Overseas Arrivals and Departures: Australian Border Movements

Overseas Arrivals and Departures (OAD) data from the Australian Department of Home Affairs records traveler movements through Australian airports and seaports. The dataset, last updated in March 2026, uses a sampling methodology and revised data collection following the retirement of paper-based Outgoing Passenger Cards in July 2017. It counts multiple movements of individual persons and differs from other migration program or visa grant statistics.

Use Cases

• Modeling tourism seasonality based on visitor arrival and departure movements.
• Analyzing long-term migration trends by comparing settler arrival statistics.
• Forecasting demand for services by tracking international student and visitor flows.

Strengths

• Data is published under a CC-BY-4.0 license, facilitating reuse.
• Methodology has been reviewed and revised by the Australian Bureau of Statistics.
• Dataset was republished in March 2024 following a privacy and risk assessment.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data uses a sampling methodology and excludes some non-Department sources, which may affect granularity.
