Oil Hits $100, Cattle Stranded at Saleyards, and Canberra Opens the Reserves. Australia's Fuel Crisis Just Entered a New Phase

Four days ago, I wrote that regional servos were running dry while the government insisted everything was fine. Two days ago, I covered the IEA's record 400 million barrel release and the quiet relaxation of fuel quality standards.

Since then, things have not improved. They have accelerated.

Brent crude broke through US$100 a barrel on Wednesday night, closing at US$100.46, up 9.2 per cent in a single session. Iran's newly appointed supreme leader, Mojtaba Khamenei, used his first public address to declare that the Strait of Hormuz "must remain closed" as a tool to pressure the enemy. The federal government responded by releasing 762 million litres of fuel from domestic reserves and cutting minimum stockholding obligations by 20 per cent.

And at Gunnedah saleyards in New South Wales on Thursday, 6,500 head of cattle needed 72 B doubles to move them. That requires roughly 130,000 litres of diesel. The diesel was not available.

This is no longer a supply disruption. This is a structural crisis playing out in real time across paddocks, saleyards, freight depots, servo forecourts and kitchen tables from Cairns to Geelong.

The $100 Barrel and What It Means at the Bowser

Let's start with the number that drives everything else.

Brent crude, the international benchmark that determines what Australia pays for imported fuel, closed at US$100.46 on March 12. It had been sitting around US$67 in late February. That is a 50 per cent increase in two weeks.

On March 9, the day the Strait of Hormuz effectively closed, Brent hit a session high of US$119.50. It has since pulled back on the IEA reserve release announcement, but the fundamental problem has not changed. Roughly 20 million barrels per day of crude and refined products normally transit through Hormuz. With exports through the strait below 10 per cent of pre conflict levels, the world is losing 18 million barrels a day of supply.

The rule of thumb is straightforward. Every US$10 rise in crude adds roughly 10 Australian cents per litre at the pump. Crude has risen roughly US$33 since late February. Do the maths.

Right now, Petrolmate is tracking these national averages:

State by state for unleaded:

Diesel is the bigger story. National average 254.1 cents, but regional prices are pushing well past 280 and in some remote locations beyond 300. The Northern Territory is averaging 264.4 cents for diesel, and that is only the stations that still have stock.

Analysts at The Conversation project a further 40 cent rise is possible if the disruption persists, which would push unleaded past 260 cents and diesel past 290 in most capital cities. A 60 litre fill of unleaded would cost roughly $156. That is $24 more than a month ago.

Iran's New Leader Slams the Door

The geopolitical picture deteriorated significantly on March 12 when Mojtaba Khamenei, Iran's newly appointed supreme leader, issued his first public statement. He did not appear on camera. The statement was read by a news anchor on Iranian state television. But the message was unambiguous.

The "lever of blocking the Strait of Hormuz must definitely continue to be used," Khamenei said, according to Bloomberg. He demanded the immediate closure of all US military bases in the Middle East and warned of further attacks.

Khamenei, 56, succeeded his father Ayatollah Ali Khamenei, who was killed in an Israeli strike early in the conflict. Whether the statement was actually authored by Mojtaba or crafted by the IRGC apparatus around him is unclear. What matters for fuel markets is the signal: there will be no voluntary reopening of Hormuz from the Iranian side.

Iraq and Kuwait have already cut oil output by 70 per cent and declared force majeure due to storage exhaustion. They physically cannot export because there is nowhere for the crude to go with the strait closed.

For Australia, which sources the vast majority of its refined fuel from east Asian refineries that themselves depend on Middle Eastern crude transiting Hormuz, this is not an abstract diplomatic development. It is a direct threat to supply continuity.

762 Million Litres and a 20 Per Cent Cut to Reserves

The federal government's response came on March 13 when Energy Minister Chris Bowen announced two significant measures.

First, the Minimum Stockholding Obligation for diesel has been reduced from 2.7 billion litres to 2.2 billion litres. For petrol, it drops from 1 billion litres to 700 million litres. Combined, that frees up to 762 million litres that importers and refiners were previously required to hold in reserve.

Second, Ampol has committed to prioritising that released fuel for regional areas experiencing shortages, using the wholesale spot market to channel supply to independent distributors who have been cut off from major terminals.

The maths here deserves scrutiny. Australia consumes approximately 160 million litres of fuel per day. Releasing 762 million litres sounds enormous until you realise it represents fewer than five days of national consumption. And it does not create new supply. It lowers the safety buffer.

Remember, Minister Bowen told Parliament earlier this week that Australia holds 36 days of petrol, 34 days of diesel and 32 days of jet fuel. The IEA standard is 90 days. We were already at a third of where we should be. Now we are deliberately drawing that buffer down further.

