Gas Markets


Wholesale gas trading in Australia revolves around formal markets, centred on hubs and operated by market operators, and informal B2B markets for supply and transportation of gas from sources of supply to the gas hubs.

The Australian Energy Market Operator (source: operates the Retail and Wholesale Gas Markets in South-East Australia, and the Victorian Gas Declared Transmission System.

REMCo ( is the gas retail market operator responsible for the administration and development of the Western Australian gas retail market.

AEMO operates the Gas Short Term Trading Market (STTM), which is a wholesale market system designed to facilitate Short Term Gas trading driven by daily prices. The STTM currently operates in New South Wales, Queensland and South Australia.

In Victoria, a wholesale gas market involves trading around injections/withdrawals from the transmission system linking producers, major users and retailers.

Most of these gas markets are based on bilateral arrangements between producers, major users and retailers linked together through pipeline hubs connecting gas fields to gas consumers.

Participants in these markets must:

  • Identify gas supply or demand requirements
  • Procure supply of gas and transportation, through both formal and informal (B2B) market methods
  • Optimise contract and network topography for commercial benefit
  • Capture and settle complex trades.
