Yes, I need a way of applying a 10% tax to customers inside Australia, and not applying it to orders from outside Australia.
For me, something that was hard coded would be fine, but I imagine that it would be more useful if it was something similar to the tax rules that can be set up in Virtuemart, where the rule is only applied if the country matches the country specified in the rule.
Was a solution found for this? I need to show the GST in the tax invoice that is produced. I am using Membership Pro also so it is similar to the feature that is available here (setting Tax amount in Configuration).
