The Australian Energy Regulator (AER) has published the approved annual tariff variation proposal for network tariffs in 2026–27 for Jemena Gas Networks (JGN).
This follows an assessment by the AER of JGN’s tariff variations and proposed drivers to ensure they are consistent with its 2025–30 Access Arrangement.
JGN’s proposed increases to its gas network tariffs in 2026–27 are driven by recoverable costs for unaccounted for gas being higher than forecast, inflation and the real price path set in its 2025–30 Access Arrangement. The proposed tariffs also take into account tariff rebalancing.
Our Statement of Reasons provides a summary of the changes in network tariffs and pricing movements.
These network tariffs will be incorporated into retail gas prices from 1 July 2026 to 30 June 2027. Retailers ultimately determine how these underlying network tariffs are reflected in the retail prices offered to customers. The AER acknowledges that gas bills are a concern to many households and businesses. We encourage consumers to use the AER’s Energy Made Easy website, our free and independent price comparison tool, to find the best offer to suit their needs.
