In the event of intrusion of marine organisms of national importance, responsibility for the implementation of the original ACA rests with the relevant jurisdiction, in which personnel experienced in stroke development or assigned by marine organisms may not be available. There are no instruments that can be quickly implemented in the case of emergency measures, including assessing non-state market effects, and should therefore be a significant obstacle to a rapid and inexpensive response to marine intrusions. This project aims to fill this responsiveness gap by developing a BCA methodology that would guide the assessment of management options related to emergency response to parasitic infestations at sea. The main benefit of this project will be the increase in capacity in legal systems to complement a BCA with a consistent format and content for the intrusion of marine parasites in (critical) emergency situations. This will allow the NBMG to implement and implement a national emergency response to biosecurity incidents more quickly if deemed necessary. In the event of an outbreak or epidemic of national importance in Australia, an advisory committee of the National Biosecurity Management Group (NBMG) must make a series of recommendations on the technical feasibility of eradication based on the benefits and costs of such a response. This measure is part of the National Environmental Biosecurity Response Agreement (NEBRA). NeBRA contains a national framework for the benefits of biosecurity: cost analysis (the framework). While it does a detailed list of the essential requirements that a cost-of-demand analysis must take into account (see here), it does not contain specific methodology or tools that would provide a consistent approach to the implementation of an ACA.
