There is a movie just released in the cinemas here called "Not Quite Hollywood - The Wild, Untold Story of Ozploitation".
http://www.imdb.com/title/tt0996966/
It is a documentary on 70's and 80's Australian feature films. It features movies like Mad Max, The Man From Hong Kong, and many other Australian movies of the era, with interviews and behind the scenes stories. Sounds like a great documentary.
