Dave, really nailed it. My story was similar.
Although they don't offer much of a website, I did notice that EAA Chapter 1308 is located in Toowoomba.
http://www.1308.eaachapter.org/about.htmI have no idea how far that is from your home, but these chapters can be great places to learn skills like fabric work, bucking & riveting, welding and whatnot. Let the chapter know what your interests are, and they'll more than likely invite you to lend a hand the next time a member's project needs work.
I've also learned a few tricks for the shop by watching "Hints for Homebuilders": Over 300 videos on aircraft construction techniques...courtesy EAA:
