Australia's federal government is refunding coal companies about $6.2 billion for diesel fuel they burn while mining. This money comes from a program called the Fuel Tax Credit scheme, which refunds the fuel tax on machinery that never touches public roads. One coal mine alone—Whitehaven—is projected to use 2.5 billion litres of diesel over its lifetime. That's a lot of refunds.

The numbers are large. The entire FTC scheme cost $10.8 billion across all industries in 2025–26, but mining gets the biggest share. One company, BHP, received $622 million in diesel tax breaks in a single year. Looking ahead, the government expects to pay out $45 billion more in these refunds over the next four years.

Why the Cost Keeps Growing

Here's the problem: as coal seams near the surface run out, miners have to dig deeper. Digging deeper means moving more rock to get the same amount of coal. Moving rock requires diesel. So as mines get deeper, they burn more diesel, and the government's refunds grow—even though coal production itself isn't growing. One analysis found that diesel use in coal mining is rising faster than actual coal output. New equipment and better efficiency can help a little, but they can't stop this trend while miners keep digging deeper.

At the same time, the world is burning less coal. New coal power plants hit a 20-year low in 2024. So we have a situation where Australia is paying more to mine coal that the world wants less of.

Why Nothing Has Changed Yet

The government had started talking about cutting back these rebates before the Iran war broke out in May 2026. That war made energy security suddenly important, and politicians decided fossil fuels were too strategically important to mess with. The negotiations stopped.

But there's a bigger point here. The Fuel Tax Credit was designed with logic: since road taxes pay for roads, vehicles that don't use roads shouldn't pay the tax. That makes sense. But when you're giving billions in refunds to mining companies that dig up coal—and coal burning creates climate damage that the same government is trying to fix through other policies—you have a real contradiction. The government hasn't sorted this out. Whether the pause in reform talks becomes permanent is the question now.