Macquarie University's analysis this week posed the question directly: what happens when Australia's 36 day petrol supply runs out? The answer is not reassuring. Australia has no government owned strategic petroleum reserve. Unlike the United States, Japan, or South Korea, our stockpile is entirely held by private companies. The Minimum Stockholding Obligation tells those companies how much they must keep on hand. When the government cuts that obligation, it is essentially asking companies to sell their safety margin.

The Animal Welfare Crisis Nobody Saw Coming

This is the story that should be leading every evening news bulletin but is not.

At Gunnedah saleyards in the New England region of NSW, 6,500 head of cattle were yarded on Thursday. Moving that many animals requires approximately 72 B doubles. Each B double carries around 90 head and burns roughly 1,800 litres of diesel per trip. Total fuel requirement: about 130,000 litres.

The fuel was not there.

The New England Times reported that the diesel shortage is creating both logistical and animal welfare issues involving cattle movements. When livestock is yarded for sale, there are legal and ethical obligations around how long animals can be held, how they must be watered and fed, and when they must be moved. If the trucks cannot be fuelled, the cattle cannot be moved. If the cattle cannot be moved, welfare standards start to degrade.

This is not hypothetical. It is happening right now in one of Australia's major livestock regions.

Beef Central reported that the crisis extends well beyond Gunnedah. Feedlots across Queensland and northern NSW are reporting tightening diesel supply for the trucks that deliver feed and transport finished cattle. Livestock agents are warning that if the situation continues beyond next week, some operators will have no choice but to hold cattle on properties where feed may not be adequate.

The National Farmers Federation described the situation as a "perfect storm" that threatens food prices. When diesel runs short, it is not just transport that stops. Irrigation pumps need diesel. Grain dryers need diesel. Refrigerated transport needs diesel. The food supply chain is a diesel supply chain, and that chain is stretching to breaking point.

In Western Australia, the Nationals have warned that fuel shortages are putting farmers and the entire food supply at risk. Perth prices have reached $2.37 per litre, a 23 per cent premium over baseline.

The Trucking Industry: $500 a Day in Extra Costs

Australia moves 75 per cent of its domestic freight by road. When diesel goes up, everything goes up.

Big Rigs reported that experienced truck driver Adam Craig warned diesel prices approaching $3 per litre will force operators to park their trucks. "If diesel gets to $3 per litre, businesses will start parking up," he said. That is not an exaggeration. Most trucking operators run on profit margins below 3 per cent. A 30 cent per litre diesel increase on a truck burning 2,000 litres a week adds $600 a week in costs. Over a fortnight, that is more than $1,200 per truck.

The Australian Trucking Association has been direct: consumers and businesses must be ready to pay more. Rising fuel prices are adding roughly $500 per day in additional operating costs for each truck on average. For a fleet of 20 trucks, that is $10,000 a day. $70,000 a week. Nearly $300,000 a month.

The flow through to consumer prices is inevitable. Every 1 cent rise in diesel lifts freight rates by approximately 0.25 per cent across long haul routes. Diesel has risen roughly 40 cents in two weeks. That translates to a 10 per cent freight rate increase that will show up in the price of everything from milk to building materials over the coming weeks.

The Queensland industry has called for fuel price stability, but stability requires supply, and supply requires an open Hormuz or alternative sources that have not yet materialised at scale.

Victoria's Price Cap: Three Days In

Victoria's Fair Fuel Plan daily price cap took effect on March 10. It is the most significant state level intervention in fuel pricing in Australian history.

The mechanics are straightforward. Every fuel retailer in Victoria must submit their maximum price for each fuel grade by 2pm each day. That capped price is published on the Servo Saver comparison app by 4pm. From 6am the following day, that cap applies for 24 hours. Retailers can lower their price during the day. They cannot raise it.

Breach penalties are more than $3,000 per offence, or more than $24,000 if taken to court.

Three days in, Victoria is tracking as the second cheapest state for unleaded at 221.5 cents, just behind Tasmania at 221.2. Whether the cap is responsible or whether Victoria was simply at the bottom of its price cycle is impossible to say this early. The real test will come when wholesale prices rise and retailers face the choice between absorbing the increase or capping at a price that compresses their margin to nothing.

The ACCC, meanwhile, has ramped up its own scrutiny. CEO Sarah Proudfoot sent letters to eight major fuel retailers warning that the regulator does not expect to see "uncharacteristic and abnormal" price increases. The federal government has doubled maximum penalties for false and misleading conduct and cartel behaviour from $50 million to $100 million per offence. And the ACCC will now report weekly with a focus on unusual price spikes.

Whether regulatory threats change retailer behaviour when their own wholesale costs are genuinely surging is another question entirely.

The EV Pivot Nobody Expected This Fast

Here is a number that caught my attention.

Research commissioned by Green.com.au and conducted by Primara Research in March 2026 found that one in four Australians, 25 per cent, is now considering switching to an electric vehicle for the first time. Before the crisis, that figure was 7 per cent. Among 25 to 34 year olds, it is 42 per cent.

