Also remember that if you're going to fly the aircraft yourself privately then you either need to charge yourself a market rate (with GST) or risk being required to pay FBT as a fringe benefit to an owner.
So by the time you've paid market rate and GST then if you're only looking for a way to save tax then you're not easily going to escape from that. What you will do is limit your personal liability if someone else crashes your aircraft and wants to sue.
Alternatively, register for GST in your own name (and ABN) and operate the aircraft through that. All the losses that Akro correctly predicts can then be offset against your own tax return instead of being locked up in a company and difficult to access.
