I don't have an exact date but I think airdrops were banned in the late 70's early 80's. I had air drops put in the Arthurs (Thwaites Plateau, Lake Rosanne and High Moor) in 1970. Parks would know but I suspect it is deep in the archives. Most of the time the air safety rules were abandoned when dropping and there was on and off flack from whatever the air safety body was in those days.
