Transmission and Distribution of Gas in Australia

Historically, distribution and retailing of gas was conducted by one company within each State, and gas customers had no choice of supplier. However, in recent years, these activities have been separated so that energy companies may now distribute gas on behalf of more than one retailer and can compete for customers in other States and Territories.

The different elements of the supply chain which delivers natural gas to Australian consumers are detailed in the following diagram.

Details of the current operators; including retailers in the WA Gas Market can be found at the Government of Western Australia – Office of Energy Website .
