How to read it

Fuel excise is often framed as a "road user charge", yet the revenue is consolidated into general revenue. This page lets you see both sides.

Data sources

  • ATO — published excise rates.
  • BP4 — state roads capital spending.
  • ABS — household fuel expenditure averages.

Caveats

  • Real-world fuel consumption varies widely; the calculator is illustrative.
  • Excise indexation means rates change twice a year.
