The rights were owned by Woomera productions & John McCallum until his death in 2010. Who has the rights now is anybody's guess. The only available video copies are in the hands of the 7 network and the original film is held at the National Film and Sound Archive in Canberra.
if JL bought the rights to it's screening ...... why is it , I just watch it on you tube or you could buy it on DVD format ......... so much for rumors
