Science fiction looks into the future, or at what could exist, given what the human race knows or can imagine about the universe; or it looks at different versions of our past and present. Horror looks at the supernatural, or at particularly disturbing versions of what can exist, given the perversions of human nature. Fantasy looks at worlds or subject matter which can't exist, which we acknowledge as impossible. All are literature of ideas, with Australian writers drawing on the vast, often unforgiving, landscape we live in, the multi-cultural nature of the society around us and the lessons we're trying to learn from our history.
