Buying film in Australia is no longer a consumer purchase - it's an investment.
Alas, film here is a niche product now. Many young photographers I know bought a film camera, played with it for a few months, and then either put it away or sold it. It's a style thing, at least in Melbourne. Weekend walks in the city with your Nikon f-whatever.
The cheapest I can buy cassettes of Ilford (my past favorite was HP5) is $15. Online from a trusted supplier. 120, I don't have my own mint at home, so nyet to that.
Film canisters and Kodak slide boxes sell on Ebay. An ex-film photographer I know put 100 of his on the Big E at AUD $5.00 each - and some sucker bought them all. One born every minute, they saw him coming. With my stash of those beaut yellow boxes, I'm in like Flynn, as the locals say here. (For you non-Aussies, it's a popular Aussie expression, referring to Errol the late actor who was known for his rampant 'womanizing' and, as his biographers say, his 'manizing' also.)
I still have a reasonable film stash in my darkroom fridge, along with FB enlarging paper I will likely never use and (in a separate fridge) allso a huge supply of Ilford Galerie (the original stuff, almost as good as Kodak Azo) in 11x14 and 16x20, which I bought in 2000 from a shop in Melbourne that was about to close and the owner wanted quick cash, so I got it as a good price. I test it every few years and it's as good (almost) as the day it came off the Ilford assembly line. My partner is keen for me to dispose of those and get rid of the two fridges, so an eBay sale may be in the offing. Watch this space.
Nowadays I use maybe 10-12 rolls every year. I like using my manual/mechanical cameras, but my basic problem is that, given my usual types of photography (mostly static), I can just as easily do all my images with digital, at far cheaper cost.
As for film, every time I try to count my stash I get a different number. Likely about 100 rolls of 35mm in cassettes, four or five Kodak bulk rolls, about 50 120 roll films.
I must add a note to the instructions to my executor to sell all this at top $$ prices, after I've carked...
