Map of Moomba Sydney Pipeline

APA owns and operates the Moomba Sydney Pipeline system.


The Moomba Sydney Pipeline (MSP) system is a transmission pipeline system. It consists of a mainline and various laterals as follows:

  • A 1,300-kilometre bi-directional pipeline between Moomba and Wilton:
    • Non-scheme between Moomba and Marsden.
    • Scheme (light regulation) between Marsden and Wilton.
  • A 58-kilometre scheme pipeline (light regulation) from Dalton to Canberra (ICRC Annual Report Summary).
  • A 245-kilometre scheme pipeline (light regulation) from Young to Lithgow and Bathurst.
  • A 131-kilometre bi-directional scheme pipeline (light regulation) between Young and Wagga Wagga.
  • A 179-kilometre scheme pipeline (light regulation) from Burnt Creek (on the pipeline between Young and Wagga Wagga) to Griffith.
  • An 88-kilometre non-scheme bi-directional interconnect pipeline between Culcairn and Wagga Wagga (which connects to the Victorian Transmission System at Culcairn).

APA Financial Information Disclosure – Part 23 National Gas Rules

APA is reporting financial information for its non-scheme pipelines — that is, pipelines that are not subject to full or light regulation. The financial information for the six months to 30 June 2018 and the year ending 30 June 2019 includes Pipeline Statements, the weighted average price for services on each of these pipelines, and the number derived using the AER recovered capital method (RCM).

Interested parties should read APA’s Basis of Preparation together with the completed financial information template that was developed by the AER.

In addition, APA advises in relation to RCM:

  1. The assumed initial capital structure is 40% equity and 60% debt. The level of equity will increase in circumstances where there is a shortfall in annual revenue.
  2. The return on equity is a commercial return applicable in a workably competitive market. Currently, this return for an established pipeline is in the range of 9-11%, depending on factors such as risk, terms and counterparty.
  3. The cost of debt is based on a 10-year rolling average of a market rate applicable for an entity whose business is solely the ownership and operatorship of the particular pipeline.
  4. APA has engaged with the AER on its approach to reporting operating costs and shared support costs (equivalent to corporate overheads) in the Part 23 reporting. In the 2019 (revised) Part 23 reporting, operating costs and corporate overheads are reported at actual cost, applying the same cost allocation methodology as has been applied in recent AER-approved access arrangements. This approach reflects the cost savings that APA achieves as a result of operating a conglomerate business encompassing a number of regulated and unregulated pipelines, network businesses, power stations and renewable energy facilities. The Basis of Preparation contains more information on this matter.
