Ozploitation films are exploitation films – a category of low-budget horror, comedy, sexploitation and action films – made in Australia after the introduction of the R rating in 1971. The year also marked the beginnings of the Australian New Wave movement, and the Ozploitation style peaked within the same time frame (early 1970s to late 1980s). Ozploitation is often considered a smaller wave within the New Wave, covering a wide range of genres from sexploitation, biker films, horror and even martial arts.
