The voluntary Gas Supply Hub (GSH) allows for a faster response, and 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.
AEMO offers spot and forward-dated products for 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 is also offered as a trading opportunity, allowing more efficient use of pipelines and helping create more opportunities to trade gas.
The exchange agreement outlines the terms and conditions that govern participation in the gas supply hub. It was developed in close consultation with industry and government stakeholders, via the Reference Group.
Each participant will accede to the membership agreement, under which it agrees to be bound by the rules and associated terms and conditions.

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 GSH, and may be used for other (non-GSH) pipelines.
