We ship worldwide using UPS. We automatically calculate import duty and taxes on international orders at checkout. The taxes and duties are the ones charged by the government of the shipment's destination country. If you are shipping to Australia, you will be charged Australian taxes and duties, if you are shipping to Canada, you will be charged Canadian taxes and duties, and so on. If we didn't charge these when you checkout, you would have to pay them, plus penalties in some cases, when your shipment enters the country, which will probably cost you more money and delay the arrival of your shipment. Most governments' border enforcement agencies have websites explaining their tax and duty policies, if you want to know more about how your country's taxes and duties are calculated.
