Unlike New Zealand where the Hiller 12E was quite popular, Australia has never had many Hiller 12s or 1100 on register. I don't know about the current register though. I learnt to fly on the 12E and believe it was a lot better than the 12C which I never flew. Due to the lack of Hillers here, there wouldn't be too many pilots endorsed or current, so trying to earn money from one could be difficult. Some were used for crop spraying by a East Coast company but I've lost track of them.
Hope that helps a bit!
