Versions

publicdata.au keeps a new version each time the publisher changes the source file, and lists them all at https://publicdata.au/d/au-births-by-age-of-mother/versions.json. This repository tags each version it holds as v<date>, so load_dataset("National-Digital/au-births-by-age-of-mother", revision="v2026-10-03") always returns these rows.
