About Us

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

The AGN gas distribution networks deliver gas to over 1.3 million homes and businesses in South Australia, Victoria, Queensland, New South Wales and the Northern Territory. We are one of Australia's largest natural gas distribution companies, with over 25,000 kilometres of distribution networks and 1,000 kilometres of transmission pipelines. AGN receives a portion of the Energy Retailer natural gas invoices to consumers, which covers the costs of transporting natural gas from the high pressure transmission pipelines to your street and home.

Where we operate

We operate natural gas networks 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. Each year, we invest around $250 million to maintain and grow our networks by 30,000 new customers each year.

Our History

Australian Gas Networks has its origins dating back some 150 years to the gas distribution networks of the former South Australian and Brisbane Gas Companies, and the Gas and Fuel Corporation of Victoria.

The South Australian and Brisbane Gas Companies (which started operating in the 1860s) were owned by Boral Limited. In 1997, Boral sold these distribution networks by creating Envestra Limited a public listed company. In 1999 Envestra acquired part of the former Gas and Fuel Corporation's distribution network in Victoria.

In 2014 the CK Group acquired the listed shares in Envestra Limited and changed the name to Australian Gas Networks which represents our business and supports our vision to be the leading gas distributor in Australia.
