Australia Considers 25% Gas Export Tax — Japan Should Not Treat This as Someone Else’s Problem

Australia is Japan’s largest supplier of liquefied natural gas. Any Australian government decision to impose export taxation on LNG — even at modest rates — has direct implications for the long-term contract pricing that underlies Japanese energy security planning.

The policy logic in Australia is straightforward: Australian consumers and industries are paying world prices for domestic gas while the resource is exported for profit. A resource rent tax recaptures some of that value for Australian public finances. The policy logic from Japan’s perspective is different: predictability in energy supply contracts is itself a form of economic value, and policy unpredictability imposes costs that don’t appear in the export tax rate.
