Versions

publicdata.au keeps a new version each time the publisher changes the source file, and lists them all at https://publicdata.au/d/qld-traffic-census/versions.json. This repository tags each version it holds as v<date>, so load_dataset("National-Digital/qld-traffic-census", revision="v2026-08-06") always returns these rows.
