It's quite interesting to learn that because here in Australia we don't often hear much about how Australian movies do overseas unless they're big productions or they have big name stars or directors etc. etc.
So it is a bit of a surprise to hear that the BBC did a run on Aussie movies, particularly the lesser known ones. I suppose, if I think about it, it's got to be quite likely that some Aussie movies get shown on foreign TV but for us here, it's usually the other way round (originally TV was dominated by British movies, for the last three or so decades it's been American movies) so we don't really expect Australian movies to be doing the same thing on TV in the UK or USA.
On a somewhat related note, did the BBC ever show any New Zealand made movies from around that same era? They've certainly had some good ones. Some of my favourites include (and they could also be used for inspiring thoughts on DarkCon gaming): -
Sleeping Dogs - one of Sam Neill's earlier movies
The Quiet Earth - post-apocalyptic and I believe it was the first sci-fi movie ever made in New Zealand
and
Bad Blood although this a manhunt type movie and doesn't have anything I can recall that could be used for DarkCon gaming, I like this movie because it's rather good!
A much more recent movie that I also found excellent was
The Dead Lands and obviously there's also
Once Were Warriors but I'm pretty sure that movie is quite well known around the world, it stars Jango Fett after all
I also like Peter Jackson's earlier movies
Bad Taste and
Meet The Feebles (yes I own both as well as another early movie of his called
Braindead AKA Dead Alive) but I think all three of them are well known by now so I don't need to elaborate
Edit: Another movie from the 70s-80s period that I remember as being pretty good was
Utu
