The ERA is responsible for regulating third-party access to gas pipelines in Western Australia.
There are currently three full regulated pipelines in Western Australia:
- Dampier to Bunbury Natural Gas Pipeline
- Goldfields Gas Pipeline
- Mid-West and South-West Gas Distribution System.
There is also one lightly regulated pipeline, the Kalgoorlie to Kambalda Pipeline.
The ERA also has a role enforcing and monitoring compliance with the non-scheme gas pipeline information disclosure and arbitration framework in Western Australia. This scheme covers pipelines that are not subject to broader regulation.
