The 70 Percent Surcharge: ACCC Targets Remote Australia's Fuel Bills

Something quietly significant happened earlier this month, and if you live or run a business anywhere outside the capital cities, it could end up in your wallet. The competition watchdog has fired off legal notices to a string of distributors operating in regional and remote Australia, demanding they justify fuel surcharges that in some cases tip past 70 per cent. And that's not a typo.

What's Actually Going On

Let's rewind. On 1 April 2026, the federal government slashed the fuel excise by 32 cents a litre, a temporary measure scheduled to run through to 30 June. The idea was straightforward enough: with diesel hovering between $2.75 and $3 a litre in parts of regional Australia, and petrol still well above pre-crisis levels in Western Australia, the Northern Territory and South Australia, Canberra wanted to take some heat out of the bowser.

But not long after that excise relief kicked in, the ACCC's complaints inbox started filling up. Small businesses servicing remote communities reported their suppliers had whacked them with fuel surcharges so steep they bore no resemblance to the actual rise in delivery costs. We're talking surcharges north of 70 per cent for businesses operating in places like Kalgoorlie, Alice Springs, Coober Pedy and Mount Isa.

So on 2 April, the day after the excise cut, the ACCC sent out what it calls substantiation notices to several distributors operating across SA, WA, QLD and the NT. The businesses had three weeks to explain themselves. Either prove the surcharge actually reflects your additional fuel costs, or face the consequences under the Australian Consumer Law.

The Backstory Most People Miss

Here's what most people don't realise. Regional fuel surcharges have been a feature of Australian commerce for decades. Anyone running a business in the outback knows that getting goods to remote communities costs more than getting them to Parramatta or Toowoomba. That's just the reality of moving freight across one of the most thinly populated continents on the planet.

But what the ACCC is digging into is something different. Some operators have apparently used the broader fuel crisis as cover to crank surcharges well above any reasonable cost increase. With diesel prices dominating the news, and motorists rightly furious about pump prices pushing through three dollars a litre, the assumption seems to have been that nobody would look too closely at the maths.

Wrong move.

ACCC Chair Gina Cass-Gottlieb has been unusually loud about this one. When the watchdog opened its broader enforcement investigation into Ampol, BP, Mobil and Viva Energy back in March, she pointed out that 'it is not our usual practice to publicly announce investigations, but given the significance of the issue' they felt compelled to act. The same energy is now being directed at distributors charging eyewatering surcharges in the bush.

How We Got Here

Quick history lesson. Australia, until very recently, was the only International Energy Agency member country without a government owned fuel reserve. That's a remarkable fact when you stop and think about it. Even Switzerland, a landlocked nation with no refining industry of its own, has held national fuel stocks for decades. Australia, sitting at the end of one of the world's longest shipping routes, was running on commercial inventory and a wing and a prayer.

That all changed on 6 May 2026, when Prime Minister Anthony Albanese unveiled the $14.8 billion Australian Fuel Security and Resilience Package. The plan includes a permanent government owned reserve of around a billion litres of diesel and aviation fuel, a $7.5 billion fuel and fertiliser security facility, and a lift in the Minimum Stockholding Obligation to roughly 50 days for diesel and jet fuel. Energy Minister Chris Bowen has been hammering the diplomatic phones too, securing alternative supply from the United States, Argentina, Algeria, South Korea, Brunei and Malaysia.

All of which is great. But it doesn't help the bloke running a general store in Tennant Creek right now, who gets handed an invoice with a fuel surcharge that turns a $4,000 freight bill into a $6,800 freight bill.

What This Means For You at the Bowser

Here's the practical upshot. If you're a regular punter filling up in a capital city, the latest ACCC weekly monitoring update from 8 May confirms what you've probably already noticed. Petrol prices in the five largest cities are down around 30 per cent from their crisis peak, and diesel is down about 25 per cent. International prices have stabilised over the past fortnight after weeks of whiplash, and most servos are now passing through that 32 cent excise cut as promised.

But for regional Australia, the picture is patchier. Diesel prices in remote outposts are still well above what city motorists are paying, and a chunk of that gap is genuine cost. Long haul road freight, smaller delivery volumes, fewer competing servos. All contribute. The ACCC's view is that these legitimate costs are fine. What's not fine is using 'fuel surcharge' as a convenient label for what's effectively a 70 per cent margin grab.

If you're a small business owner who's been hit with a fuel surcharge that doesn't quite smell right, the ACCC wants to hear from you. Substantiation notices are powerful instruments. They flip the burden of proof onto the supplier, who has to actually show their working. Get caught making claims you can't back up and the penalties can be serious, particularly now that maximum fines have been doubled from $50 million to $100 million per offence.

The Bigger Picture

What we're watching here is a regulator that has, frankly, lifted its game. The ACCC was criticised for years over a perceived hands off approach to fuel pricing. The same competition authority that famously couldn't pin down whether the four day price cycle in Sydney and Melbourne was anticompetitive or just convenient now has weekly monitoring obligations stretching to September, a major enforcement investigation into the big four suppliers, and public substantiation notices flying at remote distributors.

That's not nothing. Industry contacts tell me the major fuel players have been making a lot of phone calls to legal counsel lately, and the prevailing mood is decidedly less swaggering than it was twelve months ago.

For motorists, the takeaway is that the days of fuel pricing being a black box are slowly ending. There's more transparency than there's been in a generation, and a regulator that seems genuinely willing to use the tools it's got.

What To Watch

A few things worth keeping in mind as we head deeper into winter:

The fuel industry rarely gets the spotlight it deserves until something goes wrong. Right now, plenty has gone wrong all at once, and the regulator is finally swinging. Keep an eye on this space.
