Australian households and businesses could see greater stability in their gas bills, as the Federal Government prepares to introduce legislation next week to establish a national Domestic Gas Reservation Scheme. This landmark policy aims to mandate that liquefied natural gas (LNG) exporters reserve up to 20% of their total production for the domestic market, with the scheme set to take effect from July 1, 2027, and supply obligations commencing January 1, 2028.
The move comes in direct response to persistent concerns over East Coast gas supply and price volatility, a sentiment reinforced by the Australian Competition and Consumer Commission’s (ACCC) latest Gas Inquiry September 2026 interim report, released on October 8, 2026.
East Coast Supply Concerns Drive Policy Shift
The ACCC’s recent report projected a smaller-than-expected gas surplus for Australia’s east coast in the first quarter of 2027, ranging from 5-15 petajoules (PJ). This forecast marked a 9 PJ downgrade from the ACCC’s June projections, primarily due to anticipated falls in southern state gas production and increased export demand. The report highlighted that while supply is expected to meet demand in the near term, conditions are likely to tighten significantly over winter 2027, particularly in the southern states.
“It is encouraging to see gas users securing more gas at broadly stable long-term prices, which is important for business certainty,” ACCC Commissioner Anna Brakey said in relation to long-term contracts.
Despite this, the ACCC noted that average prices under long-term contracts for 2027 and 2028 supply remained relatively steady at around $12 to $13 per gigajoule (GJ) during the first half of 2026. However, the government’s scheme is designed to address potential future shortfalls and insulate domestic consumers from international price spikes.
How the Domestic Gas Reservation Scheme Will Work
The proposed Domestic Gas Reservation Bill 2026, which underwent public consultation ending September 24, 2026, aims to deliver Australia’s first national scheme of its kind.
Key details of the scheme include:
| Feature | Detail |
|---|---|
| Obligation | LNG exporters must reserve up to 20% of production for domestic use. |
| Commencement | Scheme takes effect July 1, 2027. |
| Supply Obligation | Domestic Supply Obligation (DSO) commences January 1, 2028. |
| Exemptions | No LNG exporter will receive a full exemption from the new rules. |
| Flexibility | Reservation volume to be reviewed annually, based on a rolling five-year demand forecast. |
| Administration | The Australian Energy Regulator (AER) will administer the new export licensing and compliance regimes. |
The government estimates the scheme could make up to 200 petajoules of additional gas available to Australian consumers each year, a volume intended to exceed AEMO’s forecast possible shortfalls of up to 140 petajoules.
Industry Concerns vs. Government Objectives
While the government asserts the scheme will put “downward pressure on domestic gas prices” and strengthen energy security, the proposal has faced opposition from gas producers. Industry bodies, including Australian Energy Producers (AEP), have voiced concerns that such requirements could weaken Australia’s reputation as a reliable LNG supplier to global markets and potentially deter investment in new gas supply.
Producers argue that diverting a fixed percentage of exports could create a structural oversupply in an already well-supplied domestic market, potentially undermining investment and reducing competition. However, the government maintains that a secure and affordable domestic gas supply is crucial for Australian households, businesses, and industry, particularly in the context of the broader energy transition.
This new legislation represents a significant intervention in Australia’s gas market, aiming to balance export commitments with domestic energy needs. The coming months will reveal how the final legislative package is received and its long-term impact on gas prices and investment across the East Coast.

The Broader Energy Context
The push for gas reservation also occurs amidst Australia’s accelerating transition to renewable energy. While gas continues to play a role as a transitional fuel, particularly for firming capacity, the long-term strategy involves reducing reliance on fossil fuels. Policies like the Domestic Gas Reservation Scheme are designed to manage the affordability and security of traditional energy sources during this transition, ensuring a stable supply as new renewable infrastructure comes online.
