One now needs a signed Marine Radio Operator's VHF Certificate of Proficiency (MROVCP). These are issued by the Australian Maritime College delegated by ACMA. I obtained mine from Marine Rescue NSW as part of a boat licence course in 2014. ("AMC is a specialist institute of the University of Tasmania" according to my MROVCP.)
