Australia’s heavy reliance on imported fuels has emerged as a major economic vulnerability after the 2026 geopolitical conflict involving the US-Israel bloc and Iran triggered one of the largest global energy supply shocks in recent years, according to the Institute for Energy Economics and Financial Analysis (IEEFA). The report warns that reducing dependence on imported oil through transport electrification has become essential for long-term energy security and inflation control.
Between February 27 and March 9, 2026, global crude oil prices surged 51 percent, briefly approaching US$120 per barrel, while liquefied natural gas (LNG) prices jumped 77 percent. The market disruption intensified as around 60 fully loaded crude oil tankers were stranded in the Persian Gulf, with each vessel carrying up to 2 million barrels of oil—equivalent to two days of Australia’s total national oil consumption per tanker.
The crisis deepened after a direct strike on Qatar’s Ras Laffan gas complex, eliminating 19 percent of global LNG output compared with the previous year. The damaged 12.8 million tonnes of LNG production capacity is expected to take 3 to 5 years to restore fully, while mine clearance operations in the Strait of Hormuz are projected to require at least 6 months following the June 19, 2026 ceasefire.
IEEFA says Australia’s energy security has weakened significantly over the past 25 years due to rising dependence on imported petroleum products. The country now imports 90 percent of its diesel, 80 percent of its jet fuel, and 68 percent of its petrol, leaving transport, aviation and logistics sectors highly exposed to international fuel price volatility.
Fuel demand has also risen sharply. Since 2000, diesel consumption has increased by 2.5 times, while jet fuel demand has expanded by 1.8 times. Australia has consequently become the world’s largest net importer of seaborne diesel, accounting for 10.1 percent of global diesel trade. It is also the third-largest importer of seaborne jet fuel with an 8.3 percent share and petrol with a 6.7 percent share.
The report argues that oil price volatility has become a structural source of inflation. Since 2000, global oil prices have risen at an average annual rate of 8.9 percent, compared with 6.9 percent for crude oil benchmarks and 2.8 percent for consumer price index (CPI) inflation.
Higher fuel prices directly contributed 1 percentage point to Australia’s CPI in March 2026. Beyond direct fuel costs, oil represents 2 percent to 2.5 percent of total business input costs, increasing expenses across transport, manufacturing, logistics and service industries while also raising inflation expectations and the risk of prolonged wage-price pressures.
According to IEEFA, Australia has exceeded the Reserve Bank of Australia’s (RBA) 2 percent to 3 percent inflation target on six occasions this century, with oil price shocks acting as the primary trigger each time. In May 2026, the RBA responded by raising interest rates by 0.25 percent, although the report argues that monetary policy cannot resolve supply-driven energy shortages because higher interest rates cannot increase global oil production, repair damaged infrastructure or reduce international commodity prices.
The report identifies transport electrification as the most effective long-term solution because the transport sector accounts for approximately 75 percent of Australia’s total oil consumption. Under projected transition pathways, road transport oil demand could decline by more than 50 percent by 2040 and approach near-zero by 2050.
Electrifying Australia’s heavy freight fleet of more than 128,000 trucks could eliminate up to 10 billion litres of diesel consumption annually. However, supporting this transition would require national electricity demand to increase by approximately 42 percent compared with current levels.
IEEFA estimates that achieving full transport electrification will require investment of approximately A$1.3 trillion by 2050. The funding would support electric vehicles, charging infrastructure, electricity grid expansion and broader energy system upgrades, making it one of the largest infrastructure transformations in Australia’s history.
The report also highlights policy challenges, noting that higher interest rates increase borrowing costs for renewable energy projects, electric vehicles and charging infrastructure. To balance inflation control with long-term energy security, IEEFA recommends complementary fiscal measures, including a temporary windfall tax on fossil fuel export profits and targeted Reserve Bank financing mechanisms to reduce borrowing costs for electrification projects.
According to IEEFA, the 2026 energy crisis demonstrates that oil price shocks are no longer temporary disruptions but a structural macroeconomic risk. With crude oil prices rising 51 percent, LNG prices increasing 77 percent, 60 oil tankers stranded, 19 percent of global LNG production disrupted, and Australia relying on imported fuel for 90 percent of diesel, 80 percent of jet fuel and 68 percent of petrol, the report concludes that accelerating transport electrification through A$1.3 trillion of investment and expanding electricity supply by 42 percent will be essential for improving energy security, reducing inflationary pressure and strengthening long-term economic resilience.
