Highlights

  • Woodside Energy faces growing debate over Western Australia’s domestic gas supply conditions as government policy changes are considered.
  • WA industrial customers have raised concerns about future gas availability and pricing pressures.
  • AEMO forecasts WA domestic gas demand growth of 2.2% annually to 2033 while supply declines around 0.9%.

Woodside Energy Group Limited (ASX:WDS) is facing increased scrutiny over Western Australia’s domestic gas supply outlook as industrial customers raise concerns about future availability and pricing. The debate comes as governments consider the design of a national domestic gas reservation scheme and assess how it will interact with WA’s existing policy framework.

Why it matters

Gas remains a key input for Western Australia’s mining, minerals processing and manufacturing industries, while also supporting electricity supply as coal-fired generation declines.

The discussion around domestic gas availability has implications beyond individual market participants, as it could influence energy policy, pricing structures and future investment decisions.

For Woodside investors, the outcome may affect the company’s operating flexibility, regulatory environment and relationship with domestic customers in its home market.

What happened

Industrial gas users and WA customers have raised concerns regarding domestic gas supply conditions and pricing, increasing focus on how much gas is allocated to local users compared with export markets.

The debate has intensified as the federal government considers a proposed national Domestic Gas Reservation Scheme and its interaction with Western Australia’s existing domestic gas policy.

Woodside remains one of the largest gas producers in the region through assets including the North West Shelf, Pluto LNG and the Scarborough development.

WA policy and proposed federal scheme

Western Australia has operated a domestic gas reservation policy since 2006, requiring LNG projects to reserve the equivalent of 15% of production for the domestic market.

Separately, the proposed Commonwealth Domestic Gas Reservation Scheme is expected to commence from 1 July 2027 and would require LNG exporters to supply 20% of exported volumes domestically, subject to contract arrangements.

The draft scheme was released for consultation on 27 May 2026, with submissions closing on 30 June 2026.

A key issue remains how the federal framework will interact with WA’s existing 15% reservation policy.

The numbers and market outlook

The Australian Energy Market Operator forecasts WA domestic gas demand to increase by approximately 2.2% annually through to 2033, while supply is expected to decline by around 0.9% annually.

This could result in a supply shortfall exceeding 100 terajoules per day from 2031, representing more than 10% of forecast demand.

Woodside states it has supplied more than 3,900 petajoules of domestic gas to Western Australia since 1984, equivalent to approximately 37% of its LNG export volumes over 42 years.

A 2024 parliamentary review found that around 8% of total LNG volumes reached domestic users, highlighting differences between reservation requirements and actual domestic supply volumes.

Strategic significance

The debate reflects a structural challenge for Woodside and other LNG producers: domestic gas supply and LNG exports represent different commercial outcomes.

Reservation requirements can influence how producers allocate gas between local customers and export markets. The final structure of the Commonwealth scheme could affect future project economics, export flexibility and domestic supply commitments.

The policy outcome may also influence future approvals and negotiations for energy projects across Western Australia.

Opportunities

A tighter domestic gas market could create opportunities for Woodside if demand increases and customers seek long-term supply agreements.

As existing gas fields decline and energy systems transition, producers with large-scale infrastructure may have opportunities to provide additional domestic supply.

The Scarborough project represents a potential source of future LNG volumes, with Woodside reporting the project was more than 96% complete and targeting first LNG production in the fourth quarter of 2026.

The company may also benefit from increasing demand for reliable energy supply while maintaining export exposure.

Woodside’s position, risks and counterarguments

Woodside states that it is a significant supplier of domestic gas in Western Australia and continues to meet obligations under the state’s domestic gas policy.

The company has argued that investment certainty is required to maintain future supply availability and that market pricing reflects supply-demand conditions.

Critics argue that producers may prioritise higher-value export markets over domestic customers.

For shareholders, risks include potential changes to reservation requirements, reduced export flexibility, regulatory uncertainty and reputational pressure linked to domestic supply discussions.

What to monitor next

Investors will monitor the final design of the Commonwealth Domestic Gas Reservation Scheme and how it applies to Western Australia’s existing policy.

Other areas include Scarborough project progress, domestic gas commitments, WA government policy developments, AEMO supply forecasts and Woodside’s upcoming financial updates.

Future commentary from regulators and market authorities will also provide insight into supply conditions, pricing trends and potential impacts on LNG producers.

A balanced view

Woodside’s domestic gas debate reflects a broader challenge facing Western Australia’s energy market. The state faces potential supply constraints, while producers balance domestic obligations with export opportunities.

The key disagreement centres on whether current market conditions reflect supply scarcity or insufficient domestic allocation.

The final policy framework, future supply developments and project execution will determine how the balance between domestic demand and export markets evolves.

For Woodside investors, the issue remains a regulatory and strategic consideration that could influence future operating conditions.
