Hi All
you can order clear ammonia in Australia from here http://www.australianhomeguide.com.au/ac.html
It's in a powder form & you make up a stock solution for daily dosing to the tank. I've used it now to cycle one of my tanks & it seemed to go well.
Hope this might help someone out. I've been looking for a source for a long time, so thought someone else might be after some too.
