The Allgas Gas Network (previously known as the APT Allgas distribution system) is owned by Allgas Energy Pty Ltd (Allgas Energy) and operated by the APA Group. Allgas Energy is owned by GDI (EII) Pty Ltd which is a joint venture between Marubeni Corporation (40 per cent interest), SAS Trustee Corporation (40 per cent interest)) and the APA Group (20 per cent interest).
The previous owner and service provider of the Allgas gas distribution system was APT Allgas Energy Pty Limited (a wholly owned subsidiary of the APA Group). In December 2011, APA sold the distribution system to the GDI (EII) joint venture.
The Allgas Gas Network covers part of the Brisbane area (south of the Brisbane River) and the Gold Coast (extending into northern NSW). It also covers the inland city of Toowoomba and the town of Oakey. The distribution system consists of approximately 3,400 km of pipeline delivering gas to around 100,000 customers.
The Allgas Gas Network was initially subject to regulation as a covered pipeline under the Gas Code by the Queensland Competition Authority (QCA). It was then subject to full regulation by the Australian Energy Regulator (AER) under the National Gas Rules (NGR).
In April 2015, the NCC made a decision on the form of regulation for the Allgas Gas Network. The Allgas Gas Network is now subject to light regulation by the AER under the NGR.
