Files

• data.arrow157 MB Arrow: Arrow IPC file (Feather v2), zstd compressed, with the provenance in the schema metadata. Memory-maps in pyarrow, Polars, Arrow JS and R without parsing.
• data.csv463 MB CSV: 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-metadata.json5.1 KB
• data.csv.gz82 MB CSV (gzip): The same CSV, gzipped, at about a tenth of the size. curl, pandas, DuckDB and R read it directly.
• data.duckdb DuckDB: 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 GB NDJSON: The first line is the provenance header, then one JSON object per line. For streaming and for tools that read line by line.
• data.parquet99 MB Parquet: 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 MB SQLite: One database with a records table, a fields table and a publicdata metadata table. Open it with any SQLite client.
• manifest.json1.5 KB
• schema.json3.4 KB
• schema.sql2.6 KB
• source.zip79 MB

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 over 2,000,000 rows, too many for one document a reader parses at once.

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.
