How Does Australia Compare?
Fuel Tax as % of Pump Price (OECD)
Key Facts
- Fuel excise is CPI-indexed — it rises automatically every 6 months without a parliamentary vote.
- GST applies on top of the excise — you pay tax on a tax.
- The excise was temporarily halved on 30 March 2022. The halved rate expires 30 June 2026.
- At full excise (52.6c/L), the government collects ~$12 billion annually from fuel excise alone.
- Fuel excise is not hypothecated to roads — it goes into general revenue.
- Australia imports ~90% of its fuel and holds only ~30-39 days of reserves (OECD standard: 90 days).
