Peter Christopher, OAM, (born 1948, Cyprus) is an Australian author and photographer who writes about shipwrecks and riverboats.
The Report of the Committee "appointed to investigate safety precautions for Scuba Divers in Fresh Water Sink Holes and Underwater Caves" which was presented to the Government in January 1974 essentially recommended non-legislative response to the problem.
The success of the program is evident with nearly four decades of low fatality cave diving following the implementation of the Report's recommendations.
A 3 Dan black belt, Christopher was the judo instructor from 1970-73 of the Legacy Junior Boys Club.
He is not a full-time author; he worked as a senior Trade Union official, with his role until mid June 2015 being the Chief Industrial Officer of the Public Service Association of South Australia.
