Hey Carl,
You could Jetstar to Brissie, pick it up, get it to Bryans place, fix carb issue ( shouldn't take you two more than a couple of hours), bung one of your bike's Tassie rego plates & label on it then ride it home. Shouldn't cost more than about 150 bucks, but then, there's that ferry issue to deal with.
Oh well, just a thought.
