A PDF of the full Expert Assessment, including figures and tables (where provided) is downloadable in the "On-line Resources" section of this record as "EXPERT ASSESSMENT 2021 - Shipping (marine vessel activity)"

DESCRIPTION OF PRESSURE Australia as an island relies heavily on shipping for transportation of its domestic freight and international imports and exports. Australia relies on sea transport for 99 per cent of its international trade (by volume) [1]. In the 2017/18 financial year approximately 1554 million tonnes of cargo were loaded (+21.9% increase since 2013/14), and 155 million tonnes discharged (+2.6%) at Australian wharves by 5859 vessels (+6.5%) that made 34,117 port calls (+18.8%) [2]. As well as commercial vessels, many smaller vessels use Australian waters and provide an important recreational pastime for many Australians.
