Go with the deal at the hobby shop. And I am sure that a city the size of Perth has an RC club. Join it and find an instructor.
There is nothing wrong with the OS40LA. It runs well and is easy to start. Mine has NEVER quit on me in flight. Hitec is a well respected radio manufacturer.
It sound like the hobby shop has a good deal going for a beginner such as yourself.
Get it and go flying!!