Battery EVs hit a record 11.8 per cent of new car sales in February. Searches for used EVs jumped 30 per cent in a single week. The Climate Council noted that 98 per cent of Australia's vehicle fleet still runs on petrol or diesel, but the transition in buyer sentiment is accelerating faster than anyone predicted.

Regional media is tracking the shift too. The Moree Champion reported a surge in local EV interest driven specifically by fuel costs. That is significant because regional Australia has traditionally been the most sceptical market for electric vehicles, citing range anxiety and lack of charging infrastructure.

None of this helps the farmer who needs diesel for his header this week. But it signals a structural shift in how Australians think about energy dependence. A week ago, fuel security was a policy wonk's talking point. Now it is a kitchen table conversation influencing car buying decisions.

Across the Ditch

New Zealand is tracking the same trajectory with fewer buffers. Petrol prices have risen past NZ$2.70 per litre in some areas, up more than 20 cents in a week. The government has refused to cut fuel taxes, arguing it would undermine road maintenance funding.

The freight industry in New Zealand is preparing for diesel to breach NZ$3.00. Greater Auckland's analysis noted that fuel price spikes historically accelerate public transport usage and cycling in urban areas, but New Zealand's regional freight network has no alternative to diesel.

The Election Wildcard

With the federal election approaching, fuel has become the defining cost of living issue. Peter Dutton has promised to halve the fuel excise for 12 months, dropping it from 50.8 cents to 25.4 cents per litre. The Coalition estimates savings of $14 a week for a one car household. The price tag is $6 billion.

Labor has not matched the pledge, pointing to its $17 billion tax cuts package and arguing that a temporary excise cut is exactly what Scott Morrison did in 2022. It "disappeared because it was time limited," the government says.

The Greens continue to argue that the crisis proves the case for renewables and have called for the EV discount to be maintained. Jacqui Lambie has described both major parties as having "dropped the ball for years." One Nation wants the excise halved permanently.

None of these positions address the immediate crisis. A 25 cent excise cut does not fix a broken supply chain. Tax cuts do not put diesel in a B double at Gunnedah. And transitioning to renewables, while correct as a long term strategy, does not solve a crisis that is measured in days and weeks, not years.

Where This Goes From Here

Five things to watch.

First, Brent crude. If it holds above US$100, Australian pump prices will continue climbing. If it pushes back toward US$119, the 40 cent further rise that analysts are projecting becomes almost certain. The IEA's 400 million barrel release provides a short term ceiling, but as I wrote on Wednesday, that covers roughly 22 days of the Hormuz shortfall. Not 22 weeks.

Second, the reserve drawdown. The 762 million litre release buys time, but it also lowers Australia's already inadequate safety buffer. If the crisis extends past April, the government will face a choice between releasing more reserves and risking genuine depletion, or maintaining reserves while regional Australia goes without.

Third, animal welfare. The livestock transport crisis at Gunnedah is a canary in the coal mine. Autumn is the busiest period for cattle sales across the New England and Northwest Slopes. If diesel remains scarce through March and into April, the welfare implications for livestock that cannot be moved, fed or processed will become severe.

Fourth, the freight cascade. The $500 per day per truck cost increase has not yet fully flowed through to consumer prices. When it does, over the next two to four weeks, Australians will see the fuel crisis reflected in the price of bread, milk, meat and building materials. The CPI impact of a sustained 40 cent diesel increase across the national freight network is not trivial.

Fifth, the election. Both major parties are now locked into fuel as a central campaign issue. Whether that produces genuine structural reform, a national strategic reserve, mandated regional distribution protocols, diversified supply agreements, or just short term cash splashes will tell you everything about how seriously Canberra takes energy security when the cameras are rolling.

The Structural Question

I keep coming back to the same point because it keeps being true.

Australia imports 90 per cent of its liquid fuel. We have two refineries. We have never met the IEA's 90 day reserve requirement. Our Minimum Stockholding Obligation, the one we just cut by 20 per cent, sets the floor at 27 to 32 days when the international standard is 90.

We knew this was a vulnerability. We have known for decades. Every parliamentary inquiry, every strategic review, every defence white paper that touched on fuel security reached the same conclusion: Australia is dangerously exposed to maritime supply chain disruptions.

And now a disruption has arrived. Not a hypothetical exercise. Not a war game. An actual closure of the world's most important oil chokepoint, by a regime that has publicly stated it intends to keep it closed.

The 762 million litre release is necessary. The IEA's 400 million barrels are necessary. Victoria's price cap is necessary. The ACCC's scrutiny is necessary. All of it is necessary.

None of it is sufficient.

The cattle at Gunnedah still need diesel. The truckie at Toowoomba still needs diesel. The farmer outside Dubbo still needs diesel. And right now, the system that is supposed to deliver it to them is failing.

That is not a supply disruption. That is a structural failure. And pretending otherwise does not make it less true.
