This project was undertaken to investigate the potential for a grower registration scheme to help address biosecurity issues in the vegetable industry. A national grower registration scheme would enable the collection of accurate and up-to-date information about the number and location of growers of different plant species. This report sets out the biosecurity obligations of the industry and the potential role for a grower registration scheme in enabling the industry to meet these obligations. It provides an analysis of two grower registration schemes designed to address biosecurity issues and finally provides a set of principles that can be used to guide the future development of a grower registration scheme for the vegetable industry.
