Moomba Sydney Pipeline and MSEP
APA is currently undertaking a project to convert the Moomba Sydney Ethane Pipeline (MSEP) into a methane transport pipeline.
The Moomba Sydney Pipeline and converted MSEP system consists of more than 2000 km of mainline and lateral gas transmission pipelines connecting SA, NSW and ACT.
With NSW being Australia’s most populous state, the MSP plays a vital role in supplying natural gas to households and businesses on the east coast.
The MSP is made up of:
- A mainline 1,300km bi-directional pipeline between Moomba and Wilton with the ability to deliver to Culcairn
- 58 km pipeline from Dalton to Canberra
- 245 km pipeline from Young to Lithgow and Bathurst
- 131 km bi-directional pipeline between Young and Wagga Wagga
- 179 km pipeline from Burnt Creek (on the pipeline between Young and Wagga Wagga) to Griffith
- 88 km bi-directional interconnect pipeline between Culcairn and Wagga Wagga (which connects to the Victorian Transmission System at Culcairn)
The converted MSEP will provide for transport of methane directly from Moomba to either Wilton to Culcairn.
At Moomba the MSP and MSEP connects with the South West Queensland Pipeline (SWQP). It provides a key link for gas coming out of Queensland to connect into the east coast grid, bringing gas down into NSW and Victoria.
The MSEP has planned capacity of up to 25 TJ/d available from 2026. This would provide total southern haul capacity of up to 590 TJ/d from Moomba.
While the main Moomba to Wilton pipeline is a non-scheme pipeline, different pipelines and sections of this system are subject to different regulations.
We work in close partnership with Traditional Owners and Elders to conduct thorough site checks and consultations. By fostering positive relationships and actively involving them in our processes, we ensure their valuable input is respected and integrated into our work.
We actively support our local community through sponsorships, including a $1,000 award for both Cobar High School and Cobar Primary School. Recently, we also contributed $2,000 to the Springhurst CFA to assist in purchasing a new trailer.
