Collins Class Submarine - Operations and Deployments

Operations and Deployments

The entire class is based at HMAS Stirling, also known as Fleet Base West, which is located on Garden Island, off the coast of Western Australia. The decision to locate all six submarines at Stirling was prompted by the lack of suitable long-term facilities on the east coast of Australia (although individual submarines can use Fleet Base East in Sydney Harbour as a forward staging facility), and the proximity to Australian offshore interests, including most of the nation's external territories, the oil and natural gas resources of the North West Shelf, and the Indian Ocean sea lines of communication, through which the majority of Australia's seaborne trade passes. The submarines' primary missions are patrolling the waters of Australia and nearby nations, and gathering intelligence through the interception of electronic communications by foreign nations and the deployment/retrieval of special forces operatives.
