You should be able to find everything you need in OZ, even in Adelaide!!!!

Suggest that go to a newsagent and pick up a copy of Airbourne to find your nearest hobby shop. Even if you can't find one locally there are a number in Oz that will mail order

Getting stuff mail order from the US is OK if you know what you want, but you could get a lot of good advice from a decent hobby shop.

I'm not up to speed on what's the best trainer, engine wise I would look seriously at a Thunder Tiger 46PRO. This will not only fly a trainer but will take you a long way further (and if you give up it will be easier to sell than an LA40)
