Osborne Submarine Construction Yard

Overview

Australia will begin building its first SSN-AUKUS in Osborne, South Australia by the end of this decade. Construction will be supported by an expansion of the existing Osborne Naval Shipyard Area to support the facilities and infrastructure required to build the first SSN-AUKUS, referred to as the Submarine Construction Yard (SCY).

The preferred site for the SCY is situated north of the existing Osborne Naval Shipyard on the Lefevre Peninsula, approximately 19 km north of Adelaide in South Australia. Osborne will be the home of Australia’s next generation submarine build and will become one of the most advanced technological hubs in the world.

To support the planned construction and operation of the SCY, as well as the future needs of the community, preliminary enabling works will optimise access routes and traffic flows around the site. The relocation of above and below ground utilities will ensure that future developments are safe and unimpeded whilst maintaining provision of power to the Osborne Naval Shipyards and surrounds.

The Commonwealth has appointed Australian Naval Infrastructure Pty Ltd (ANI), as an Australian Government Business Enterprise to be the Australian Submarine Agency’s (ASA) design and delivery partner for the project.

Strategic Assessment

The Department of Climate Change, Energy, the Environment and Water (DCCEEW) and ASA agreed on 24 November 2023 to undertake a Strategic Assessment of the SCY as defined under Part 10 of the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act).

The Strategic Assessment considers and assesses the impacts of the construction and operation of the SCY on protected matters as the ASA seeks to deliver conventionally-armed, nuclear-powered submarines.

The Strategic Assessment Agreement includes the development of:

  • Terms of Reference (ToR) – describes the assessment requirements of the Strategic Impact Assessment Report.
  • Plan – describes the kinds of activities that will be undertaken as a part of the construction and operation of the SCY.
  • Strategic Impact Assessment Report – assesses the impact of the activities against the assessment requirements described in the ToR.

The Strategic Assessment process includes:

  1. Public comment on the draft ToR for a minimum of 28 days.
  2. Public consultation of the Strategic Impact Assessment Report for a minimum of 28 days.
  3. Consideration of the Plan and Strategic Impact Assessment Report by the Minister for the Environment.
  4. The Minister for the Environment decision whether to approve the activities described in the Plan.

Public comment

The draft ToR developed by DCCEEW and ASA, describing the assessment requirements of the Strategic Impact Assessment Report, is open for public comment.

Draft Terms of Reference (PDF 288.41 KB)

The public comment period is open until 28 January 2024.

Comments can be registered via email to asa.osborne.enquiries@defence.gov.au.

Element Status Timeline
Preliminary enabling works

The ASA submitted a Referral under EPBC Act Part 7 to 9 for the development of a car park, pedestrian bridge and grade separated road to DCCEEW.

The delegate of the Minister for the Environment and Water decided on 8 December 2023 that the proposed action under referral (2023/09662) is a not controlled action if taken in a particular manner. This means that, provided the action is taken in accordance with the particular manners outlined in the referral decision, it does not require further assessment and approval under the EPBC Act before it can proceed. The referral decision and further details are available on the EPBC Public Portal.

EPBC Act Referral Decision received 8 December 2023.
