Overseas arrivals and departures: data quality issues
Passenger cards and visa information form the basis for overseas arrival and departure statistics. From July 1998, the Department of Immigration and Multicultural Affairs has revised incoming and outgoing passenger cards and associated procedures and systems. There have been some significant data problems, particularly in relation to main reason for journey and main state of stay for short-term visitors. A summary of data quality issues to date will appear in Appendix 2 of the December 1998 issue of Overseas Arrivals and Departures, Australia (ABS Catalogue No. 3401.0).
