That is a big loss to take, and it isn't right by all means. I've been there with your frustration, with the credit card charge backs, even after a month or so. Had you had the delivery confirmation, even to Australia, you'd won the case. Don't be cheap with postage when it comes to higher priced items. You are the seller and are the one to determine these shipping costs worldwide. I have shipped a $500 Rolex (without strap and winder) to New Zealand before, I shipped it with Fedfex with delivery confirmation, and the buyer didn't mind spending extra money on shipping this valuable tem. You need to understand the policies for your seller protection, and use the appropriate shipping methods and costs to each country.
