I sent a set to New Zealand a couple years ago, no big deal, I used the Post Office and it was not a problem, nor expensive. Just a form to fill out while your there.
here is the international shipping form link https://webapps.usps.com/customsforms/cp72package_information_w.jsp you can get the pouches the labels go into at your postal branch
Byron both usps( post office) and UPS want an astronomical fee to ship these things. a box 23"x23"x8" that weighs 15 lbs costs over 200.00 to ship :af:
Dude---you need to recheck the rates to Australia....you must have punched a wrong key. I calculate half that rate using Priority Mail International USPostal. http://www.usps.com/tools/calculatepostage/welcome.htm?from=home_header&page=calculatepostage
I've had it happen to me on Fedex's site a couple times and DHL's (when they shipped here)....put in a bunch of accurate dimensions and it shoots back a crazy number. I'd wait a day and recheck and get a proper number. One time I just had to take the part up to DHL and have them run it in their computer...ended up with a much lower number.
