Our gas network
We own and operate one of three Victorian gas networks. Our 12,800 kilometres of gas mains and infrastructure covers an area of more than 60,000 square kilometres across central and western Victoria. This huge network delivers gas to approximately 824,000 homes and businesses.
Gas is an important part of the energy mix in Victoria and Victorians rely on gas more than any other state. Around four out of five Victorian homes are connected to gas, and the gas networks currently provide more energy than electricity networks.

The Gas Access Arrangement Review (GAAR)
The Australian Energy Regulator (AER) is responsible for regulating Australian gas distribution, which falls under a national framework.
Every five years, gas distributors across Victoria must submit a draft plan to the AER for the next five-year regulatory period. This plan outlines the services we will offer customers, the costs to deliver those services, and the plan for how we will use money collected via the distribution charge on customers’ bills. This process is known as the Gas Access Arrangement Review (GAAR).
Our current regulatory period expires on 30 June 2028. Read our current Gas Access Arrangement (2024 - 2028):
- Part A – Access Arrangement
- Part B – Reference Tariffs and Reference Tariffs Policy
- Part C - Terms and Conditions
We engaged extensively with customers and other stakeholders prior to submission to understand their needs and expectations of our network, and ensure they are reflected in our plan.
AER published its final decision on our access arrangements in June 2023.
The Gas Access Arrangement Review (GAAR) - Variation Proposal
On 30 September 2024, we submitted a proposal to the AER to vary our approved 2023–28 access arrangement. This was to respond to the Victorian Government’s policy decisions to restrict new gas connections. In January 2025, the AER made its draft decision not to accept our variation proposal. After careful consideration, on 14 March 2025 we wrote to the AER accepting the draft decision, acknowledging the AER's preference to defer these matters to the next full price review. The AER made its final decision on the variation proposal on 14 May 2025, consistent with the draft decision.
