It is convenient to consider first whether the items of printed matter, whether because they had no discernible sale value or because they were unsaleable, were such as to be outside the notion of "goods manufactured in Australia". Given that s. 17(1) applies to "goods manufactured by a taxpayer and applied to his own use" and that by s. 17(2) that reference extends to "goods manufactured and applied to his own use, whether or not the goods are of a class manufactured by the manufacturer for sale", there is no warrant (whether by reason of the reference in that sub-section to "sale value" or otherwise) for excluding from the ambit of the word "goods" as used in s. 17(1) of the Act goods which are unsaleable or goods which have no discernible sale value. However, it has long been accepted that the expression "goods manufactured in Australia", even with the aid of the definitions contained in s. 3(1) of the Act, does not extend to every object transformed or brought into existence by a physical process or operation. See, e.g., Adams v. Rau [1] and Federal Commissioner of Taxation v. Rochester [2] . So far as the question turns on the word "manufactured", the test is whether the process or operation is one that would "ordinarily be described by the words "manufacture" or "production" ": Rochester [3] , per Dixon J. By parity of reasoning, the test whether objects are "goods" is whether they would ordinarily be described by the words "goods" or "commodities". Although unsaleable items are not necessarily outside the conception of goods in s. 17(1) of the Act, it may be useful, in determining whether they are properly described as "goods" or "commodities", to consider whether they are saleable. Many objects which are unsaleable are not properly described as "goods" or "commodities". However, some objects are properly so described notwithstanding that, for one reason or another, they are unsaleable. References in cases such as Federal Commissioner of Taxation v. Riley [4] , and Federal Commissioner of Taxation v. Nimrod Theatre Co. Ltd. [5] , to the question whether particular objects are or are not saleable are properly to be understood as referring to a feature which in many cases (but not invariably) will indicate whether the objects are properly described as "goods" or "commodities".
