Enigma was the fanzine of the Sydney University Science Fiction Association.
Published in Sydney, Australia, Enigma was released in the 1970s and 1980s. It was first edited by Richard Faulder, and then by Van Iken.
Terry Dowling, in Aurealis #30, from 2002, writes, " Richard Faulder was a long-time sf fan who was active in a number of Sydney sf organisations, including the Sydney Science Fiction Foundation and the Sydney University Science Fiction Association (SUSFA). In this latter role he edited some issues of the SUSFA fanzine, Enigma, and published some stories by a First Year student named Van Ikin. Van then became the editor of Enigma (and a friend of Richard Faulder) and retained the editorship from 1972 to 1980 (when he moved to Perth). During that time he published the earliest works of writers like Rick Kennett and Terry Dowling."
Contributing artists included Nick Stathopoulos, among others.
Enigma won the Ditmar Award for Best Fanzine in 1978.
Richard Faulder also published the title Xenophilia.
