Hi,
If you are up the North Coast way you should get in contact with the fly club - saltwaterflyfishers.org They are a really helpful bunch of people and very passionate. You should also consider getting some professional casting lessons as it helps to learn properly and not pick up bad habits at the beginning. There are a few casting instructors up your way and the club can put you on to them, alternatively there are a few in Brisbane as well.
Cheers,
Janelle
