The Victorian Transmission System (VTS), also known as the Principal Transmission System (PTS), or GasNet system, is an operating pipeline system in the state of Victoria in Australia.[1]


The pipeline system is located in the Australian state of Victoria. The route below is adapted from the Australian Government's Oil and Gas Pipelines database.

Project details

  • Owner: The APA Group
  • Operator: Australian Energy Market Operator (AEMO)
  • Capacity: 976.25 million cubic feet per day / 1030 terajoules per day[2]
  • Length: 2035 kilometeres[2][3]
  • Status: Operating
  • Start year: 1969


The Victorian Transmission System (VTS) began in the 1950s and comprises approximately 1993 kilometers of high-pressure gas transmission pipelines, serving approximately 1.4 million residential consumers and 43,000 industrial and commercial users, with a capacity of 571.32 million cubic feet per day.[4]

Gas can enter or exit the system from the Longford gas plant and the VicHub in the east, Culcairn in NSW, the western underground gas storage (WUGS) facility at Iona, the SEA Gas Pipeline, Otway Gas Plant and Mortlake Pipeline through their connection to the SEA Gas Pipeline at Port Campbell, the Pakenham facility and the Dandenong LNG facility. Gas can also be injected from the Tasmanian Gas Pipeline (TasHub) into the VTS at Longford. Gas is principally sourced from offshore gas fields in the Gippsland, Bass and Otway basins.

The capacity of the VTS has been progressively expanded between 2014 and 2017 to transport additional gas between NSW and Victoria at Culcairn. In 2015, additional capacity on the South West Pipeline was added for gas flows from the facilities at Iona and the SEA Gas Pipeline at Port Campbell.[3]
