Map of Carpentaria Gas Pipeline

APA owns and operates the Carpentaria Gas Pipeline.


The Carpentaria Gas Pipeline (CGP) includes the 840-kilometre mainline, the 96-kilometre Cannington lateral, the Mica Creek metering facility and the 6 kilometre Mount Isa lateral.

This transmission pipeline transports gas from the South West Queensland Pipeline at Ballera in south west Queensland to power stations and other customers in Mount Isa and the surrounding Carpentaria mineral province.

The CGP will also soon be an important link between Northern Territory gas fields and the east coast market via the Northern Gas Pipeline, expected to be completed in 2018.
