The Western Network Laterals are transmission laterals located in central Queensland. They are owned by Australia Pacific LNG (APLNG), which is a joint venture between Origin Energy, ConocoPhillips and Sinopec.

The Western Network Laterals comprise the Spring Guilly to Taloona, Eurombah and Fairview to Spring Gully laterals and Spring Gully Interconnect. The Eurombah Lateral connects the Eurombah Creek gas processing facility (GPF) to the Reedy Creek hub. The Fairview to Spring Gully lateral connects GLNG's Fairview GPF to the Spring Gully pipeline compression facility (PCF). The Spring Gully Interconnect joins the Spring Gully Hub to the Spring Gully PCF. The Spring Gully to Taloona lateral connects the Spring Gully PCF to the Eurombah Lateral, with a connection from Taloona GPF.

The Western Network Laterals have an overall length of approximately 115 km, with a maximum diameter of 600mm and maximum capacity of 500 TJ/day. They have the following individual characteristics:

• Eurombah Lateral - approximately 60 km in length, 600 mm in diameter, and with a capacity of 500 TJ/day
• Fairview to Spring Gully - approximately 28 km in length, 450 mm in diameter, and with a capacity of 316 TJ/day
• Spring Gully to Taloona - approximately 26 km in length, 450 mm in diameter, and with a capacity of 500 TJ/day
• Spring Gully Interconnect - approximataly 1 km in length, 450 mm in diameter, and with a capacity of 150 TJ/day.

The Western Network Laterals are currently non-scheme lateral pipelines, and are subject to the access regime for non-scheme pipelines under Part 10 of the National Gas Rules (NGR). They were previously subject to the access regime for non-scheme pipelines under the former Part 23 of the NGR, which was replaced by Part 10.

The AER has granted the following exemptions for the Western Network Laterals:

• On 26 February 2018, a five year Category 1 and Category 2 exemption under Part 23 of the NGR.
• On 30 November 2022, a five year year Category 1 and Category 2 exemption under Part 23 of the NGR. Due to reforms to the NGR, these exemptions transitioned to a Category 1 exemption under Part 10 of the NGR.
