As Australian cinema broke through to international audiences in the 1970s through respected art house films, a new underground of low-budget exploitation filmmakers were turning out considerably less highbrow fare. Documentary filmmaker Mark Hartley explores this unbridled era of sex and violence and action and horror and outright hysteria. We have packaged a six-pack with Hartley’s wildly entertaining documentary and essential “Ozploitation” classics. We recommend starting with the doc and then working your way through. This bundle is available for purchase or as a binge-watch rental.
