To supplement the voluntary gas supply hub located at Wallumbilla, the Moomba hub was established from 1 June 2016 to facilitate trade on the Moomba to Adelaide Pipeline (MAP) and Moomba to Sydney Pipeline (MSP). A spread product also allows for trading between the Wallumbilla and Moomba markets on the SWQP (representing the price differential between the two hubs at the MSP and WAL trading locations).
This figure is a summary of monthly on-market and off-market trading activity at the Wallumbilla hub. Off-market trades proceed under bilateral agreements and are excluded from AEMO’s netting and matching process. They are registered as a separate product and are not included in AEMO’s reference price calculations for the hub (as they do not reflect trades through the open exchange). This figure provides a monthly comparison of on-market and off-market trading by trade numbers and total volumes.
