Ichthys LNG Strike Settled as Japan Utilities Scramble for Replacement Cargoes
Australia's Ichthys LNG workers end strike after Inpex deal, but Japanese inventories remain 16% below year-ago levels amid Hormuz supply losses.
Trade unions at Inpex's Ichthys LNG project reached an agreement on pay and benefits with the Japanese energy company on Wednesday (2026-06-17), ending a weeks-long strike that had threatened to compound severe supply losses from the Strait of Hormuz disruption. More than 430 members of the Offshore Alliance, AWU, and ETU will return to work at the 9.3 million tons per annum facility in Australia's Northern Territory.6
The settlement removes one supply risk from a market already stretched thin by the closure of Qatar's Ras Laffan complex. Asian LNG prices stand 75% above pre-conflict levels from late February, when the war between the United States and Israel against Iran began. QatarEnergy estimates damage to Ras Laffan, the world's single largest LNG-producing facility, will cost roughly $20 billion per year in lost revenue and take up to five years to repair.5
Japan's utilities had been watching the Ichthys dispute closely. Their LNG inventories sat at 1.95 million tons as of May 24, down 15.9% from the same point in 2025 and 10.1% below the five-year average. Power companies have been unable to simply switch to coal to cover the shortfall. A policy shift intended to boost coal utilisation has provided only limited relief, with utilities limiting coal buying amid uncertainty over how long the Hormuz disruption will last.3,1
The industrial action at Ichthys escalated progressively before the resolution. Union members had voted to increase work stoppages from four hours to eight hours per day across all three sites starting June 11. That vote followed an initial round of limited industrial action that began in late May, when the Offshore Alliance notified Inpex of its intention to disrupt operations unless the wage dispute was resolved.4,5
That the strike ended before a full work suspension took hold matters for the physical market, but it does not restore balance. Japan's ten major power utilities have seen LNG stocks run 8-16% lower than year-ago levels for four consecutive weeks, averaging 12% below. Even with Ichthys back at full rates, those inventories need rebuilding before winter draws down begins.3
The dispute at Ichthys was not the only Australian labour action this season. Maintenance workers employed by contractor UGL launched protected strike action at Woodside Energy's North West Shelf and Pluto LNG facilities in mid-May after negotiations over a new enterprise agreement stalled. Woodside has not yet confirmed a resolution to that action.2
Supply-side noise from Australia has coincided with a structural shift in the country's LNG pipeline. Inpex struck a deal on May 20 to buy PetroChina's stake in the Browse project, Australia's largest undeveloped gas resource with 14 trillion cubic feet of gas. Woodside, which operates Browse and holds a 30.6% share, is evaluating whether to intervene and match Inpex's bid. Development could cost $35 billion.3
JKM Asian LNG prices continue to trade at $23.76/MMBtu, reflecting a market that has priced in sustained supply losses. The Australian strikes were never going to move that needle much on their own, but they intersected with the Ras Laffan outage at the worst possible moment for Asian buyers.5
The resolution at Ichthys means one variable is removed from the supply equation. The bigger question remains whether Japanese utilities can rebuild inventories through the northern hemisphere summer without driving spot prices even higher. Their stocks are already 10% below the five-year average, and coal substitution is hitting its limits.3,1
What bears watching now is whether the Woodside dispute at North West Shelf and Pluto follows the Ichthys pattern or drags on. Those facilities feed a different customer base, and any extended disruption there would tighten the Atlantic-facing market even as Asian buyers absorb the Ichthys restart. The next Japanese utility stock report will show whether the post-settlement cargoes are arriving fast enough to narrow the deficit before the seasonal build peaks.
