This provision, which is, of course, subject to contrary intention[16], may be reason enough to read s 5N as subject to a geographical limitation. Whether s 12(1)(b) has this consequence would require consideration of s 31(1) of the Interpretation Act and its provision that Acts are to "be construed as operating to the full extent of, but so as not to exceed, the legislative power" of the State Parliament. But as was explained by Kitto J in Kay's Leasing Corporation Pty Ltd v Fletcher[17], the question of geographical limitation arises regardless of the engagement of a provision such as s 12(1)(b) of the Interpretation Act[18]. Section 12(1)(b) does not identify which of the several possible elements of s 5N is to be read as a "matter or thing in and of New South Wales". So, is it the reference to a "contract" in s 5N that is limited? Is the reference to a "contract" to be read as limited to contracts that are made in the State, or to contracts, wherever made, whose proper law is that of the State? Or is there some geographical limitation to be applied by reference to the compound notion of "a contract for the supply of recreation services"? That is, is s 5N limited to those supplies that are to be made in New South Wales?
