Cyclone and Labor Disputes Knock Australia's Top LNG Plants Offline as Hormuz Cuts Qatari Supply
Simultaneous outages at Gorgon, North West Shelf and Ichthys since March 2026 have deepened the global LNG squeeze from the Middle East conflict.
JKM, the Asian spot LNG benchmark, stood at $27.51/MMBtu on Monday (2026-09-21) — more than double its level before the US-Iran war began, according to Commonwealth Bank of Australia analysis published on Tuesday (2026-09-08). Two overlapping supply shocks drove the move: the Strait of Hormuz disruption stripping Qatari cargoes from the market, and a succession of outages at Australia's biggest export terminals.7
The Hormuz strait carries around a fifth of global LNG supply. Its disruption has removed Qatari volumes that Asian buyers had long treated as reliable baseload supply, forcing them toward expensive spot cover from the Atlantic basin and the Pacific.7,1 That search ran into trouble when a tropical cyclone struck Western Australia on Thursday (2026-03-26).
Chevron's Gorgon and Wheatstone terminals were both disrupted. Santos reported a concurrent shutdown at its Barossa gas field, which feeds the Darwin LNG terminal.2 Three of Australia's major export facilities offline at the same moment. Australia is the world's second-largest LNG exporter, and the concentration made the supply loss hard to absorb in the short term.5,8
Montel reported the cyclone had temporarily halted production at the country's largest export sites. Buyers with contracts at affected plants faced force majeure, requiring spot cover at exactly the moment when the market had least to offer.1
The cyclone damage was still being worked through in May when Woodside's maintenance workforce walked out. Contractor UGL employees launched protected strike action at Woodside's North West Shelf and Pluto LNG facilities on Wednesday (2026-05-20), after pay negotiations collapsed.3 Two more major export terminals on the disruption list, both feeding volumes into an undersupplied Asian market.
Inpex's Ichthys facility, Japan's most significant LNG investment in Australia, then faced its own labor dispute. More than 430 members of the Offshore Alliance, AWU, and ETU threatened industrial action over pay and working conditions.6,4 A confrontation was initially averted on Tuesday (2026-05-26) after the union reported progress in talks with Inpex.4 But the reprieve did not last. A weeks-long strike materialized at Ichthys and ran until Inpex and the unions reached a final agreement on Wednesday (2026-06-17), bringing the workforce back.6
Commonwealth Bank's September 8 analysis noted that despite all of it, JKM had not revisited the extremes seen after Russia invaded Ukraine in 2022. LNG supply outside the Hormuz zone had expanded enough to absorb some displaced demand, preventing a full disorderly price spike.7
Australia's domestic market broadly reflects that relative stability. Wallumbilla hub gas traded at A$10.40/GJ as of Sunday (2026-09-20), and South Australia spot power cleared at A$40.01/MWh the same evening. Neither reading signals acute domestic shortage.7
ICE Brent crude front-month sat at $101.65/bbl as of Monday (2026-09-21), with Dubai crude at $116.35/bbl. The Dubai premium over Brent keeps the Middle East conflict embedded in crude grades flowing into Asian refineries. If the Hormuz situation deteriorates further, that premium feeds back into oil-linked LNG term contracts, adding a secondary pricing channel on top of already elevated spot JKM.7,1
The Australian market enters southern hemisphere spring with the acute labor disputes resolved. The Ichthys agreement holds, the Woodside NW Shelf situation has seen no reported escalation, and the Gorgon and Wheatstone shutdowns were described as temporary from the start. But the structural gap left by Hormuz-related Qatari losses has not narrowed. Another simultaneous hit across multiple Australian facilities, during a period of already constrained global supply, would stress the expanded supply base that Commonwealth Bank said has so far contained the damage.7,1
