Usage notes[edit]

  • (good day): Used interchangeably with hello and hi, but more characteristically Australian/New Zealand, and perhaps the most informal of these options. Also used in the constructions G'day, mate (a greeting to a friend or acquaintance) and G'day, stranger (ironically, to a friend not seen in some time).
