Australian Gas Network (AGN) is part of the Australian Gas Infrastructure Group (AGIG), which owns and operates gas transmission and distribution pipelines across Australia.

AGN is one of Australia's largest natural gas distribution companies. We own approximately 26,300 kilometers of natural gas distribution networks and 1,800 kilometers of natural gas pipelines, serving over 1.42 million household customers in South Australia, Victoria, Queensland, New South Wales and the Northern Territory.

We deliver gas safely and reliably to Australian homes and businesses every year.

We own, operate and maintain these pipelines and infrastructure assets, and customers will engage with an energy retailer to transport natural gas through our networks.

We are a key part of Australia’s energy network, playing a vital role in the supply of natural gas to households, small businesses and industry partners across the country.

Where we operate 

We operate natural gas distribution in population centres in South Australia (covering the greater Adelaide region), Victoria (Melbourne CBD to the north and north-east, and south east of Frankston and Cranbourne to regional towns as far as Bairnsdale), Queensland (north of the Brisbane River), and regional centres including Albury, Wagga Wagga and Alice Springs. 

As a gas distribution company, we do not sell gas directly to customers. 

AGN transports gas from larger transmission pipelines into smaller distribution pipes that connect directly to households and businesses. While we own and maintain the distribution network, customers purchase gas from energy retailers, who also manage billing.

Renewable Gas  

We’re helping drive the transition to cleaner energy by delivering reliable natural gas today while building renewable gas solutions for tomorrow.

Through our Hydrogen Park projects, both operating and under development, we are already blending up to 10% renewable hydrogen by volume into the gas network, with plans to reach 20% and beyond. This demonstrates how renewable gas can be delivered safely and reliably through existing infrastructure, giving households and businesses an early experience of hydrogen in their energy mix.

As these projects expand, renewable gas has the potential to play a critical role in decarbonising hard-to-abate sectors where alternatives to gas are limited, including industrial heat, chemical feedstocks, and heavy mobility. By making use of our existing networks, renewable gases such as hydrogen and biomethane can provide a scalable pathway to reduce emissions while supporting energy security.

In some projects, customers use the blended gas directly. In others, the associated environmental benefits are allocated to commercial and industrial users through renewable gas certificates. This approach ensures that renewable gas development is recognised and rewarded, while continuing to supply reliable energy to all connected customers.
