The ultimate adventure documentary about outback Aussie has to be "Northern Safari" made in the 1950's.(Available on Ebay)
A two hour film featuring Keith Adams, his wife, his sister and his dog travel from Perth diagonally across Aussie in a 1948 Buick through the Gibson Desert, Central Aussie to the Gulf of Carpenteria. Unbelievable exploits: catching sharks on handlines, hunting crocodiles, winching with a winch made from tree branches, and so on. Some of the scenes are not for the squeamish but very raw and authentic. Has anyone else seen this film. He apparently showed it throughout aussie, NZ, UK, etc. in the 60's and 70's. I've read his autobiography which is also quite amazing.
Cheers
