2026 Wholesale Gas Reserves Price Assumptions Report

The AER has published its third annual wholesale gas reserves price assumptions report, containing analysis of contracted and uncontracted reserves price assumptions submitted for calendar year 2025. The analysis identified a downward shift in 2025 contracted reserves price assumptions compared to the prior year, alongside a narrowing of the spread of uncontracted price distributions, which may indicate more consistent forward-view expectations on future gas prices at the time of reporting. The report follows implementation of gas market transparency reforms under the National Gas Amendment (Market Transparency) Rule 2022, which introduced reporting requirements for gas field owners. Data pre-dates the 2026 Middle East conflict so recent geopolitical effects on price assumptions are not reflected.
