All airports I have been to in Australia (Brisbane, Melbourne, Sydney, Cairns, Gold Coast) have hand checked for me, some more difficult than others to ask for it.
Small risk is not no risk. If they didn't damage then an unlimited number of passes would not affect film.
I prefer to ask when I can and have time to do so to minimise the number of passes. I just tell them I stake my living on this/professional use, and that no, a single pass isn't going to hurt, but it's already had multiple passes, and that I prefer to be safe than sorry with my work, and ask if they could kindly do an explosives swab instead of an xray.
There are also lead lined carry on bags that will attenuate (but not block) the X-Ray scans, so that the level is quite reduced and they can boost the image digitally after the pass.
