The Illabo to Tumut Pipeline is a distribution 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 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 pipeline:

• On 13 December 2017, a five year category 3 exemption under Part 23 of the NGR, which was later revoked on 23 November 2018. 
• On 26 November 2018, a new Category 3 exemption.
• On 1 March 2024, a five year Category 2 exemption.

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