Subject Land

Nuclear-Powered Submarine Construction Yard at Osborne


What is proposed?

The Australian Government will begin building conventionally armed, nuclear-powered submarines by the end of this decade. The preferred site for construction is near the existing Osborne Naval Shipyard, about 19 km north-west of the Adelaide CBD.

We are seeking feedback on the Environmental Impact Statement for building and operating the Nuclear-Powered Submarine Construction Yard, associated launch and berthing facilities, and other infrastructure needed on site to build the submarines.

The Environmental Impact Statement, prepared by Australian Naval Infrastructure (ANI) identifies and considers potential impacts due to the development, its operations and any associated changes in land use, both on land and in coastal waters.

This includes considering impacts on plants, animals, heritage, community and the economy and how these impacts can be mitigated or minimised.

Background

In 2023, the Australian Government announced plans to build conventionally armed nuclear-powered submarines in South Australia as part of the AUKUS agreement.

Several approvals are required for the development to occur. Some approvals are assessed and issued by the South Australian Government and others by the Australian Government, while aspects such as nuclear licensing are assessed and approved by other regulatory agencies and licensing bodies.

South Australian Government approvals

The state-based development application for the proposed Nuclear-Powered Submarine Construction Yard project has been declared an Impact Assessed Development by the South Australian Minister for Planning.

This is the most rigorous and comprehensive level of development assessment in South Australia and is reserved for projects that are of economic, social or environmental importance to the state.

The State Planning Commission released the assessment requirements (PDF, 986 KB) for the project in August 2024, which outline and address the main environmental, economic and social impacts that might arise from the project.

In response to these requirements, ANI has prepared the Environmental Impact Statement, in-line with South Australian legislation.

ANI is an Australian Government business enterprise, responsible for developing and managing infrastructure for the submarine-building program. They submitted the development application and prepared the Environmental Impact Statement for the Submarine Construction Yard.

Australian Government approvals

The Australian Submarine Agency (ASA) is leading a separate strategic assessment process to consider and assess the impacts of the Submarine Construction Yard’s development and operations on nationally and internationally listed plants, animals, habitats and places under the Environment Protection and Biodiversity Conservation Act 1999.

Consultation on this Australian Government process is being undertaken at the same time as the South Australian Government’s consultation on the Environmental Impact Statement.

For more information about the Australian Government strategic assessment process and consultation, visit the ASA website.

Have your say

Feedback is encouraged to be submitted via the YourSAy website.

Feedback can also be submitted by:

  • completing the PlanSA online submissions form

  • emailing SPCreps@sa.gov.au (subject: Submarine Construction Yard EIS submission)

  • Posting your submission to:
    Attention: Robert Kleeman, Manager Crown and Impact Assessment
    Planning and Land Use Services
    Department for Housing and Urban Development
    GPO BOX 1815
    ADELAIDE SA 5000

Submissions will be published on this website and the YourSAy website, including company details, but personal details, such as your name, address, email or phone number, will not be published.

Next steps

All feedback will be received and collated by PlanSA and provided to ANI for their consideration and review.

ANI will then prepare a “response document”, which outlines the feedback received, addresses issues raised during consultation (including mitigation and management measures) and outlines any changes to the project.

The State Planning Commission will then consider the whole proposal, including the Environmental Impact Statement, council and state agency comments and public feedback, and prepare an assessment report.

The Commission will provide the assessment report with recommendations to the Minister for Planning for consideration in making a decision on the proposal.

The response document, public submissions and assessment report will be published on this website and the YourSAy website.
