I'm hearing that some stocks of Astrosolar film are running low (who would have figured that! haha) but I just bought some from Twin City Cameras (also trade as Adelaide Optical Centre) on Grenfell St and they seemed to have a bit left still.
They sell it for $50 but if you buy it over the web prices approach that anyway with postage costs, plus delivery time, so if you're in Adelaide and need some in a hurry check them out. Since they know me quite well mention my name and they MAY give you a few bucks off (not guaranteed)! (I don't receive any benefit from this, only friendly banter from the staff when I head into the shop!
).
Cheers,
