The Aurealis Awards are presented annually by the Australia-based Chimaera Publications and WASFF to published works in order to "recognise the achievements of Australian science fiction, fantasy, horror writers". To qualify, a work must have been first published by an Australian citizen or permanent resident between 1 January and 31 December of the corresponding year; the presentation ceremony is held the following year. It has grown from a small function of around 20 people to a two-day event attended by over 200 people.
