In 1993 he was awarded a National Medal of Australia for Service. In 1999 he gained a Master of Science degree from the University of New South Wales at the Australian Defence Force Academy in Canberra.

He is the author of a number of books, technical manuals, and of articles for technical magazines. At the time of writing he is retired.
