Executive Summary In 1997, the Australian and New Zealand Environment and Conservation Council (ANZECC) developed the Code of Practice for Antifouling andIn-water Hull Cleaning and Maintenance (hereafter referred to as the ANZECC Code). The ANZECC Code was developed out of dual concerns over the toxic effects of antifouling biocides on the marine environment and the potential of in-water ship hull cleaning practices to facilitate the establishment of marine non-indigenous species (NIS). The ANZECC Code describes practices that prevent the release of toxic chemicals and biofouling organisms into the marine environment. It prohibits in-water cleaning of vessels unless a permit is granted by the relevant management authority. The ANZECC Code is currently at variance with the International Convention on the Control of Harmful Antifouling Systems on Ships, ratified by Australia in 2007, because it accepts the use of tributyltin-based antifouling coatings. Over the past decade, progress has been made internationally with the development of non-biocidal antifouling coatings and novel hull cleaning technologies that reduce the risk of releasing contaminants or biofouling organisms into the marine environment. This report represents a literature review and analysis of the benefits and risks of in-water cleaning associated with currently available cleaning technologies, and considers whether an alternative approach to the current protocols within the ANZECC Code is appropriate.
