I found a couple of references:
http://www.bushwalkingleadership.org.au/Home/about.htm :- "in 1971, Glen Matters, a boy from a Victorian school group, died from hypothermia on a walking trip in Tasmania. At least another ten members of the party were lucky to survive"
Brookes, A. (2003). Outdoor education fatalities in Australia 1960-2002. Part 2. Contributing circumstances: supervision, first aid, and rescue. Australian Journal of Outdoor Education, 7(2), 34-42 :- "In all three Cradle Mountain incidents parties became separated. Individuals who could maintain body heat by activity (i.e. who are not exhausted) and who expected to be able to reach shelter understandably did so, unsupervised. In Cradle Mountain (1971), the party had spread out as conditions deteriorated, but it was the students who successfully reached the hut who assisted with the rescue of those who had not...... In the 1965 and 1971 Cradle Mountain incident there were, in addition to fatalities, successful rescues of additional hypothermia victims by party members and others. Two students walked out to seek assistance in the 1965 incident, which led to the rescue of eight who had sheltered in the boatshed overnight, and four others who had spent a night in the open. Both teachers and five students suffered hypothermia in the 1971 incident; the remaining group members and other walkers brought them to a hut during the night."
which of course had me looking for Part 1: "2 teachers, 19 students. 3rd day of bushwalk, reached hut- full. 4pm continued to next hut. Snow on ground, weather deteriorated. Both teachers and 5 students hypothermic, failed to reach hut by dark. During the night hut occupants worked to get all 7 to hut. 1 student died in the hut."
And there's a part 3: "Three hypothermia incidents involved school bushwalking parties that encountered blizzard conditions. All occurred at the Cradle Mountain end of the Cradle Mountain Lake St Clair National Park (Tas) in the space of six years (1964, 1965 and 1971). The common location is probably not coincidental; risk of hypothermia is a function of both weather and terrain. Each of the incidents had the potential for more deaths. In the 1964 incident a party of 20 including 5 adults became separated in a blizzard. A student, 15, died. In the 1965 incident a student teacher died in an attempt to get a student, who also died, to shelter. In both cases most of the survivors were rescued after the alarm was raised by individuals who walked to safety. In the 1971 incident in which a student died, a teacher also became unconscious from hypothermia but was rescued. In all three cases parties separated as conditions deteriorated (this is not to imply the outcome would have been better had they stayed together – it may have been worse).

Also a bit ironic as 1971 was the year that the area or "reserve" became a National Park.
