The Albanese Government has announced a landmark domestic gas reservation scheme, requiring gas exporters to set aside 20 per cent of their production for the Australian market from 1 July 2027. This policy shift, confirmed this week, is designed to exert significant downward pressure on domestic gas prices, shield Australian households and industries from global price volatility, and bolster the nation’s energy security by mitigating potential supply shortfalls.

The announcement comes after years of advocacy from industry and consumer groups, particularly concerning the East Coast gas market, which has seen prices triple in the decade since liquefied natural gas (LNG) exports began. Historically, gas prices on Australia’s east coast have been notably higher, ranging between AUD $13 and $15 per gigajoule (GJ), compared to Western Australia’s regulated market, where prices typically sit between AUD $6.50 and $8.50 per GJ.

Addressing Price Volatility and Supply Concerns

Australia is a major global LNG exporter, yet its domestic market has often been exposed to international price surges. The absence of a formal domestic gas reservation policy, unlike many other gas-exporting nations, has left local consumers vulnerable. The new scheme aims to rectify this by ensuring a consistent, affordable supply of gas for local needs. Minister for Climate Change and Energy, Chris Bowen, emphasised the government’s commitment, stating, “We’ve been acting to shield Australians from global energy shocks by investing in reliable, sovereign renewables and keeping more of the gas we need onshore.”

“Our sensible, practical policies mean we will avoid gas shortfalls and will be able to protect consumers from global energy price spikes.”

The policy’s introduction follows warnings from the Australian Energy Market Operator (AEMO) about potential gas shortfalls on the East Coast by 2029, with additional supply needed by 2030. The declining output from traditional sources like the Gippsland Basin in Bass Strait has underscored the urgency of securing future supply.

Policy Mechanics: What 20% Reservation Means

Under the new framework, LNG exporters will be required to divert the equivalent of 20 per cent of their export volumes to the Australian domestic market. This obligation will primarily affect new export contracts entered into after 22 December 2025, with existing long-term contracts signed before this date being grandfathered (exempt) from the new requirements.

The Department of Climate Change, Energy, the Environment and Water (DCCEEW) stated the scheme will:

  • Put strong downward pressure on domestic gas prices.
  • Shield Australian industry from global price volatility.
  • Ensure Australia’s energy security by avoiding potential gas shortfalls.

Minister for Resources, Madeleine King, highlighted that the reservation also provides industry with the certainty needed for ongoing investment in Australia’s gas sector. This stability is crucial for energy-intensive industries, particularly in regions like North and North West Queensland, where access to reliable and competitively priced gas is essential for manufacturing and employment. Townsville Enterprise, a regional development body, lauded the announcement, noting its direct impact on keeping smelters, refineries, and manufacturers operational.

Impact on East Coast Gas Market

The primary beneficiaries of this policy are expected to be the East Coast states of Queensland, New South Wales, and Victoria, which have historically faced higher and more volatile gas prices compared to Western Australia. The Western Australian government has had a 15 per cent domestic gas reservation policy in place since 2006, although its effectiveness has been debated.

The increased domestic supply from LNG exporters is anticipated to create a modest oversupply of gas in eastern Australia, which is a key mechanism for driving down prices. The Institute for Energy Economics and Financial Analysis (IEEFA) noted the policy is “long-awaited” and expected to place some downward pressure on prices that have escalated significantly over the last decade.

While the policy’s full price impacts will not be felt until its commencement in July 2027, the announcement provides a clear signal to the market and offers a degree of future certainty for businesses and households. For consumers concerned about immediate costs, understanding broader energy efficiency measures remains vital.

Broader Context: Energy Transition and Affordability

The domestic gas reservation scheme forms a critical part of the government’s broader “Future Made in Australia” agenda, aiming to secure industrial capability and support the transition to an 82 per cent renewable energy grid by 2030. Gas is acknowledged as having an important transitional role, providing essential firming capacity for the grid when renewable generation is low.

However, the government also continues to push for greater energy efficiency and electrification to reduce overall reliance on gas. Households looking to reduce their energy bills in the interim can explore various upgrades.

The domestic gas reservation policy represents a significant intervention in Australia’s energy market, signalling a clear intent to prioritise national needs and stabilise energy costs for years to come. While its implementation is still over a year away, the policy’s announcement provides a tangible measure against future price shocks.
