Gas transmission and distribution

Gas transmission

Natural gas is transported from the field to market by pipelines. There are 5 major natural gas pipelines in Queensland, the:

  • South West Queensland Pipeline (SWQP), running from Ballera to Wallumbilla (Roma) (937km)
  • Carpentaria Gas Pipeline (CGP), running from Ballera to Mt Isa (840km)
  • Roma to Brisbane Pipeline (RBP), running from Wallumbilla (Roma) to Brisbane (438km)
  • Queensland Gas Pipeline (QGP), running from Wallumbilla (Roma) to Gladstone and Rockhampton (627km)
  • North Queensland Gas Pipeline (NQGP), running from Moranbah to Townsville (392km).

These pipelines directly service large industrial customers and gas-fired generators. They also provide gas for localised distribution networks in and around Queensland cities and major regional centres.

In addition, the Queensland-South Australia-New South Wales pipeline link (QSN Link) between Ballera and Moomba was commissioned in 2009 and links the first 4 pipelines above to pipeline systems in the interconnected eastern gas market (New South Wales, Victoria, South Australia, Tasmania and the Australian Capital Territory).

Wallumbilla, a gas supply hub which commenced in 2014, is a pipeline interconnection point for the Surat–Bowen Basin, linking gas markets in Queensland, South Australia, New South Wales and Victoria.
