They pay legal tender local currencies in every countries. In Australia you can't use USD to buy anything, you have to convert it to local legal tender AUD based on today exchange rate. But gold is always valued in USD. You "WILL NEVER" see gold suddenly trading at AUD$5000 today while it's only valued at USD$1230 today, because that's not the exchange rate between AUD & USD. Hard to explain.....some may understand what I'm trying to explain, but that's the fact. Sorry to disappoint you
