The DLNG to PWC Pipeline (also known as Darwin LNG Lateral) is a lateral transmission pipeline in the north region of the Northern Territory. The pipeline comprises an upstream and downstream pipeline and is owned by ConocoPhilips Pipeline Australia. At present the only pipeline connected to the DLNG to PWC pipeline capable of the transmission of gas is the Bayu-Undan to Darwin Pipeline. The pipeline has a nameplate rating of 84 TJ per day.

The DLNG to PWC Pipeline is currently a non-scheme pipeline, and is subject to the access regime for non-scheme pipelines under Part 10 of the National Gas Rules (NGR). It was 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 upstream DLNG to PWC Pipeline:
