south west queensland pipeline
APA owns and operates the South West Queensland Pipeline, including the QSN Link.
The bi-directional South West Queensland Pipeline (SWQP) is a transmission pipeline comprising two parallel pipelines (400-millimetre and 450-millimetre diameter) linking Wallumbilla in South East Queensland to Moomba. It is made up of:
A diagram of the SWQP can be found here, showing:
The SWQP is adjacent to compression facilities at Moomba and Wallumbilla. These facilities largely provide compression to support transport on the SWQP (raising gas to the necessary pressure for transport on the pipeline), but can also provide stand-alone compression services. The Moomba and Wallumbilla Hubs can also provide redirection services into other pipelines as needed.
The SWQP is a non-scheme pipeline.
|Capacity and Services||
The following standard services are offered on the SWQP, subject to available capacity:
The following standard services are offered at the Moomba and Wallumbilla hubs, subject to available capacity:
A description of these services, including the Standard Gas Transportation Agreement (SGTA) can be found on the gas transmission services page.
Relevant tariffs for these standard services can be found on the current tariffs and terms page.
Non-standard services or alternative terms may be available by negotiation.
Notes on services
Interruptible services are only available while compression is fully contracted in respect of the corresponding firm service.
APA is progressively rolling out Operational Capacity Transfer service capability for compression services. APA will prioritise this service rollout in accordance with shipper demand.

Notes on available capacity
Access to westernhaul transport services on the SWQP requires gas be delivered to APA at the high pressure side of Wallumbilla (see Wallumbilla Hub diagram). A shipper may access westernhaul transport services from the low pressure side of Wallumbilla provided compression capacity is available at the Wallumbilla Hub to move to the high pressure side. Westernhaul transport from the low pressure side of Wallumbilla requires compression – please refer to our current tariffs and terms page.
Access to easternhaul transport services on the SWQP requires gas be delivered to APA at the SWQP entry from Moomba Compression Facility delivery stream on the high pressure side of Moomba Hub (see Moomba Hub diagram). A shipper may access easternhaul transport services from the low pressure side of Moomba provided compression capacity is available at the Moomba Hub to move to the high pressure side. Due to this requirement, the above schematic depicts gas only being capable of flowing out of the SWQP to the Moomba Sydney Pipeline (MSP) or Moomba Adelaide Pipeline (MAPS). Gas coming on to the SWQP from either the MSP or MAPS must be transported via the Moomba Hub to be compressed. Easternhaul transport from the low pressure side of Moomba requires compression - please refer to our current tariffs and terms page.
Available compression capacity can vary significantly depending on prevailing suction and discharge pressure at the time.

Metering and Measurement
APA requires the Gas Specification or any other quality to comply with the relevant Australian Standard (AS 4564). APA will measure and/or monitor gas quality in accordance with relevant obligations under contract. Quality obligations are outlined in APA’s SGTA.
APA has minimum credit support requirements that are a pre-condition to gaining access to pipeline services. APA’s credit support requirements are set out here.
If you are interested in acquiring services on the SWQP or at the Wallumbilla or Moomba hubs, you can contact us on 07 3323 6110 to discuss your requirements. Alternatively you may wish to email us at firstname.lastname@example.org.
We encourage potential customers to contact APA early when considering their gas supply and transport needs. Early discussion of needs improves the likelihood that APA can tailor services to meet them.
|Formal Access Request||
For APA’s non-scheme pipelines, you have a right to make a Formal Access Request pursuant to Rule 559 of the National Gas Rules. Lodging a Formal Access Request triggers a formal process of Access Offer and information exchange between APA and the potential customer. Details are in APA’s User Access Guide.
Potential customers do not have to submit a Formal Access Request to gain access to an APA pipeline.
You can make a Formal Access Request by completing in full the relevant User Access Request Form for this pipeline and emailing it to email@example.com. Complete this User Access Request Form for the SWQP, this User Access Request Form for Wallumbilla Hub services, and this User Access Request Form for Moomba Hub Services.
