Australian households and businesses on the east coast can expect stable gas prices through the final quarter of 2026, despite ongoing global energy market volatility. This reassurance comes from the Australian Competition and Consumer Commission (ACCC), which released its latest Gas Inquiry report on July 9, 2026. The report forecasts a healthy surplus of gas for the October to December period, though it flags potential supply challenges for the middle of 2027 without further investment.

East Coast Supply Outlook: Q4 2026 Stability

The ACCC’s report indicates that the east coast gas market is projected to be well supplied in the fourth quarter of 2026. This positive outlook includes a forecast surplus of 13 Petajoules (PJ) even under the scenario where Liquefied Natural Gas (LNG) producers export all their uncontracted gas. This represents the highest predicted fourth-quarter surplus since 2023, offering a degree of confidence for consumers heading into the warmer months.

Crucially, the report notes that recent surges in global energy prices, largely attributed to the Middle East conflict, have not yet had a material impact on domestic gas prices. This stands in stark contrast to the market conditions of 2022, when international conflicts significantly contributed to elevated gas prices across Australia’s east coast.

“Our analysis indicates the east coast gas market is expected to be well supplied in late 2026 and early 2027, although supply-demand conditions are likely to tighten in winter 2027, particularly in the southern states,” said ACCC Commissioner Anna Brakey.

Spot prices for gas are currently tracking below their 2025 averages, reflecting a period of stable demand and supply, aided by a relatively warm early winter period (April-June) that reduced heating requirements. Contracts agreed in the first quarter of 2026 for 2027 supply were also observed to be lower than the preceding quarter, generally aligning with pre-conflict levels.

2027 Winter: A Potential Tight Spot

While the near-term outlook is favourable, the ACCC report issues a clear warning regarding the second and third quarters of 2027. There is a risk of gas shortfalls during these peak winter months if LNG producers choose to export all their uncontracted gas volumes. This could lead to tighter supply-demand conditions, particularly impacting southern states such as Victoria, New South Wales, South Australia, and Tasmania, which traditionally rely on gas from Queensland and storage facilities to meet winter demand.

To mitigate these future risks, the ACCC stresses the necessity of further investment in gas production. The report highlights that increasing supply will largely depend on the Queensland LNG producers and their associates, who collectively control 84% of Australia’s commercially viable gas resources.

Broader Energy Market Context

The stability in gas prices for the latter half of 2026 provides some relief for consumers, particularly as other energy costs continue to evolve. For instance, recent Default Market Offer (DMO) and Victorian Default Offer (VDO) determinations for electricity, effective July 1, 2026, saw varied impacts across states. Most households in New South Wales and South East Queensland are experiencing reductions in their benchmark electricity prices, while South Australia saw a modest increase for flat-rate customers.

These electricity price movements, alongside gas market stability, underscore the complex interplay of factors influencing Australian energy bills. The ACCC’s findings reinforce the critical role of domestic supply and storage in insulating Australian consumers from global price shocks, even as the transition to a renewable energy grid continues to reshape wholesale electricity dynamics.

The ACCC’s latest report provides valuable transparency on the gas market’s near-term trajectory. For consumers and businesses, this stability offers a window to review energy contracts and consider long-term strategies. While wholesale gas prices are currently stable, the warning for 2027 highlights the ongoing need for robust energy planning and investment in new supply to meet future demand. This long-term view is essential for maintaining energy security and affordability in Australia’s evolving energy landscape.
