Conventional risk assessment tools often fail to comprehensively evaluate these risks together, leading to stakeholder dissatisfaction, conflicts and poor biosecurity outcomes. To address this, we present a structured 7-step marine biosecurity risk framework. It systematically assesses incursion's ecological, economic, social and cultural impacts, encourages stakeholder engagement and promotes inclusive decision-making. Steps include defining contexts, setting objectives, estimating consequences, determining management options, evaluating trade-offs, implementing decisions, and communicating risks effectively. A simulation using Sabella spallanzanii illustrates its application. By integrating diverse perspectives and employing audience-centred communication plans, our framework facilitates informed and equitable decisions. It standardises data examination, aiding in addressing ecological, economic, social, and cultural integrity amidst non-indigenous marine species threats.9 pagesen© 2024 The Authors.
