The Federal Government is seeking to develop two bases in Australia - one on the west coast and one on the east coast - with capacity and capability to house nuclear-powered submarines (SSNs) as part of the AUKUS.
The HMAS Stirling Navel Base, located in Perth, will be expanded to include wharf upgrades, operational maintenance, logistics and training facilities, as well as opportunities for supporting infrastructure outside HMAS Stirling.
The expansion is estimated to cost $8 billion and be completed over 10 years.
