What it does
This Act creates a statutory mechanism allowing defined State entities to make payments to the Commonwealth that represent amounts that would have been payable as GST if (a) the constitutional rule in s 114 had not prevented the imposition of that GST and (b) section 5 of the Commonwealth GST imposition Acts had not been enacted. The Act defines who counts as a State entity for this purpose (see sec.3), confirms that such entities may take the practical steps required if they were GST-liable (sec.5), and gives the Treasurer a written-direction power to require those payments and actions (sec.6). Payments are to be made to the Commissioner of Taxation, who is defined by reference to the Taxation Administration Act 1953 (sec.3).
Mechanically, the statutory architecture has three parts. First, sec.5 is permissive: a State entity "may pay" GST-equivalent amounts and "may do anything" necessary or expedient as if it were GST-liable. Second, sec.6 turns some or all of that permissive capacity into compulsory conduct where the Treasurer issues written directions. Those directions may require payments or other actions that the State entity is authorised by sec.5 to undertake (sec.6(1)). Third, sec.6(3) makes compliance with a Treasurer's direction obligatory "despite any other Act," and sec.6(2) authorises directions to relate to events before the direction was given (retrospective effect).
The Act also contains standard preliminary provisions: a short title (sec.1), precise commencement rules including staggered commencement for particular schedule items (sec.2), and definitions for key terms (sec.3). The Act cross-references the A New Tax System (Goods and Services Tax) Act 1999 for the definition of GST and lists the GST imposition Acts it contemplates (sec.3). The Commissioner of Taxation is the counterparty to payments under sec.5.
