The Illabo to Tumut Pipeline is a transmission pipeline in south-west NSW. The pipeline is owned by Australian Gas Networks (AGN) and is operated by the APA Group.

The Illabo to Tumut Pipeline is 64 km in length and has a diameter of 200 mm, and a capacity of 18 TJ/day.  It begins close to Illabo and connects the Young to Wagga portion of the APA Group’s Moomba Sydney Pipeline with Tumut. 

The Illabo to Tumut Pipeline is currently a non-scheme pipeline, and is subject to the access regime for non-scheme pipelines under Chapter 6A of the NGL and Part 23 of the NGR. On 13 December 2017, the AER granted a 5 year category 3 exemption under Part 23 of the NGR for the Illabo to Tumut Pipeline. 

As part of a partnership, Great Southern Energy Gas Networks and a Minson/Nacap joint venture constructed the pipeline in 2000.
