Australia’s fuel threat spreads beyond Hormuz as Saudi oil route comes under attack

An apparent improvement in oil movements through the Strait of Hormuz has been overshadowed by attacks directed at Saudi Arabia’s alternative export corridor—just as Australia begins another argument over reducing fuel tax.

Australia’s fuel crisis has entered a more complicated and potentially more dangerous phase.

The immediate threat is no longer confined to the Strait of Hormuz. Yemen’s Houthi movement has claimed missile and drone attacks against sites in Saudi Arabia, including an Aramco facility at Yanbu—one of the kingdom’s most important oil-export centres on the Red Sea.

Flames and a large column of smoke were independently observed near Riyadh airport following explosions and emergency alerts, although Saudi authorities have not confirmed the claimed damage at Yanbu.

The distinction is important. An attack has been claimed, but a lasting interruption to Saudi oil exports has not yet been established.

Nevertheless, the development exposes a larger vulnerability in the world’s oil-supply system.

While traffic through the Strait of Hormuz remains restricted, Saudi Arabia’s pipelines and Red Sea terminals provide an alternative route by which some Gulf oil can avoid the strait. If infrastructure serving that route is also threatened, the world does not merely lose another individual facility. It loses part of the system designed to compensate for the original disruption.

Australia, which imports most of the petroleum products it consumes, is particularly exposed to any widening of that disruption.

Some improvement through Hormuz

There has been qualified progress in the Strait of Hormuz.

The head of United States Central Command, Admiral Brad Cooper, says the principal transit lanes have been cleared of mines and that the volume of oil, gas and cargo moving through the strait during the past two weeks has reached its highest level in six months.

He said US forces had supported the movement of one billion barrels of oil through the waterway over the past two months.

That is encouraging, but it does not mean the crisis has ended.

Independent shipping monitors reportedly continue to record traffic well below pre-war levels. Iran retains the capacity to threaten vessels, insurers continue to price in extraordinary risks and shipping companies must consider the safety of their crews as well as the availability of naval protection.

A shipping lane can be declared open without immediately becoming commercially normal.

Tankers must be available. Crews must be willing to sail. Insurers must provide cover. Ports and pipelines must remain operational. Buyers must be confident that cargoes will arrive.

Oil supply depends on that entire chain—not simply on whether a ship can physically pass through a channel.

The threat moves west

The latest Houthi attacks matter because they move the danger towards the other side of the Arabian Peninsula.

Yanbu sits on Saudi Arabia’s Red Sea coast and is connected to oil-producing areas in the east by the kingdom’s East–West pipeline. That system allows Saudi oil to bypass the Strait of Hormuz and reach international markets through the Red Sea.

It is one of the principal pieces of infrastructure intended to provide resilience when the Persian Gulf route is threatened.

The Houthis have claimed responsibility for targeting an Aramco facility at Yanbu as well as sensitive sites in Riyadh. Saudi Arabia and Aramco had not confirmed the extent of any damage when this article was prepared.

However, the strategic message is already apparent.

Even as greater volumes begin moving through Hormuz, the alternative route designed to reduce dependence on Hormuz is itself being placed under pressure.

This does not yet amount to a confirmed new loss of supply. It does mean that traders, shipping companies and governments must now price a wider geographical risk into every barrel.

What it means for Australian motorists

Australia does not need to purchase every litre of petrol or diesel directly from Saudi Arabia for Saudi disruption to affect local prices.

Australian fuel prices are determined within an international market. If a major producer loses export capacity—or buyers merely fear that it might—competition increases for oil and refined fuel available elsewhere.

Asian refiners then pay more for crude. Importers pay more for petrol, diesel and jet fuel. Freight and insurance costs may also rise.

Those costs eventually reach Australian service stations, although not immediately or evenly.

Petrol prices can be obscured temporarily by local retail cycles. Diesel tends to provide a clearer indication of underlying supply pressure because it is heavily used by freight, mining, agriculture and industry.

The consequences therefore extend well beyond the amount displayed on a roadside price board.

