This record provides an overview of the scope and research output of NESP Marine Biodiversity Hub Project E3 - "Microplastics in the Australian marine environment". No data outputs are expected for this project. -------------------- A literature review will firstly identify key marine microplastics research and policy development internationally, with a focus on research that is contextual to microplastics in the Australian marine environment From this literature review, an options paper will be developed to explore the most feasible and impactful policy approaches for the Australian context to reduce both intentionally added and not intentionally added microplastics in the marine environment (it would be beneficial to understand the policy options that can address both categories of microplastics because the options are different). These two reports would form the basis of a one day workshop that will draw together policy-makers, researchers and relevant industry peak bodies to discuss and recommend policy and other options to limit the release / impact of microplastics in the environment. A workshop report will be drafted to summarise findings, recommendations, and next steps (including identifying gaps in both science and policy will inform any future work required). The report will provide evidence to underpin the development of national policy aimed at reducing microplastic pollution, including by identifying priority actions to deliver Australia’s 2018 National Waste Policy .

This record provides an overview of the NESP Marine and Coastal Hub small-scale study - "Microplastics in South Eastern Australian coastal waters: synthesising current data and identifying key knowledge gaps for the management of plastic pollution". For specific data outputs from this project, please see child records associated with this metadata. -------------------- Plastic pollution is pervasive in coastal environments globally and in Australia. Due to their small size, microplastics (pieces <5mm) are readily ingested by marine organisms and potentially accumulate across food webs, raising concerns for biota, ecosystem services and human health. Yet, to define guidelines and support policy actions that curb microplastic pollution, managers and decision-makers lack clear, synthesised information on this multifaceted issue, including on occurrence, sources, and pathways of microplastics in coastal and marine environments. This project produces a synthesis of current data on microplastics in South Eastern Australian coastal waters (i.e. South Australia, Victoria and New South Wales) and identify key knowledge gaps for the management of plastic pollution. Outputs • List of compiled datasets relating to microplastics in SE Aus waters [spatial dataset] • Scoping document synthesising the information available on the presence of microplastics in coastal marine environments in South Eastern Australia, its potential sources and pathways [written]
