I shipped a grand piano cross country for about $1,000. I could have probably strapped a couple of bikes to the top of the piano and no one would have noticed.

Actually, it's surprisingly easy to ship pianos across the country -- there are several companies that criss-cross the country with regular routes. If you're anywhere close to an Interstate, they just swing by your house, pick up the piano, and off it goes.

Don't know how that works in Australia, though.
