The Southern Cloud, a small plane, encountered very severe weather conditions while flying from Sydney to Melbourne. It had no prior knowledge of the severe weather of due to the lack of a radio. The plane crashed and never reached its destination. The wreckage of the plane was found twenty-seven years later by a bushwalker in dense steep bushland near Tumbarumba NSW.  Of the eight people onboard there were no survivors.

The accident was one of the first major passenger aircraft accidents to occur in Australia. Without the access roads installed for the Snowy Hydro Power Scheme, it seems unlikely that the wreckage would have been discovered till decades later. The wreckage captured the interests of the nation and had been gradually scavenged with some pieces being returned to museums over time. To this day it remains a memorial unmoved upon the mountainside.
