The first Australian Super 8 fan film I saw was from the Melbourne Star Trek Club, Austrek, called "City on the Edge of the Yarra" (as in Yarra River) and it had some rather bizarre "Rocky Horror Picture Show" influences when Kirk and Spock stumble across a science fiction convention. There was also a SF film made - but never finished? - by Sydney fan John Parks. It featured some "Star Wars" parodies, such as robots C-Me-P.O.Q. and RU-One-Two, and a life-size Dalek race, if I recall correctly. I did eventually see snippets of the raw footage, and it was fun recognising the early work of several fan colleagues, performed years before I'd discovered active fandom, and met all these people, in 1980.
My club, Astrex, in Sydney, had one group of enthusiastic members who made some fan films with me in the 80s. I've mentioned several of them here before. Mostly, our fan films were videoed parodies of then-contemporary television game shows, as performed live at fan gatherings. These were then edited, given opening credits, and sometimes had reshoots and SPFX added. Some of our efforts were made as proper short films, though, and had scripted dialogue and even storyboards, etc.
Our fan films included:
* The Australian Science Fiction Media Award-winning "Sale of the 23rd Century", hosted by Therin and Tharrah the Andorians, and Tackee the green Orion slave girl. (This was many years before Senator Therin Sr cameoed in "Starship Exeter: The Savage Empire".)
* "Starfleet Blankety Blanks", hosted by Grol the Tellarite and Tackee.
* "Cometcon Blankety Blanks", hosted by Strop the Visitor and Tackee.
* "Timewarped" - Doug and Tony of "The Time Tunnel" arrive in Sydney, Australia, just in time for a science fiction media convention. Ann twiddles some knobs but is unable to assist them.
* The Australian Science Fiction Media Award-winning "Perfect Botch", hosted by Reed, Sue and Johnny of "The Fantastic Four", complete with an inserted segment about Spock and T'Pring's romantic date, which they'd supposedly won in the (phantom) previous episode. Segment had Therin and Tharrah as chaperones. Live "mystery guest" contestants were Tackee and The Thing.
* "Free Maltz", the post-"Star Trek III" story of Maltz's escape from a Vulcan prison cell. A standalone short, but also used as introduction to:
* "The Nearly-Wed Game", hosted by Maltz and guest-starring pro actor Brian Croucher of "Blake's Seven" as Travis!
* "The Naked Never" - a Season One TNG skit videoed on a full-size TNG bridge (mocked up in one weekend out of huge sheets of corrugated cardboard).
* "Star Trek 5.5" - the making of the film they were never game to let William Shatner actually direct, and on a shoestring budget even less than "Star Trek V: The Final Frontier".
I'm not sure if the parody game shows "It's in the Beg" (performed live in New Zealand, hosted by The Flash) or "Tribble Lotto", featuring Walter Koenig (also performed live in Sydney), were actually preserved for posterity.
My production team was known as Harpic Productions. Yep, flushed with success, our films made us blue in the face. (And had some toilet humour.)
I also once participated, as script contributor and makeup artist, on a film short made by a group of Macquarie University film students in the 90s. It was called "Lost in Fantasy" and is perhaps closer to an Australian docu-drama than a true fan film.
More info, and I'll add pics, dates and details there when I can.
