Currently, initial design work is taking place in Adelaide and Cherbourg, France.
Preparations for the work to move to South Australia will involve a range of training activities for Australians to ensure they achieve the necessary qualifications and develop the essential skills to undertake both detailed design and production planning.
The government said undertaking the detailed design and production planning locally will ensure Australia's sovereignty goals are met, in a smooth transition to construction of the submarines in Adelaide.
During the detailed design phase the Future Submarines will be developed and planned to a high level of precision using advanced computer-aided software, which includes the layout of all systems in each compartment of the submarine.
The announcement coincides with the visit to Australia by French President, Emmanuel Macron.
The 12 new submarines will be constructed in Adelaide from 2023. The project is expected to create almost 3,000 jobs directly and throughout the supply chain.
So far, more than 600 Australian companies have registered interest with Naval Group to be a part of the program.
