Where available, the Data Stream(s) used to generate this Expert Assessment are accessible through the \"On-line Resources\" section of this record.\n\nDESCRIPTION OF THE PRESSURE\nDredging associated with the development or maintenance of port facilities around the coast of Australia is a necessary and unavoidable activity, vital to the continuity of the Australian economy.  Disposal of dredged material is mostly commonly by placement on the sea floor in specially designated areas. By volume this is by far the largest pressure on the marine environment due to \u201cdumped waste\u201d and over the period from 2011 to 2016 totalled in the region of 90 million cubic meters of sediment (Ports Australia 2014, 2015). The areas selected as disposal sites and the nature of disposed dredged material at sea are highly regulated to minimise the risk of marine organisms being exposed to toxic materials and that the sites chosen are the most likely to be minimally affected by the application of additional sediment (Ports Australia 2014).  Pressures arising from this practice include direct burial of biota as well as less direct impacts arising from resuspension of sediments placed on the sea floor.  While the footprint of disposal sites is relatively small on the scale of Australia\u2019s continental shelf, the area affected by remobilised material is potentially larger and less well known (McCook et al 2015). \nThe amount of dredged material disposed of at sea in the 5 year period up to 2016 has increased markedly over that reported up to 2011 (Fig. 1).  This is mainly due to two large port developments in north-western Australia\u2019s Pilbara region (Gorgon and Wheatstone). Generally there appears to have been a strong upward trend in volumes in the Pilbara over the past decade and two new project approvals have been granted for a further 34 million cubic meters at Anketell Port and 42 million cubic meters at Port Hedland of dredging and disposal in the region. Given the decline in resource development experienced since 2014, this trend may abate in the short term. \nDATA STREAM(S) USED IN EXPERT ASSESSMENT\nData used in assessment cover the entire continental coastal zone of Australia, and include all major ports.
