Bearing in mind the conversion rate. One Australian Dollar is equivalent to 0.76 American Dollars. So $100 in the Aus would be $76 in the US.

Unless this was already taken into account.

EDIT: And for my nation's currency, things currently stand at 0.76 Great British Pounds to the American Dollar, and 0.58 GBP to the Australian Dollar. Of course, this is after my nation's stupid and ridiculous decision to leave the European Union. Our currency was even stronger before that.
