Wow. Trekdom in Australia is normally a very underground thing. It certainly doesn't seem to be as mainstream as it is in the UK or Europe. You rarely ever hear people talk about it here, and if they do, its normally derogatory talk.
Umm, excuse me?
Not in my experience. Or at least, it certainly wasn't underground in the 80s and 90s.
I ran a Star Trek club in Sydney, ASTREX, entering as member #222 in 1980 and, by the time TNG was at its peak, we had over
1000 members. While Australian's are great a good-natured digs at almost anything, I encountered very few negative comments about ST here. Melbourne had (and still has) a club called AUSTREK, and they had good numbers, too. Every capital city had a ST club, and there was even an Australian Official ST Fan Club, but the politics involved in that tended to kill off interest for many fans.
Mind you, after a brief attempt at running TNG in prime time (the tapes were already out on sell-thru), Aussie TV buried ST in a late night timeslot, so it certainly slipped out of the collective consciousness of average Aussies. Especially with kids, unless their parents are already fans who taped episodes or buy boxed sets of DVDs.
So I don't believe the situation here is all that different to parts of the USA. Galaxy Bookshop, here in Sydney, continues to maintain a huge ST book section, and new ST novel titles are stocked by chains such as Dymocks and Borders.
I might mention - for those too young to remember - that when ST: TMP was imminent, in 1979, one of our Sydney newspapers ran a series of five daily double-page centrespreads (ie. in our biggest circulation afternoon newpaper). The reporter was Australian James Oram, a highly respected journalist, who had flown to LA to do a set visit. Big bikkies! Then Paramount brought out Persis Khambatta and DeForest Kelley to promote the movie. The novelization was being sold in display racks at supermarket checkouts. ST was no secret Down Under!
it's always been hard to be a Trekkie in Australia. Hopefully, Abrams' film will change that attitude.
For some reason, in Oz, it seems Star Wars is OK, but Trek is nerdsville and to be avoided at all costs.
That has
never been my experience, although SW is certainly very popular with young people, and most of today's kids simply don't get exposed to ST.