More expensive diesel raises the cost of transporting food, building materials and consumer goods. It increases operating costs for farmers, contractors and regional businesses. Airlines and shipping operators face higher fuel bills. Governments pay more to operate essential fleets.

Fuel inflation moves through an economy long after the motorist has left the service station.

A proposed automatic cut to fuel tax

The deterioration in the international situation has produced a new Australian political proposal.

The federal Coalition has reportedly proposed a “fuel price shield” under which fuel excise would automatically be halved when the average closing price of Brent crude remains above US$100 a barrel for two consecutive weeks.

With the full excise presently about 53.7 cents a litre, halving it would remove approximately 27 cents a litre in tax. That represents roughly $16 on a 60-litre fill, assuming the reduction is passed through completely.

The proposal would also temporarily remove the heavy-vehicle road-user charge during a qualifying oil-price spike. That component matters because reducing the tax paid by motorists without addressing the charge applying to trucks would provide less protection against increases in freight and grocery prices.

Unlike an improvised temporary concession, the proposed system would establish a trigger in advance. It would tell motorists, businesses and the fuel industry when relief would begin rather than requiring another political decision during each crisis.

However, it would also raise difficult questions.

Brent crude is an important global benchmark, but it is not the only influence on Australian fuel prices. Australia is more directly exposed to Asian crude and refined-product markets, including the price of Tapis crude and regional petrol and diesel benchmarks.

It is therefore possible for Australian fuel costs to remain extremely high even when Brent falls below the proposed threshold.

A mechanism based solely on Brent could also switch tax relief on or off while local prices were moving in a different direction.

A tax reduction cannot create fuel

A reduction in excise can reduce the price paid by consumers. It cannot produce another tanker of diesel, repair a damaged pipeline or make a threatened shipping route safe.

That distinction should guide the national debate.

Fuel tax relief addresses affordability. Strategic reserves, diversified import sources, domestic refining capacity and secure shipping routes address availability.

Australia needs to consider both.

A tax reduction may be justified when an external shock imposes extraordinary costs on households and businesses. But it transfers part of that cost to the federal budget. The previous temporary reduction cost several billion dollars, demonstrating that even a modest per-litre concession becomes a substantial national expense.

There is also the question of whether the full saving reaches motorists.

Competition and consumer authorities must monitor wholesale and retail prices so that a tax reduction is not absorbed elsewhere in the supply chain. Retailers should not be blamed for international costs beyond their control, but neither should a public subsidy disappear into unexplained margins.

The Albanese Government has resisted immediately restoring the earlier excise reduction, arguing that it should not redesign policy in response to daily movements in oil prices. It has instead emphasised other cost-of-living measures and efforts to secure additional fuel supplies.

Energy Minister Chris Bowen is expected to visit Saudi Arabia for discussions about energy security and supply. The timing has become particularly significant now that Saudi energy infrastructure and the Red Sea export system are themselves under threat.

Relief today or resilience tomorrow

The proposed fuel-tax shield gives the Opposition a clear response to rising bowser prices. It also places pressure on the Government to explain what conditions, if any, would justify renewed excise relief.

But neither side should present a tax change as a solution to Australia’s underlying fuel insecurity.

Excise relief can soften the financial blow. It cannot remove Australia’s dependence on imported petroleum, expand domestic reserves overnight or restore normal passage through contested waterways.

The deeper policy question is whether Australia should continue responding to each fuel emergency as an unexpected event—or accept that interruptions to global energy trade have become a recurring national risk.

The Times View

The latest development is not simply another attack in an already crowded regional war.

The Strait of Hormuz remains impaired, but some shipping is returning. Now the Saudi route intended to bypass that danger is also being targeted.

The threat is moving through the system.

A temporary reduction in fuel tax may provide legitimate relief to Australian households and businesses, particularly if international prices remain above an agreed threshold. But it would treat the cost of the crisis rather than its cause.

Australia needs immediate protection from excessive fuel prices and a longer-term plan for maintaining supply.

A resilient country must be able to do both.
