a more productive and valuable forestry industry on the Tiwi Islands, while strengthening opportunities for Tiwi employment and participation in the sector.

Maximising northern tropical forestry-linking communities and cutting-edge technology Tiwi Islands

This project supported the expansion of tropical hardwood plantations across the Tiwi Islands and northern Australia, combining advanced forestry science with Indigenous-led enterprise development to strengthen productivity, product value and long-term economic opportunities. Delivered through three integrated research programs, the project identified high-performing Eucalyptus pellita genetics, optimised plantation management practices and assessed opportunities for higher-value timber products. Researchers also worked with Aboriginal communities and industry stakeholders to develop a northern forestry industry growth model, providing a framework for future investment, supply chain development and Indigenous participation in the sector. The project directly informed Tiwi Plantations Corporation’s transition from acacia to eucalyptus plantations, contributing to the business case for an $80 million second-rotation investment and the replanting of 30,000 hectares on the Tiwi Islands. The research is now guiding the establishment of 30 million trees over the next decade, while creating a foundation for long-term employment, carbon opportunities and future value-adding industries. By combining cutting-edge genomics, plantation science and community-led development, the project has strengthened the role of Tiwi-owned forestry operations and established a pathway towards a more productive, sustainable and higher-value tropical forestry industry in northern Australia.
