On the web, prospective customers will come from the world over. To make their life easier, make sure that on every page of your website you disclose where you are located, including the country. On every page that includes a price, explain which currency that price is shown in (or, prefix the price with the currency format, e.g. $AU320, A$320 or AU$320 — depending on your preference.)

If you only ship to your own country, make this clear. If you ship to other countries, explain which countries, be upfront about shipping costs, and include an indicative currency converter (a free tool is available on xe.com.)

Not only does all this give your visitors essential pre-purchase information, but it demonstrates respect that you are not assuming your visitors are of a particular geographic region.
