Geographic representation of Greater Capital Cities (in red), international airports (having international air traffic in 2019, in green), and other regions (in blue) across Australia. The boundaries are delineated based on the 2021 SA2-resolution map of Australia. For visual clarity, some Australian islands are not shown.

The 3-letter code names for the annotated international airports are described in Table 4
