Australia Has Just 28 Days of Petrol and Nobody Seems Concerned

Here's something that should probably be making more headlines: if the ships stopped arriving tomorrow, Australia would run out of petrol in less than a month. Twenty eight days, to be precise. Diesel? Twenty four days. Jet fuel? A mere twenty days before every plane in the country is grounded.

These aren't figures from some fringe think tank. They come directly from the Department of Climate Change, Energy, the Environment and Water. And while most Australians were focused on Christmas shopping and holiday road trips, the Maritime Union of Australia issued a stark warning: the nation is perilously exposed to supply shocks that could, quite literally, shut down the country.

From Twelve Refineries to Two

To understand how we got here, you need to go back a few decades. In the 1970s, when Australia signed up to the International Energy Agency's treaty requiring member nations to maintain 90 days of oil reserves, we had no problem meeting the benchmark. Back then, roughly a dozen oil refineries operated across the country, each with substantial storage facilities attached.

Fast forward to 2025 and the picture looks dramatically different. We're down to just two refineries. Ampol's Lytton facility near Brisbane and Viva Energy's operation in Geelong. That's it. The BP refinery in Kwinana closed in 2021. ExxonMobil's Altona plant in Victoria shut the same year. Both were converted into import terminals, which tells you everything about where the industry is headed.

The result? Around 91 per cent of Australia's refined fuel now arrives on ships, primarily from Singapore, South Korea, and Japan. Every litre of petrol you pump at your local servo has likely travelled thousands of kilometres before reaching the bowser.

The 90 Day Rule Australia Can't Meet

Here's where it gets particularly uncomfortable. As an IEA member, Australia is legally obligated to maintain oil reserves equivalent to 90 days of net imports. It's not a suggestion or a guideline. It's a treaty commitment dating back to 1974, designed to protect member nations from supply disruptions like the oil shocks of the 1970s.

Australia hasn't met this requirement since 2012. Not once in thirteen years. As of July 2025, official figures show reserves equivalent to just 49 days of net imports, close to record low levels reached in 2017.

To put this in perspective, the average among IEA member nations that are net oil importers sits at 141 days. Japan and South Korea each hold reserves exceeding 200 days. Even New Zealand, our closest neighbour and the country with the second lowest reserves after Australia, manages 92 days. We're dead last among 28 nations.

What Would Actually Happen

It's worth being specific about what a major supply disruption would look like. Not because it's likely to happen next week, but because understanding the stakes helps explain why some defence and energy experts are genuinely alarmed.

Government modelling suggests that in a total supply stoppage, Australia's GDP would fall by 31.8 per cent over six months. That's not a typo. Nearly a third of the economy would evaporate.

The practical impacts would hit almost immediately. Within days, fuel allocation would begin. Within weeks, supermarket shelves would empty as trucking networks ground to a halt. Pharmacies would struggle to maintain supplies. Freight between states would face severe disruption. Every plane would be grounded. Emergency services would be forced to ration fuel for critical responses.

Loss of fuel wouldn't just affect motorists filling up in Sydney or Perth. It would cripple the fundamental logistics that keep the country functioning, from medical supplies reaching regional hospitals to food reaching remote communities in the Northern Territory and Western Australia.

The Threats Are Real, Not Theoretical

You might reasonably ask: what are the chances of such a disruption actually occurring? The honest answer is that we've come closer than most people realise, and the risks are increasing.

Russia's invasion of Ukraine sent energy markets into chaos globally. Houthi attacks on oil tankers in the Red Sea have disrupted shipping routes that Australia depends on. Iran has repeatedly threatened to close the Strait of Hormuz, through which roughly 20 per cent of the world's oil passes daily.

Australia's fuel security isn't hypothetical anymore. It's being tested by events happening right now on the other side of the world. And because the supply chain stretches through some of the planet's most strategically contested waterways, from the South China Sea to the Strait of Malacca, any significant regional conflict could leave us scrambling.

What the Government Is Actually Doing

To be fair, Canberra hasn't ignored the problem entirely. There's a suite of programs designed to address fuel security, though whether they're adequate is a matter of considerable debate.

The Fuel Security Services Payment program provides up to $2.3 billion through 2030 to keep our two remaining refineries operating. Without this subsidy, both Ampol and Viva Energy would likely close, pushing our import dependency to effectively 100 per cent.

The Minimum Stockholding Obligation, introduced in 2023, requires refineries and major importers to maintain baseline stocks. For petrol, that's 27 days. For diesel, it's 32 days. The theory is sound, but the numbers still fall well short of the 90 day IEA benchmark.

The government has also established storage agreements with the United States, counting American held reserves as part of Australia's emergency stockpile. Critics argue this is creative accounting rather than genuine security, since those reserves sit on the other side of the Pacific, not in Melbourne or Adelaide where they'd actually be needed.

When asked about the situation recently, Climate Change and Energy Minister Chris Bowen's office responded that Australia has more aviation fuel, petrol, and diesel stored than at any time in the past 15 years. That's technically true, but it sidesteps the fundamental problem: we're still woefully short of international standards and more exposed than almost any comparable economy.

What This Means for You at the Bowser

In normal times, which is to say most of the time, none of this affects your daily fill up. Petrol arrives reliably at servos across New South Wales, Queensland, Victoria and everywhere else. Prices fluctuate with global oil markets and the Australian dollar, but supply isn't an issue.

The concern isn't about tomorrow or next month. It's about what happens when something goes wrong in a world where things are increasingly going wrong. A major conflict in the Indo Pacific. A natural disaster that closes key ports. Another pandemic that disrupts global shipping. Any of these scenarios could expose Australia's fuel vulnerability in ways that would affect every motorist, every trucking company, every family doing the weekly grocery shop.

For regional Australians in places like Broken Hill, Alice Springs, or Kalgoorlie, the situation is particularly acute. These communities depend entirely on long supply chains that begin with imported fuel. They'd feel the pinch first and hardest.

The Bigger Picture

Australia faces a genuine strategic dilemma. Our economy and way of life depend almost entirely on imported fuel, yet we've structured our reserves and infrastructure around the assumption that those imports will always arrive on time. Former independent senator Rex Patrick called it years of government neglect of a national security issue. He's not wrong.

The EV transition will eventually reduce our petrol dependency, but that's a decades long process. In the meantime, diesel remains essential for trucks, farming equipment, and mining operations that form the backbone of the Australian economy. Aviation fuel has no practical electric alternative on the horizon.

Some analysts argue we should simply accept our fuel import dependency as a fact of life in a globalised economy. Others point out that no military strategist would design a nation's energy security around the assumption that everything will always work perfectly.

What You Should Actually Know

The practical takeaways from all this are limited but worth noting.

First, fuel prices in Australia will always be vulnerable to global disruptions because we import so much. When something happens in the Middle East or Southeast Asia, expect it to eventually show up at your local Ampol, BP, or Shell station.

Second, the government's fuel security programs are keeping our last refineries alive, but just barely. If those subsidies ever end without alternative arrangements, our import dependency would become total.

Third, while a complete supply shutdown remains unlikely, shorter disruptions causing temporary price spikes and localised shortages are entirely possible. Keeping your tank above quarter full isn't paranoid. It's prudent.

The fuel industry rarely makes headlines until prices spike or something goes wrong. But understanding the structural vulnerabilities in Australia's fuel supply puts you ahead of the curve. Keep an eye on this space. The 28 day buffer between normal life and genuine crisis is thinner than most Australians realise.
