VH-MRD served with the Australian navy from 1953 to 1963. It had an RAAF serial - the A11 prefix was applied to the RAAF's wartime Taylorcaft Austers - throughout its navy career. -MRD was civil registered in December 1963 and withdrawn from use in 2015. By then it had been transformed into the Beach Hawk, a 200hp Lycoming-powered two-seater which retained only the wings, tailplane and general configuration of the original aircraft. It is considered to be a new type, in the amateur built category, and has the MSN 1.
