Unless you are acquiring the Streak Shadow at a give-away purchase price in the UK (like, next to nothing) I'd suggest you investigate what a 27 year old similar ultralight w/ 700 hrs would cost you in OZ dollars on your Perth doorstep. No problems with training in the S.S. here once you've found an instructor, as you would be declared the 1st owner/builder once it's brought on the RAA register. Though I didn't need or plan to flight-train in it, I brought a kit-built biplane from USA into Perth a couple of years back (me being the 4th owner) and had no problems w/ import and RAA registration however, Aust Quarantine have very inflexible (but manageable) regulations re cleanliness and packing for import. Poncing around with export/import agents, container shipping, local transport both ends, clearing fees, etc, etc, ad-infinitum, cost me about (A)$9 grand. If you proceed, I'd suggest you first contact Tech Mgr, Recreational Aviation Aust to get the precise & up-to-date requirements for all aspects of your plans, then get comparative figures from at least two agents who would work on your behalf (then add about 3 grand). As previously said, methinks you'd have to have an extremely specific love for that very aircraft in order to justify the end result. PM me if you need any further discouragement. cheers Riley
