The Brooklyn to Altona (Qenos) Pipeline is a transmission pipeline located in central Victoria near Melbourne. The pipeline is owned and operated by the APA Group. 

The pipeline is 5 km in length and has a capacity of 5 TJ/day. The pipeline currently transmits natural gas from the APA Group’s Brooklyn Compressor Station to the Qenos Olefins chemical plant in Altona. 

The Qenos Pipeline is currently a non-scheme pipeline, and is subject to the access regime for non-scheme pipelines under Part 10 of the NGR. 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.

On 13 December 2017, the AER granted a five year Category 2 exemption under Part 23 of the NGR. On 30 November 2022, the AER granted a further 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 Brooklyn to Altona Pipeline was constructed in the mid-1970s. In October 2014, the previously ethane supplying pipeline was refitted to supply natural gas.
