Maybe this is another way that Perth differs from anywhere else, but with the possible exception of Neutral Zone (which I wasn't involved with), I don't know that there's ever been a coherent "media fandom" in Perth. There's an anime fan club, a Doctor Who fan club, and may still be a Star Trek fan club... but with the possible exception of SwanCon 19, I don't remember a time when they ever joined up to organize a multi-media con or any similar event.
