To the extent that Australia loses taxing rights over its mineral products by moving to DBCFT, couldn't it just replace those by increasing taxes on minerals directly- e.g. with royalties, licenses, or with something like Norway's special petroleum tax? Since the rents associated with minerals should be location-specific.
Definitely, but it wouldn't lead to any tax being relieved at destination as that is still based on the sale price, not the income. So if taxing this rent has no cost, it could be done now - and the same loss in the tax base exists.
