Australian Gas Networks Limited, formerly Envestra Limited, is an Australian energy company that operates natural gas transmission pipelines and distribution networks in South Australia, Victoria, Queensland, New South Wales, and the Northern Territory.
The company owns distribution systems in a number of towns and metropolitan areas including Adelaide, Brisbane, Melbourne, Rockhampton, Albury, Alice Springs, Bundaberg and Whyalla.
In October 1993, Boral acquired from the South Australian government SAGASCO, its vertically integrated natural gas monopoly.
Boral combined SAGASCO's distribution network with businesses it owned in Queensland to form Envestra, which was floated in early 1997.
