Where "Postie" Comes From
"Postie" applies the "-ie/-y" suffix to "post-" (from "postal worker"), following the same pattern as "brickie," "tradie," and "sparky." The Australian National Dictionary documents these occupational "-ie/-y" nicknames as characteristic of Australian English — a consistent, productive pattern for creating affectionate informal titles for essential workers. Green’s Dictionary of Slang’s earliest clearly Australian citation for the word dates to 1904, in the Sydney Sportsman ("Maori man Ruenalf anxiously awaits the postie’s knock").
The postie on a small red motorbike or pushbike is an iconic Australian figure, particularly in suburban streets and country towns where daily mail delivery is a house-to-house ritual. Australia Post's motorbike-riding posties have been a fixture of Australian life for decades, making the word as much a cultural image as an occupational title.

How Aussies Actually Use It
"The postie" is used casually the way you'd refer to any regular local figure — "has the postie been yet?" is an extremely common household question.
The classic red Australia Post motorbike is so tied to the word that seeing or hearing one often prompts someone to say "there's the postie" without needing to explain further.
