Data on freight vehicle and commodity flows in Australia are poorly covered by official statistics, yet for many strategic purposes the analyst requires a nationwide picture of commodity flows. FreightInfo satisfies this requirement. FreightInfo is a database based on a combination of assembly techniques: the expert development of secondary data from existing national data collections, the systematic identification of major flow sources and sinks, and a rolling program of field data collection from freight consignors, consignees, and carriers. These are integrated into a coherent and consistent database covering the whole of Australia by all modes. A description of FreightInfo is presented, its creation is described, and some aggregate results relating to Australia are presented.
