To ensure its future viability and sustainability, it is vital that the Australian tree nut industry minimises the risks posed by exotic pests and responds effectively to plant pest threats. The Biosecurity Plan for the Tree Nut Industry is a framework to coordinate biosecurity activities and investment for Australia’s tree nut industry. It provides a mechanism for industry, governments and stakeholders to better prepare for and respond to, incursions of pests that could have significant impacts on the tree nut industry. It aims to assist tree nut producers to evaluate the biosecurity risks within their everyday farming and business activities, formally identify and prioritise exotic plant pests (not currently present in Australia), and focus on future biosecurity challenges.
