Osborne - Nuclear Submarine Construction Yard Project

The proposal

On 14 March 2023, the Commonwealth Government announced the pathway for the acquisition of a conventionally-armed nuclear-powered submarine capability for Australia, part of which involves Australia building such submarines in South Australia.

In order to consider the main construction elements, such as; the Nuclear-Powered Submarine Construction Yard (SCY), launch and berthing facilities and associated infrastructure including potential impacts of the development on both land and to marine waters, the Minister for Planning has declared that an impact assessed process under s.108(1)(c) of the Planning, Development and Infrastructure Act 2016 will apply, requiring the preparation on an Environmental Impact Statement (EIS).

Australian Naval Infrastructure (ANI) is seeking to develop the SCY at Osborne, South Australia, and will be responsible for preparing the EIS.

The proposal includes the following components:

  • development associated with the construction and operation of the SCY
  • development associated with any change in the use of land and coastal waters
  • development associated with the construction, installation or provision of specified infrastructure, facilities and services (outlined in the declaration notice)
  • development (including development undertaken on land or coastal waters in the State, inclusive but not limited to the land and coastal waters specified in Schedule 2) associated with any excavation or filling of land associated with any development
  • development (including development undertaken on land or coastal waters in the State, inclusive but not limited to the land and coastal waters specified in Schedule 2) associated with the division of land associated with the development
  • any related or ancillary development (including development undertaken on land or coastal waters in the State, inclusive but not limited to the land and coastal waters specified in Schedule 2).

The above components are subject to any terms or limitations within the notice, whilst the gazettal also excludes some related works from the EIS process, namely the relocation of existing electricity transmission lines, substation and gas pipelines; works and activities associated with existing port and harbour operations; and certain road works relating to specified land.
