This first edition details the regulatory frameworks governing the management of biofouling on ships operating in Australian and New Zealand waters. Australia’s layered federal and state regulatory systems combined with diverse port ownership structures present significant compliance challenges for shipowners, operators and agents. New Zealand’s 2023 Craft Risk Management Standard (CRMS) for Vessels is the strictest biofouling management regime in the world, backed by rigorous enforcement and the potential for substantial penalties for non-compliance.

The publication also examines the AFS Convention, port entry requirements, penalties for non-compliance and the impact of biofouling on ship hydrodynamics and operating costs. It provides practical guidance on ship inspection and cleaning, supported by a comprehensive set of data sheets for in-water hull cleaning companies, including location maps. The appendices provide a set of official checklists for in-water cleaning, the MPI Vessel Checklist and Reporting Form, the MPI Biosecurity Pre-Arrival Report, and commentary on the 2023 Biofouling Guidelines.

This is an essential guide for maritime professionals operating in or entering Australian and New Zealand waters, providing clear insight into compliance obligations and effective preparation for port entry, helping to minimize disruption, delays and unexpected costs.

Introduction

Foreword

Australia is the world's largest island nation, surrounded by some of the most iconic marine waters in the world. We have the third largest maritime jurisdiction in the world, with an EEZ of approximately 10 million square kilometers. As a nation, we are justifiably proud of our marine estate, the biodiversity it supports and the connection it provides to the region and the world for our people and industries.

The Australian Government takes protection of these unique natural assets very seriously and has implemented strict maritime biosecurity regulations that serve as a defense against the translocation of non-indigenous marine species.

Australia has a complex and layered system of federal and state government regulation as well as private and public port ownership structures. To ensure shipowners, operators and agents are complying with required entry requirements in an efficient and timely manner, it is essential to understand the framework well.

MIAL is proud to partner with Witherbys and the New Zealand Shipping Federation and endorse this invaluable guide to Australia and New Zealand Biofouling and recommend this as a resource to anyone in the maritime industry with an interest in engaging with Australia and New Zealand.

As a distant island nation, New Zealand has a long history of strict biosecurity rules to prevent harm to our agriculture-based economy and numerous native species of flora and fauna.

New Zealand has developed a mature biofouling regime that is more restrictive than what exists in most other countries. Under this biofouling regime, the Craft Risk Management Standard (CRMS), government officials can require a hull inspection, change a vessel's itinerary, require removal of biofouling within 24 hours, or order a vessel to depart New Zealand waters if they have reasonable grounds to suspect a craft contains any unwanted organism.

It is important that ship owners, operators and shipping agents understand the complexity of the CRMS, what is required to demonstrate compliance, and the strictness with which it is enforced if they are to avoid unnecessary disruption, lost time and cost.

Witherby's Australia and New Zealand Biofouling book is an indispensable guide for owners, operators and agents seeking to navigate New Zealand's biofouling regime, and is highly recommended reading.
