Aurealis Online was created in 2004 by Stephen Higgins and Dirk Strasser (Chimera Publications) as an adjunct to Aurealis magazine and in recognition of the global nature of science fiction and fantasy fandom. The site itself was designed by the magazine's long-time art director Andrew J. McKiernan.
The website's stated mission is to provide an opportunity to promote Australian writers within the worldwide speculative fiction community, while also offering a portal for news, links, and events and an archival repository.
