Australian Gas Networks Limited, previously known as Envestra Limited, is an Australian energy firm that manages natural gas transmission pipelines and distribution networks in South Australia, Victoria, Queensland, New South Wales, and the Northern Territory. The company holds ownership of distribution infrastructure in major metropolitan and regional centers such as Adelaide, Brisbane, Melbourne, Rockhampton, Albury, Alice Springs, Bundaberg, and Whyalla. The operation and maintenance of these assets are contracted out to the APA Group.
The South Australian government's natural gas monopoly, SAGASCO, was acquired by Boral in October 1993. Subsequently, Boral combined SAGASCO’s distribution network with its Queensland operations to establish Envestra, which was then listed publicly in early 1997. In March 1999, Envestra broadened its reach by purchasing a segment of the former Gas and Fuel Corporation's distribution network in Victoria, which was subsequently renamed Envestra (Vic).
In 2013, APA Group put forward a proposal for an all-share merger with Envestra. By September 2014, all shares of Envestra were acquired by Hong Kong-based Cheung Kong Group, including APA’s 33.4% holding; despite this, APA continued to manage asset operations until 2027. The company adopted the name Australian Gas Networks Limited in October 2014.
In June 2025, the ACCC commenced legal proceedings against Australian Gas Networks concerning alleged greenwashing related to its advertising of renewable gas initiatives.
