was requested by the then Minister for Natural Resources, Environment and Heritage to undertake a comprehensive assessment of seabed mining pursuant to section 5B of the Environment Protection Authority Act. The EPA was asked to address the actual or potential impacts of seabed mining activities on the Northern Territory (NT) environment and other resource industries, and methods for managing the impacts. This referral followed the introduction, on 6 March 2012, of a moratorium on seabed mining for a period of three years. The moratorium precludes, within NT coastal waters, the granting of titles permitting exploration for minerals or mining and the issuing of authorisations permitting mining activities. Work on the EPA’s review of seabed mining commenced immediately. Subsequently, in August 2012 the newly elected NT Government announced that the present EPA would be replaced by a new NT EPA. This report has been produced by the present EPA to inform future government decision-making and action on seabed mining. It summarises our current knowledge of seabed mining, associated impacts and management options, and includes recommendations for further work. Overall recommendation Although the EPA’s seabed mining review is incomplete, the preliminary analysis of relevant environmental and regulatory issues has produced useful findings. To date, there has been limited research into social, cultural and economic matters, but these will be important considerations in the development of NT-relevant management and regulatory frameworks. It is recommended the seabed mining review be continued, given the: • novel and technically innovative nature of seabed mining; • limited seabed mining knowledge and experience presently available within the NT and nationally; • many unknown problems likely to be encountered in securing sound environmental management and effective impact mitigation strategies; • increasing public expectations that new developments will be both economically and environmentally sustainable; • importance of identifying methods and processes for adequate protection of cultural heritage values; • benefits and certainty that specific policies and regulatory frameworks will provide for government, industry and
