Search, filter, total and download the Australian government open data republished at < https://publicdata.au/>, where every version of a dataset is kept at a URL that never changes. Rows and totals come from the site's query API as typed, labelled 'tibble' data frames, and whole tables from its files in any of twelve formats. Map layers come as 'sf' objects, and rows that carry the code of an area join to the Australian Bureau of Statistics boundaries in one call. The 'DuckDB' file of any version can be attached over the web and queried in place with 'DBI' or 'dplyr'. Downloads can be kept in a cache, since a version never changes, the changes between versions are listed row by row, and the source file, fetch time and checksum of every version are on record. Every answer carries the version it came from and the attribution the publisher's licence requires, and citations come as 'BibTeX'. Any dataset the site serves works by its slug, so a new dataset needs no new release.
