Fishing - Fly fishing in QLD Australia??

Thanks to everyone for their help with my last post. I have a little of a
problem though as I am based in Queensland Australia, so there is precious
little opportunity for me to try any freshwater fly fishing. Are the
principles of fresh and sal****er fly fishing similar or are they two
distinct and different styles of fishing? Is the equipment that is required
similar? And finally, is there anyone out there who is based in the same
area as me and would be willing to help a clueless beginner? Or does anyone
know of any Queensland fly fishing clubs as I haven't been able to track any
down on the net.
