The Australian Energy Regulator (AER) has published the approved annual tariff variation proposals for network tariffs in 2026–27 for Australian Gas Networks (Victoria and Albury) (AGN), AusNet Gas Services (AusNet) and Roma to Brisbane Pipeline (RBP).
This follows an assessment by the AER of AGN, AusNet and RBP’s tariff variations and proposed drivers to ensure they are consistent with their respective Access Arrangement determinations.
The proposed increases to these gas network tariffs in 2026–27 are driven by inflation and for AusNet and RBP the real price path set in their respective Access Arrangements. The proposed tariffs also take into account tariff rebalancing for AGN and AusNet.
Gas bills are made up of the wholesale costs, retail margins, and network charges. Our annual pricing review relates only to the network charges component of the bill.
Every year regulated gas distribution and transmission pipeline businesses submit a tariff variation notice to us that contains the network tariffs they propose to charge their customers to recover their revenues.
Our Statement of Reasons provides a summary of the changes in network tariffs and pricing movements for each of the networks.
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 on Victorian networks to use the Victorian Energy Compare website, and consumers in other jurisdictions to use the AER’s Energy Made Easy website, to find the best offer to suit their needs.
