What does your itinerary look like? I'm in Victoria right down south. I've just rearranged my house to accommodate a new enlarger so my "darkroom" is now in the spare room rather than the laundry meaning that prints are dumped in a bucket and held there until the end of my printing session to be washed in the other room. So, that being said, I have a darkroom if you don't mind ad hoc I also have a tank and chemicals for you to dev black and white film. I just read your intro thread where you were looking for ideas for developing film on the road. Anyway, while I can't help you out with developing colour, there is a local lab for that.

Let us know where you're travelling specifically. There may be others nearer to your destinations (and most definitely better set up than I am) who can help you out, too.
