If the Australian Navy is anything like the British navy, getting sailors into the submarine service and getting them to stay there is awfully tricky. The RN tries very hard to make submarine service all volunteer, which constrains the pool further. By and large, it's a far less pleasant working and living environment than a surface vessel, and a number of submariners also cite the massively constrained communications as a reason for being thoroughly sick of it. Extra pay only goes so far.
