The temporary fuel excise reduction that began on 1 April 2026 is designed to ease immediate cost-of-living pressure, with the ACCC publicly stating it expects the cut to be passed on to motorists as quickly as possible. For households watching every weekly expense line, that pass-through speed (and whether prices “stick”) matters just as much as the headline cents-per-litre figure.
From the lens of an accountant Box Hill families often ask the same question: “What does this actually change in my budget this week?” The practical answer is that the policy is real, but what you see at your local servo can vary in the short term, depending on how quickly sites cycle through stock purchased at earlier wholesale prices and how competitive pricing is in your area.
What changed from 1 April 2026
The excise rate was temporarily halved
The ACCC’s weekly monitoring report confirms fuel excise on petrol and diesel was temporarily halved from 52.6 cents per litre (cpl) to 26.3 cpl for three months from 1 April 2026, alongside a temporary heavy vehicle road user charge change for the same period.
The “all-in” relief being discussed is larger than excise alone
Because GST is applied on top of the fuel price, cutting excise also reduces the GST component. The ACCC report puts the combined impact of halving excise plus the associated GST effect at around 28.9 cpl. Separately, the ACCC has referenced a further change of about 5.7 cpl under the proposal announced on 2 April 2026, which is widely reported as taking the total relief being discussed to around 32 cpl for the period.
What it could mean for a typical weekly budget
If the full relief being discussed flows through (often described as about 32 cpl in public commentary and ACCC statements), the maths is straightforward:
- 50 litres per week → 0.32 × 50 = $16.00/week
- 65-litre fill → 0.32 × 65 = $20.80 per fill
- Two cars, 90 litres/week → 0.32 × 90 = $28.80/week
These are “best-case” savings assuming the reduction is fully reflected at the pump when you buy.
Why you might not see the full cut immediately
The ACCC notes that wholesale price movements typically flow through over time, often when retail sites replenish fuel. Its report also shows that on 1 April the average retail falls across major cities were meaningful but not uniform, with city-to-city reductions varying and some locations seeing much less movement on day one.
That’s why the ACCC is monitoring prices daily across capital cities and more than 190 regional locations, and has explicitly warned retailers against conduct that could mislead consumers about the true pass-through of savings.
Implications and who benefits
Households that drive the most (commuters, regional families, carers doing frequent trips) are positioned to benefit the most in dollar terms—provided they can access competitive pricing and shop around. For many, the practical budgeting win is treating the savings as deliberate cash-flow relief (e.g., offsetting grocery inflation, rebuilding a buffer, or pre-funding quarterly bills) rather than letting it disappear into higher discretionary spending.

Final thoughts
This is a short, time-boxed measure (commonly discussed as running through April to June 2026), and the real-world benefit will depend on how quickly competition forces full pass-through in your suburb and along your regular routes. Keep an eye on local price cycles, and treat any savings you do receive as an opportunity to stabilise your household cash flow while conditions remain volatile.
