APA Group is an Australian energy infrastructure company that owns and operates a portfolio of assets across all states and territories. The company was established in 2000, when it demerged from the Australian Gas Light Company and was listed on the Australian Securities Exchange. It is one of the largest natural gas infrastructure business in Australia, transporting around half of the country’s domestic gas supply. In addition to gas pipelines, APA has expanded into renewable energy, firming generation, and electricity transmission as part of the national transition towards net zero emissions by 2050. History In June 2000 AGL floated its gas transmission assets as the Australian Pipeline Trust, and listed it as a separate entity on the Australian Securities Exchange. The ASX code assigned to the securities was APA. During the next two decades, APA Group expanded its gas transmission network and began diversifying into electricity and renewable energy. The company acquired key assets including the Goldfields Gas Transmission and Parmelia pipelines in Western Australia, the Carpentaria Gas Pipeline in Queensland, and the Murraylink electricity interconnector.
