Join the Market
The voluntary Wallumbilla Gas Supply Hub allows for a faster response, greater liquidity, and flexibility in trading gas.
It provides a centralised trading, settlement and clearing facility through an online portal and enables generators, users, producers and retailers to manage their daily and future gas requirements.
Features of the hub include:
- AEMO uses best practice from around the world to provide a new trading environment.
- The 1TJ contract size allows for trading flexibility.
- It provides another trading mechanism for participants already operating in the Short Term Trading Market.
AEMO will offer spot and forward-dated products participants to trade at the hub. The spot transactions include a core ‘day-ahead’ product and a ‘balance-of-day’. The ‘balance-of-day’ product enables parties to adjust their portfolio closer to real-time and to manage imbalances within the gas day.
Pipeline capacity will also be offered as a trading opportunity which allows more efficient use of pipelines and helps create more opportunities to trade gas.
For more detail see the gas supply hub exchange agreement below and the Gas Supply Hub registration guide.
The exchange agreement outlines the terms and conditions that govern participation in the gas supply hub.
Each participant will accede to the membership agreement, under which it agrees to be bound by the rules and associated terms and conditions.
The Exchange Agreement was developed in close consultation with industry and government stakeholders via the Reference Group.
The Gas Trading Exchange Rules took effect on 1 January 2014. Version 4 of the Exchange Rules have an effective date of 28 May 2015

Capacity Trade Agreement Standard Terms (Shipper to Shipper)
AEMO has published standard terms and conditions that shippers may choose to adopt for capacity trades between them (bare transfers).
The standard terms and conditions have been developed in close consultation with industry.
Trading parties must use the form of Contract Document (schedule 2) to record the terms of each capacity trade and any agreed variations or additions to the standard terms.
Shippers who expect to trade with each other more than once may also wish to record any terms that will apply to all trades between those parties in a Master Capacity Trading Schedule (schedule 1).
The Contract Document and Master Capacity Trading Schedule forms can be downloaded separately.
Note that these standard terms and conditions are not limited to trade at the Wallumbilla Gas Supply Hub and may be used for other (non GSH) pipelines.
