The Darwin Distribution System is a distribution network in the Northern Territory. The network is owned and operated by N.T. Gas Distribution, a subsidiary of the APA Group.

The Darwin Distribution System is 19 km in network length. It serves the Darwin area.

The Darwin Distribution System is currently a non-scheme pipeline, and is subject to the access regime for non-scheme pipelines under 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 Darwin Distribution System:

• On 13 December 2017, a five year Category 2 exemption under Part 23 of the NGR.
• On 30 November 2022, a five year Category 2 exemption under Part 23 of the NGR. Due to reforms to the NGR, the exemption transitioned to a Category 2 exemption under Part 10 of the NGR.

The DCGBP was initially subject to regulation as a covered pipeline under the Gas Code by the ACCC. However, no access arrangement was lodged with or approved by the ACCC. In May 2003, following a recommendation from the NCC, the relevant minister decided to revoke coverage of the DCGBP. At the time that coverage was revoked only small volumes of gas were being transported by the DCGBP.

The Darwin Distribution System was completed in 1996.
