Wallumbilla in Queensland is a major gas supply hub. As a pipeline interconnection point for the Surat-Bowen Basin, it links gas markets in Queensland, South Australia, New South Wales and Victoria. It services industrial gas customers, LNG export facilities and gas powered generators, making it a natural point of trade and an ideal location for a gas trading exchange.
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).
From 28 March 2017, the Wallumbilla hub was transitioned to a single product design. The WAL information in the figure is grouping the former South West Queensland Pipeline (SWQP), Roma to Brisbane Pipeline (RBP) and Queensland Gas Pipeline (QGP) trading locations under WAL. A separate in-pipe trading point at Wallumbilla was also introduced at SEQ in the transition. The trading activity at MAP and MSP has been grouped as MOO in the figure.
The information shown in this figure is the gas traded in the Wallumbilla and Moomba Gas Supply Hubs, displayed by the date of delivery of the traded commodity (as opposed to the date the trades occurred).
