Here's an article from Cinema Papers that covers Australian dystopian movies up until the end of the 80's. The Australian film industry was smaller and somewhat more insular then as opposed to today and through the article you can cross reference and connect people that were part of of these productions. Two significant productions from this period, Hard Knuckle and Sons of Steel, are omitted from the piece but I suspect they may have just missed representation by mere months between publishing of the article and their release dates. Hard Knuckle also features two Mad Max alum's, Steve Bisley and Kjell Nilsson.
