Brisbane (South), Gold Coast, Toowoomba and Oakey Gas Distribution Network

APA operates and has an ownership interest in the natural gas distribution network in the Allgas Gas Network in Brisbane (South), Gold Coast, Toowoomba and Oakey. Gas retailers use this network to transport gas sourced by them to customers connected to the Allgas network. Some large industrial gas users may also use the network to transport gas sourced independently of a retailer.

On this page we present information for energy retailers and large gas users who wish to use the network to transport gas for which they have contracted supply independently of a gas retailer.
