Hands off our gas: WA pushes back against national reservation plan - WAtoday

Western Australia has resisted a national gas reservation scheme that would require producers to set aside a portion of output for domestic use. The state argues the policy would hurt investment and exports, and that its gas market is already functioning without such intervention.

Where this fits

This is a reliability and sovereignty story. Australia's eastern grid is being built on the assumption that gas will firm renewable output for the next decade or more. Yet WA, which holds a third of Australia's gas reserves, is rejecting the policy tool that would secure domestic supply. The choice reflects a deeper problem: Australia is building a renewables-heavy grid that depends on gas firming, while allowing market forces and export economics to determine whether that gas stays home. It is the inverse of energy security.

What it means

If WA gas is locked into export contracts, the eastern states face a choice between paying spot prices for dwindling domestic supply or accelerating their switch to a different firming source. That source is not renewables. It is either more gas (imported, expensively), imported batteries and inverters from China (a supply-chain risk in a strategic contest), or firm low-carbon generation, meaning nuclear, which is banned. The reservation push was crude policy, but it aimed at a real problem: a grid that cannot run without gas, a gas market that does not care whether it runs Australia's hospitals or Tokyo's factories, and no plan B.
