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.
Wallumbilla Hub is the interconnection point for 9 key APA and non-APA owned pipelines in QLD. These pipelines connect gas from the Surat and Bowen supply regions to various demand centres in Greater Brisbane, Gladstone, as well as southern markets via the South West Queensland Pipeline (SWQP).
APA offers services at the Wallumbilla Hub that facilitate gas market liquidity and seamless transfer of gas between pipelines operating at different pressures. Further information about APA’s Wallumbilla services can be found in the Wallumbilla Hub Services Book.
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 tariffs and terms page.
Non-standard services or alternative terms may be available by negotiation.
Notes on services
Firm services are available over varying terms as set out on the gas transmission services page.
Interruptible services are only available while compression is fully contracted in respect of the corresponding firm service.

Steps to find 36 month Uncontracted Capacity data via the Gas Bulletin Board
Notes on available capacity
The amount of firm park or loan capacity available may be different to the amount of firm transport capacity on the pipeline that is reported in the 36-month uncontracted capacity outlook.
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 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 tariffs and terms page.
Available compression capacity can vary significantly depending on prevailing suction and discharge pressure at the time.
|Policies, Procedures and Requirements||
Metering and Measurement
APA requires the Gas Specification or any other quality to comply with the following requirements:
APA will measure and/or monitor gas quality in accordance with relevant obligations under contract. Quality obligations are outlined in APA’s SGTA (East and Central).
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 02 9275 0020 to discuss your requirements. Alternatively you may wish to email us at [email protected].
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||
Potential customers do not have to submit a Formal Access Request to gain access to an APA pipeline. If you are interested in acquiring services for this pipeline, you can contact us at the contact details above to discuss your requirements.
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.
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 protected]. 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.
|APA Financial Information Disclosure – Part 23 National Gas Rules||
APA is reporting financial information for its non-scheme pipelines — that is, pipelines that are not subject to full or light regulation, according to AER’s Financial Reporting Guideline for non-Scheme Pipelines. The financial information for the six months to 30 June 2018 and the years ending 30 June 2019 - 2023 includes Pipeline Financial Statements based on Australian Accounting Standards, the weighted average price for services on each of these pipelines, and the number derived using the AER recovered capital method (RCM).
Interested parties should read APA’s Basis of Preparation together with the completed financial information template that was developed by the AER.
In addition, APA advises in relation to RCM:
