Maritime Warfare Officer Submariner
As a Maritime Warfare Officer Submariner, you’ll be responsible for one of Australia’s most valuable strategic assets – a Navy submarine. You’ll play an integral role as a member of the sub’s command team and assume responsibility for the control, navigation, systems and safety of your submarine at sea and in harbour. You’ll report to your command team and directly to your Commanding Officer, as a leader to all personnel onboard.
What you'll do
Working in the unique environment of a Navy submarine at sea and ashore, you’ll perform a range of duties that call on your leadership abilities and training. Your day-to-day duties will include everything from leading teams of sailors to safely navigating the submarine and overseeing the use of weapons systems. On shore, you’ll participate in operational planning and gain experience across a range of different areas, including instructing, project management and career management.
Your duties may include:
- maintaining the safety of the submarine and crew
- managing and leading the crew, their activities and wellbeing
- maintaining the safe navigation of the submarine
- contributing to submarine operations, warfare activities and tactics
- controlling the vessel through surfaced, dived and harbour watchkeeping
- overseeing sensors, combat and weapon systems.
As a submariner, you'll also perform additional general duties that support the whole submarine, including:
- emergency response (damage control)
- submarine security, firefighting and replenishment at sea
- boarding party, first aid, flood repair and flight deck
- assisting with medical, ammunitioning or ceremonial duties
- shift work, or on-call duties as required.
Opportunities for progression and upskilling continue throughout your career as an officer. As you progress, the Navy will provide you with leadership, management, and specialist skills training to develop your ability to effectively manage your teams. You’ll also be provided with training opportunities to further develop your role-related expertise. This world-class training will strengthen your skillset and enable you to become an influential leader in the Navy allowing you to face any challenge, either at sea or ashore. There are also a wide variety of shore-based positions for periods when you're not posted to a submarine, including instructing (officer, mariner and submariner positions), Navy liaison positions (internationally based), operational planning, project management, career management and general managerial roles. Once trained, you’ll usually progress to a new position every 18-24 months.
As an officer in the Navy, you may also undertake a posting to an Any Officer role during your career, such as instructor/training roles and staff officer roles. This experience helps you broaden your skill set and prepare for more senior roles.
Initial and employment training occurs at HMAS Creswell, Australian Defence Force Academy (ADFA), HMAS Watson, NSW and various HMA ships. Following training, you'll be based out of HMAS Stirling, WA. There are a number of shore positions available at various locations around Australia, and a limited number of international positions. International training occurs for members selected to undertake nuclear-powered submariner training.
