Who We Are

We are natural gas distribution network owners and operators.

We are responsible for organising your natural gas connection and ensuring natural gas is delivered to your business safely and reliably.

Natural gas retailers (the name on your gas bill) use our pipeline network to transport their gas to you.

This website covers the natural gas distribution networks owned by Envestra Ltd, APA Group and GDI (EII) Pty Ltd.


Envestra is one of the largest natural gas distribution network owners in Australia. The Envestra pipeline networks deliver natural gas to over 1.1million homes and businesses around Australia. Most of the distribution networks owned by Envestra are operated by APA Group.

Envestra and GDI contract APA Group to operate their natural gas distribution networks nationally. APA Group owns and operates a network in Tamworth.
