Australia will submit final rules next week for a Domestic Gas Reservation plan
requiring LNG exporters to retain up to 20% of total output for the domestic
market to address expected east‑coast gas tightness toward the end of the
decade. The scheme is due to take effect on July 1, 2027. Major producers and
exporters warn the mandate could weaken Australia’s role as a reliable global
LNG supplier, sources involved in drafting the bill said.
