Great mindset, Del! Being mechanically minded is a huge asset in aviation. Newcastle/Hunter Valley is a solid area for training.
My advice: don't rush into committing to a full CPL package immediately. Definitely do that test flight first (as you planned), then maybe aim to complete your RPL first to see how you handle the training load and if you still enjoy it before committing to the full professional path. Also, keep an eye on medical requirements early on, as that's one hurdle people sometimes overlook until it's too late.
Good luck with the discovery flight!
