p.s. Depending on where you are living in Sydney the Primrose Park Photography group may also be of interest to you. It has a pretty good traditional darkroom and if you join the club I believe the cost is very reasonable and access is quite flexible. Tony Peri is one member I know there who is active in the club and a traditional film shooter so feel free to contact him and make some further inquiries about the darkroom.
Johnny, where in Melbourne are you, and do you have wheels?
Whoops - sorry I missed the second post! Not as familiar with the Melbourne scene. I understand Melbourne Camera Club still has darkroom facilities.
If you find out tomorrow you've actually been posted to Brisbane, all hope is lost!
