Gas transmission

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

• South West Queensland Pipeline (SWQP) – Ballera to Wallumbilla (Roma) (937km)
• Carpentaria Gas Pipeline (CGP) – Ballera to Mt Isa (840km)
• Roma to Brisbane Pipeline (RBP) – Wallumbilla (Roma) to Brisbane (438km)
• Queensland Gas Pipeline (QGP) – Wallumbilla (Roma) to Gladstone and Rockhampton (627km)
• North Queensland Gas Pipeline (NQGP) – 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 other pipelines in the interconnected East Coast Gas System, which includes New South Wales, Victoria, South Australia, Tasmania and the Australian Capital Territory.

Queensland's Wallumbilla Gas Supply Hub is a key gas trading exchange for the east coast. It is located at the interconnection of pipelines serving the Surat–Bowen Basin, linking gas markets in Queensland, South Australia, New South Wales and Victoria.
