Did I bid in US dollars or Australian dollars for my high bid?

Hello Thomas,
Thank you for your question about which currency to use for your bid. We will always bid in the currency that the listing itself uses. If the listing is in Australian dollars, then the value you specify will be Australian.
For convenience, the currency is shown on your main snipe page.
Please let us know if we can assist you with any other questions, we are happy to help.
