6.53 In Australia's international merchandise trade statistics Australian ports are derived from the UN/Locodes provided on the export and import declarations. The ABS corresponds each five letter UN/Locode to a 3 digit international merchandise trade Australian port code (e.g. UN/Locode AUSYD corresponds to ABS Australian port code 101 with label 'Sydney'). The ABS Australian port code list includes combined offshore ports for Western Australia and the Northern Territory. These combined ports include a number of offshore facilities. For exports, the Australian port is the port of loading and for imports the Australian port is the port of discharge. The ABS maintains the international merchandise trade Australian port classification.
