Sources

  • Headline, category breakdown, and largest claims: IPEA quarterly expenditure report, 2026Q01 — sourced from data.gov.au/data/organization/ipea.
  • Trend line: same source across 12 quarters (2023Q02 → 2026Q01). Median-MP comparison computed across all parliamentarians active in each quarter.
  • Identity: party, state, electorate, and role are read directly from the source CSV. From 2022Q03 onwards, MPs are tracked by a stable IPEA OfficeCode; earlier rows match by name.
  • Repayments sourced from the IPEA quarterly repayments CSV (available from 2022Q03 onwards). They are reported as a separate line, not netted off the gross total — ReportingPeriodId on a repayment marks when the money was paid back, not when the original claim was made. Adjustments are still not integrated. See methodology for the full list of caveats.
