## Conflicts And Limitations

- NDIS `participant_payments_aud_bn` uses accrual participant plan expenses where annual report financial statements are available. The 2024-25 value is $46.35bn accrual participant plan expenses; this differs from cash-basis public references to payments related to NDIS supports of about $44.9bn, so the CSV basis note states accrual plan expenses.
- The 2013 Commonwealth expenses cell is $383.35bn, below the plan's broad $400-900bn sanity band, because it is the official Budget Table 11.6 actual for 2012-13, the financial year ending in calendar year 2013.
- 2026 population uses latest ABS ERP at December 2025 because June 2026 ERP was not released as of the source release. 2026 labour force and CPI use latest May 2026 observations; 2026 GDP deflator uses March quarter 2026.
- CPI index cells before 2024 are empty because the current ABS monthly CPI index series begins in 2024. No bridging from the historical quarterly CPI series was performed.
