In this 3rd post on Australian diesel imports, the focus is on the dependency on Middle East oil as Israel and Iran have started to attack their oil refineries.

The problem started decades ago with peak oil in a dictatorship at 6,600 kb/d in the mid 1970s, under the Shah.
Sal Mercogliano in his Youtube Channel describes:

At the very end of the video: How could Iranians close the Strait of Hormuz?
Attack tankers with gun boats
Limpet mines attacks
Shore-based and ballistic missiles (similar to what Houthis do)
Launch unmanned surface vehicles
Mine the whole Strait – most dangerous
These are scenarios which may happen only at the very end, in a revenge and suicide action by a desperate regime in Tehran.

Around 0.5 million b/d transited the strait in 2022 from Saudi ports in the Persian Gulf to Saudi ports in the Red Sea.

So what does that mean for Australian diesel imports which come from these Asian countries?

As already shown in Fig 20 (South Korea) and Fig 24 (Japan) in the previous post, these countries depend on crude oil imports from the Middle East at 72% and 90% respectively. We look now at the other countries.

The panel at the bottom right shows oil refineries input dependent on imports at the rate of 7,235/(7,235+15,739)= 31.5%. The Middle East shares of these imports have been calculated with data from the Observatory of Economic Complexity https://oec.world/en
Let’s put all this information in one table and summarize:
Please note that some of the data are from previous years and may have changed by now. What the table suggests however is that around half of Australia’s diesel imports indirectly depend on Middle East oil.
How about Australia’s crude oil imports for the 2 last remaining refineries?

Except for occasional imports from the UAE, Australia’s crude imports are not dependent on the Middle East. Traditionally, imports come from neighbouring countries in South East Asia but these declined as crude production in this area peaked around 2001 and Australian refineries started to close down from 2013 onwards. This website followed the shutting down of refineries one by one and how this increased Australia’s oil vulnerability.

However, Malaysia, Vietnam and Brunei are themselves dependent on crude imports from the Middle East and may be reluctant to export crude to Australia in case of shortages or disruptions. In addition, Australia’s geographic remoteness is not advantageous in spot trading.
Media mis-informs
Australian media have dropped the ball on oil at least 10 years ago which created a deep-seated complacency among the public. The latest examples by the public broadcaster ABC:
Evan Lucas on the Business program on the day the Israel/Iran war started (13/6/25)
“…. the Strait of Hormuz, the reason that’s a massive concern for Europe….”
Half-truth, as if Australia were not impacted.
In the evening news on 14/6/25 it is mentioned that 20% of global oil passes through the Strait of Hormuz but not that 80% goes to Asia.
If ABC TV had bothered to use the simple search word “Hormuz oil flow” it would have immediately come across an earlier version of the above EIA article https://www.eia.gov/todayinenergy/detail.php?id=61002
Conclusion
The time to get away from oil was under John Howard 20 years ago when CNG for urban trucks and LNG for long distance trucks and rail freight could have been introduced as alternative transport fuel instead of exporting gas as LNG. The CO2 is in the atmosphere anyway.
Given the dangerous situation there are only limited options available:
(1) Give up perpetual growth strategies in capital cities
(2) Do not approve big projects with high consumption of diesel during construction
(3) Reduce immigration IMMEDIATELY because the more immigrants come here, the longer the lines at the filling stations and the faster the shelves in shopping centres will empty (remember the Wuhan virus in 2020?)
(4) Educate all politicians, advisors, consultants and journos on oil & energy
Update:
With data up to December 2025
