Tropical Cyclone Narelle strengthened to category 4 intensity with winds of 165 kilometres per hour, forcing a cascade of production shutdowns across Australia's energy sector that will reverberate through global markets in the coming weeks.
On Thursday, the offshore gas platforms feeding Woodside Energy's North West Shelf export plant in Western Australia were shut due to the severe cyclone, while Chevron halted one of the three production units at its Gorgon plant as well as a platform feeding its Wheatstone facility. Together, these three plants supply about 8% of the world's liquefied natural gas. The combined annual capacity is staggering: the Gorgon plant can pump out more than 15 million metric tonnes of gas yearly, while Wheatstone at full capacity produces almost nine million metric tonnes.
The timing could hardly be worse. Global LNG markets were already under acute pressure before Narelle struck. Qatar, the world's second-largest LNG producer, has seen exports plunge as fuel tankers steer clear of the Strait of Hormuz following Middle East military escalation. LNG prices in some parts of Asia have more than doubled. For energy-importing nations across the Indo-Pacific, the loss of Australian supply creates a compounding supply shock.
Japan sources about 40 percent of its LNG from Australia, making these disruptions directly consequential for the region's largest economy. South Korea and China face similar dependencies. When Australian gas goes offline, Asian factories and power stations ultimately feel the pressure.
The broader vulnerability exposed by this event deserves scrutiny. Australia's major LNG operations cluster along Western Australia's cyclone-prone coast; Chevron and Woodside together account for more than 15 percent of international natural gas exports. A single weather system capable of threatening multiple critical facilities simultaneously raises uncomfortable questions about infrastructure resilience and concentration risk.
Industry analysts acknowledge the precarious timing. One gas sector analyst warned that the cyclone had come at the "worst possible moment", with even minor output reductions capable of triggering global market reactions.
The companies involved have pledged to restore operations once conditions allow. Chevron said in a statement it is "working to restore production" and will "resume full production at both facilities once it is safe to do so". Woodside indicated it would update markets in line with continuous disclosure obligations should material impacts occur.
For Australia, the situation highlights a sobering reality. Our energy sector, central to national prosperity and regional stability, operates within weather systems beyond our control and geopolitical tensions beyond our influence. The cyclone itself was a natural occurrence; the vulnerability was constructed by design choices made years ago.
