third step, forecasts <strong>of</strong> port visits by container ships are developed on the basis <strong>of</strong> thetotal containerised trade measured in teus <strong>and</strong> the average teus exchanged per containership.Further, the total containerised trade <strong>and</strong> the three years average proportion <strong>of</strong>international containerised trade are used to derive Australia’s internationalcontainerised trade in teus.Similarly, forecasts <strong>of</strong> non-containerised exports <strong>and</strong> imports are derived usingeconometric models with real gross domestic product (GDP) <strong>and</strong> gross nationalexpenditure (GNE), population <strong>and</strong> exchange rates as explanatory variables. Noncontainerisedexport <strong>and</strong> import forecasts are then added to derive the forecasts <strong>of</strong> totalnon-containerised trade. Total non-containerised trade <strong>and</strong> the three years averageproportion <strong>of</strong> international non-containerised trade are then used to derive the forecasts<strong>of</strong> international non-containerised trade. The average proportions are kept constant overthe forecast period.Total non-containerised trade is divided by the average tonnage <strong>of</strong> cargoes carried bynon-container ships to forecast the number <strong>of</strong> non-container ship visits over the forecastperiod.DATA AND THEIR SOURCESHistorical data on containerised <strong>and</strong> non-containerised exports <strong>and</strong> imports, emptycontainers, GNE, GDP, exchange rates, the trade weighted index <strong>and</strong> population used toestimate the econometric models were gathered from the <strong>Bureau</strong> <strong>of</strong> <strong>Transport</strong> <strong>and</strong><strong>Regional</strong> Economics (BTRE), Port <strong>of</strong> Brisbane Corporation (PBC), Sydney PortsCorporation (SPC), Port <strong>of</strong> Melbourne Corporation (PMC), Flinders Ports Pty Ltd(FPPL), Fremantle Ports (FP), the Association <strong>of</strong> Australian Ports <strong>and</strong> MarineAuthorities (AAPMA), the Australian <strong>Bureau</strong> <strong>of</strong> Statistics (ABS), Access Economics<strong>and</strong> the Organisation for Economic Co-operation <strong>and</strong> Development (OECD).Long-term forecasts <strong>of</strong> population <strong>and</strong> macroeconomic variables, which are the basis forthe shipping forecasts <strong>of</strong> this study, are obtained from the Australian <strong>Bureau</strong> <strong>of</strong>Statistics, Access Economics <strong>and</strong> the US Census <strong>Bureau</strong>.ASSUMPTIONSProportion <strong>of</strong> 40-foot containersThere has been an increase in the number <strong>of</strong> 40-foot containers used to export <strong>and</strong>import commodities at Australian ports. Approximately 38 per cent <strong>of</strong> total containersexchanged in Australia are 40-foot containers. However, 40-foot <strong>and</strong> 20-foot containersare not perfect substitutes. Heavy export commodities are being exported in 20-footcontainers, whereas 40-foot containers are used to import relatively light butvoluminous commodities. In this study, the proportion is assumed to gradually increasexvi
