Download the data

Everything behind the charts on this site, free to download and reuse. If we have got something wrong, this is how you prove it — which is rather the point of publishing it.

Please keep the caveats attached

Every row carries the publisher and URL of its primary source, and a caveat column where one applies. A figure separated from its caveat is how accurate data ends up producing inaccurate reporting — the funding numbers in particular have an upper-bound caveat that materially changes how they should be read.

An empty cell means the original source did not report that value. It does not mean zero. Nothing in these files has been estimated, interpolated or carried over from another release.

Federal voting-intention polls

148 records · 2025-06-01 to 2026-08-16

Every national poll in the tracker, as published by each pollster. Empty cells mean the pollster did not report that figure — they are never estimated.

Victorian voting-intention polls

60 records · 2023-02-18 to 2026-08-16

Every published poll of Victorian Legislative Assembly voting intention ahead of the 28 November 2026 state election. Empty cells mean the pollster did not report that figure — they are never estimated. One Nation is empty before 2026 because these tables carried no column for it, not because its vote was zero.

Preferred prime minister polling

147 records · 2025-07-01 to 2026-06-30

Every published preferred-prime-minister question, one row per leader per question. The `matchup` column records exactly who was offered, because a leader scores differently in a two-way and a three-way question and the two are not comparable.

Preferred premier polling (Victoria)

78 records · 2023-02-18 to 2026-08-16

Every published preferred-premier question ahead of the 28 November 2026 Victorian election. Each pairing is a separate series: the matchups change when a party changes leader.

Political party funding

1,920 records · 2024-25

Party income for the financial year, split into money traceable to a named source, public election funding, and money with no public source.

Victorian disclosed political donations

3,901 records · 2020-09-03 to 2026-07-29

Every donation disclosed to the Victorian Electoral Commission since 1 July 2020. Victoria's 21-day disclosure rule makes this near-live, unlike the federal annual returns. A record is 'reconciled' only once both the donor and the recipient have lodged; where one has not, that side's date is empty and the status says which. Not every donation is money — property, services and loans are valued, not paid.
