The Australian Energy Regulator (AER) has published the approved annual tariff variation proposals for network charges in 2025–26 for gas network businesses from the Australian Capital Territory, South Australia, Victoria, Queensland and Northern Territory.
This follows an assessment by the AER of each of the tariff variations and proposed drivers to ensure they are consistent with each networks access arrangements.
All gas network providers proposed increases to gas network tariffs this year, driven by inflation, the real price path set in their respective determinations, the annual update to the regulated rate of return, and other adjustments.
Our Statement of Reasons for each network provides a summary of the changes in network charges and pricing movements.
These network charges will be incorporated into retail gas prices for the upcoming 2025–26 year. 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 deal to suit their needs.
This completes our assessment of annual tariff variations for gas network businesses as they will apply in the 2025–26 period.

BACKGROUND
Gas bills are made up of the wholesale costs, retail costs, 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.
