I havent heard of anyone doing training in SE Qld, although there probably is someone. I think you can pick up alot through a little reading on the net and alot of practise though. Its probably worth going through Schomers "Factors" if you havent already (found here: http://www.lucidcafe.com/lucidcafe/cafeforum/factors.html). Then go make a stack of shots :)
The main thing I did that improved my technique was to look closely at the puck after pulling the shot and look for pits and holes that indicate channeling. Once I started looking for it I began taking more care to make sure i got rid of it and my shots improved.
The other thing is to learn something about the temperature of your machine.
