Hmm ... didn't realise importing into Oz was much harder than exporting.
Shipped my Pan from Brizzy to UK without any real issues.
Filled in one form, handed rego plates back to DMV, received a confirmation e-mail, and that was it - free to ship the bike out of Oz.
UK import approval took a little longer though ... ...
If I were you, and for the sake of $50 AUD, I'd take the first step and register your import request. - it will either be granted or declined.
If granted, then you have to fill in more forms and deal with all the different government departments, then physically get the bike there and through customs.
Once in country, and depending on which state you're based in, theres also the RWC, CTP, and Rego fees
Other option is to sell your bike and replace it once in Oz - loads of Pans for sale online.
Whatever you decide, Oz is a fantastic country for riding.
