Fuel excise discount halved from 1 July: expect petrol up ~16¢/L, and fill up before it lands

From today, Wednesday 1 July 2026, the federal government has halved the temporary fuel excise discount — from 32 cents a litre down to 16 cents a litre. In plain terms, the tax coming off every litre is smaller, so pump prices are expected to climb by around 16¢/L. That has not happened yet: as of today, prices are still steady, and the rise is likely to flow through over the next few days as stations restock. This is the reverse of the relief drivers saw in autumn, when the same measure cut prices by roughly 32¢/L.

What's changed

The 32¢/L discount was introduced earlier this year as cost-of-living relief after conflict in the Middle East pushed global oil sharply higher — regular unleaded hit records near $2.59/L and diesel climbed past $3.27/L. That relief was due to end on 30 June. Instead of removing it all at once, the government has extended a reduced version: a 16¢/L discount that runs from 1 July until 2 August. Treasurer Jim Chalmers said the step-down was deliberate, so there “wasn’t a big 32c change at midnight on the last day of June,” and confirmed the relief was always meant to be temporary and is not expected to be extended again.

How much, and when you'll feel it

Once it flows through, expect roughly 16¢/L more at the bowser — about $8–$9 on a 55-litre tank. But it did not jump everywhere at midnight, and on day one prices are holding steady. Prices lift as stations take delivery of fuel bought under the higher excise, which can take days depending on where you live. The ACCC’s Anna Brakey noted that “fuel retailers may not face higher costs straight away on 1 July, as new fuel supplies can take time to reach them.” The NRMA’s Peter Khoury put it more bluntly: “While it may not happen immediately, depending on where you live, Australians can absolutely expect fuel prices to go up by over 16 cents per litre over the next week,” urging families to fill up before it lands. That staggered rollout is the opportunity — for the next few days many stations will still be selling fuel bought under the bigger discount.

The ACCC is watching retailers

The consumer watchdog has put fuel retailers on notice not to use the excise change as cover for wider price hikes. “The ACCC expects that fuel retailers will not attempt to take advantage of this increase in excise,” Ms Brakey said, adding it would “closely examine fuel price movements and market behaviour, both in the lead-up to and following the increase.” The regulator has moved to weekly fuel price monitoring and says it “will not hesitate to take action if retailers make false or misleading statements about price movements or if there is evidence of anti-competitive behaviour” — including fines or court action if servos push prices beyond the 16¢ difference.

Should you fill up now?

For most drivers, yes — and because prices have not moved yet, you likely still have a few days. If your tank is below half, topping up before the rise reaches your area is the sensible call, because this is a known one-off increase rather than a normal cycle move. The catch is that the 16¢ lift will arrive station by station over the coming days, so live prices matter more than usual this week. Check your city’s forecast for the current fill-up recommendation, find the cheapest station near you to spot the sites that haven’t lifted yet, and keep an eye on the live fuel shortage tracker — pre-change rushes can leave some stations, especially for diesel, temporarily out of stock. PetrolPulse is tracking the flow-through daily and will update city recommendations as the rise lands.
