On 1 November 2024, the AER published the final gas ring-fencing decision guide.

The guide aims to assist gas pipeline service operators to better understand their ring-fencing obligations, and, where relevant, how to apply for exemptions from certain obligations.

It also outlines additional context and information about the AER’s processes and functions, including providing clarification on the requirements for applications or notifications to the AER on ring‑fencing matters.
