Tax by country

Hi,

I'm using the Tax.CountryStateZip tax provider. I'm just testing and I have German, US and Australian customers, so I've set up a tax rate for each one. Tax is based on default address.

Problem ist, a customer with "Australia" as country has the following shopping cart:

Sub-Total:  €10.00 incl tax
Shipping:   €0.00
Tax 19% :   €1.60
Total:   €10.00

I configured the tax for Australia with 15% (just for testing), but there is 19%.

Thanks for help!
