The legislation, introduced to parliament last week, would require Australia's largest liquefied natural gas (LNG) exporters to reserve up to 20 per cent of their annual export volumes for local customers from 2028. The policy is designed to inject a modest oversupply into the domestic market, lowering heating, power and manufacturing costs for households and industry.
Existing long-term contracts signed on or before December 22, 2025 would be grandfathered and exempt from the scheme. However, the final bill explicitly states that contracts renewed, extended or rolled over after that date will lose that protection, even if extension options were part of the original terms.
Korea Gas Corporation (KOGAS), a major investor in the Santos-led Gladstone LNG terminal, said in its submission that protections should extend to the "entire duration" of the foundation supply purchase agreement, including automatic extension periods. Japan's INPEX, which operates the Ichthys LNG project in the Northern Territory, expressed "significant concern", arguing that capturing renewed contracts fails to protect historical investment decisions.
Resources Minister Madeleine King said the government had been clear that contracts entered into before December 22 would be grandfathered. "Any decision to extend an existing contract is a new commercial decision, made with full knowledge of the domestic gas reservation scheme," she said. "These decisions are therefore not covered by the transitional protections designed to honour existing commercial arrangements."
Local manufacturing firms have welcomed the move. Manufacturing Australia chief executive Ben Eade urged parliament to pass the bill, saying it would deliver a better functioning domestic gas market and reduce exposure to international price volatility.
Energy authorities have warned that Victoria and New South Wales could face gas shortfalls by the end of the decade as production from ageing Bass Strait fields declines. However, some analysts caution the rules may deliver little immediate benefit. Rick Wilkinson, chief executive of consultancy EnergyQuest, said: "There is no surplus gas washing around the system to reserve." He noted that Asian LNG buyers, who are also joint-venture investors in local infrastructure, feel entitled to exercise contract extension provisions.
