The government will introduce legislation this week to start a new domestic gas reservation policy. Shell Australia chair Cecile Wake said, "Fundamentally, it's a sledgehammer to crack a nut." The plan requires exporters to reserve gas from January 1, 2028, but many fear this heavy intervention could cause market failure.

The government is set to introduce legislation this week to parliament to implement its new domestic gas reservation policy to address supply shortfalls and bring down energy prices.

Cecile Wake, chair ​of Shell Australia, which exports gas from the Queensland Curtis LNG project, ​said that while she did not oppose the concept of a ⁠domestic gas reserve, there were major flaws in the current policy's design.

"Fundamentally, it's ​a sledgehammer to crack a nut. And it is an extraordinarily heavy-handed intervention into ​a market that is actually working well," she told a conference in Sydney.

The draft proposal requires energy exporters ​to reserve up to one-fifth of their production as determined by the energy regulator from January 1, ‌2028 ⁠to deliberately oversupply Australia's east-coast gas market by 110% of forecast demand.

The government has maintained that the producers "must supply" a certain percentage of their output to the local market, and not just offer it to any prospective buyers.

Wake said those measures ​would drive prices down ​too far and ⁠potentially "sow the seeds of tomorrow's market failure".

"It is such a blunt instrument. It is not talking about modest downward pressure on ​prices. The architecture, and that may well be the intention, ​but the ⁠way it would play out … is to drive prices below the long-run marginal cost of bringing new production out," she said.

Australia is one of the world's largest LNG ⁠exporters ​and ships more gas overseas than it consumes domestically.

But ​most of the country's large gas reserves are located in the northwest, far from the more populous ​southeast where demand is concentrated.
