This report presents 20-year forecasts of exports and imports of containerised and non-containerised freight and sea passenger movements through Australia's five largest capital city ports and, in aggregation, all other ports. The forecasts, which update those previously published by BITRE in 2002, 2006 and 2010, are driven by population, real income, exchange rates, import prices and export prices. The most recent economic outlook and population growth forecasts for Australia and its major trading partners have been used to derive the forecasts.
