THE 90-DAY OBLIGATION
IEA member countries are required to hold petroleum stocks equivalent to 90 days of net imports. Australia has been in breach of this obligation continuously since 2012 — the only IEA member to fail the test for over a decade.
THE REFINING COLLAPSE
Australia had eight refineries in 2000; by 2021 only two remained — Geelong and Lytton. Domestic refining margins could not compete with megascale Singaporean and Korean refineries, so Australia became dependent on finished-product imports rather than crude.
THE 1973 ORIGIN
The strategic petroleum reserve concept was invented after the OPEC oil embargo of 1973-74, when Arab producers cut exports to nations supporting Israel in the Yom Kippur War. The IEA was founded in 1974 specifically to coordinate emergency stocks; the US Strategic Petroleum Reserve was authorized in 1975.
THE TICKETS WORKAROUND
Rather than building physical storage, Australia spent years buying 'oil tickets' — contractual rights to draw from US and Dutch reserves during emergencies. Critics called this an accounting trick: the oil sits 15,000 km away in Louisiana salt caverns, requiring weeks of tanker transit to reach an actual fuel crisis.
WHY HORMUZ MATTERS TO CANBERRA
Roughly 90% of Australia's refined fuel imports transit through or originate near maritime chokepoints — primarily Singapore, which itself depends on Persian Gulf crude. A Hormuz disruption ripples through Singaporean refineries within weeks, and Australia's tanker queue stretches halfway across the Indian Ocean.
THE QUIZ
Strategic reserves only work if they can be drawn down faster than the crisis unfolds. Most national reserves can release at rates of roughly 1-4 million barrels per day — meaningful for a 90-day shock, useless for an instant cutoff.
