Frank, this is the information I recieved from a researcher in Australia. AAOCNC- stands for Australian Army Ordnance Depot Northern Command. She further stated that when she looked at his file, this wasn't actually his posting on discharge, it was 1 Base Ordnance Depot. He was there from July 1948 until his discharge in 1952. Hope this was helpful and correspondence to her directly is Shirley Parr, firstname.lastname@example.org.
