This version is kept for as long as this site exists, and its URL can be cited. Its files change only for the reasons the terms give, and each change is recorded in its notes. The publisher's file is here as source.zip, byte for byte.
Files
data.csv464 MBCSV: UTF-8 without a byte-order mark, RFC 4180 quoting, one header row using the normalised field names. Opens in Excel, Numbers and Sheets.
data.csv.gz82 MBCSV (gzip): The same CSV, gzipped, at about a tenth of the size. curl, pandas, DuckDB and R read it directly.
data.duckdbDuckDB: One DuckDB database with a records table of typed columns, a fields table and a publicdata metadata table. It attaches read-only over HTTPS, so DuckDB, Python and R can query it without downloading it.
data.ndjson1.8 GBNDJSON: The first line is the provenance header, then one JSON object per line. For streaming and for tools that read line by line.
data.parquet85 MBParquet: Columnar and typed. The smallest download and the fastest to query. Reads directly in DuckDB, pandas, Polars, Arrow and Spark. The provenance header is in the file metadata.
data.sqlite427 MBSQLite: One database with a records table, a fields table and a publicdata metadata table. Open it with any SQLite client.
Excel is not offered because the table is over 1,048,575 rows, which is as many as a worksheet holds below its header row. JSON is not offered because the table is 1,753.3 MB as NDJSON, over the 50 MB limit for JSON.
SHA256SUMS holds the SHA-256 of every file in this version under the name it downloads as. Check what you downloaded with sha256sum -c --ignore-missing SHA256SUMS in the same folder. On a Mac, use shasum -a 256 -c --ignore-missing SHA256SUMS. Each list is signed by the deploy that wrote it: gh attestation verify SHA256SUMS --repo National-Digital/publicdata.au --source-ref refs/heads/main shows it came from this project's main branch.
