What it does
This Act sets out only commencement and consequential/transitional machinery for amendments and repeals contained in its Schedules. The operative, textually expressed effects are narrow and mechanical.
First, the Act provides its short title (s 1). Second, it fixes commencement rules for specific provisions by reference to a commencement table (s 2). That table records that sections 1 to 3 and anything in the Act not otherwise covered by the table commenced on the day the Act received Royal Assent (the table records that date as 1 April 2005). The table also records that Schedule 4 commenced at the same time as section 6 of the Australian Communications and Media Authority Act 2005, with the date recorded as 1 July 2005. The Act explicitly warns that the table relates only to provisions "as originally passed by the Parliament and assented to" and that it will not be expanded to deal with provisions inserted in the Act after assent (s 2(1), table note).
Third, the Act prescribes how each Schedule operates. Section 3(1) states that each Act and each regulation specified in a Schedule is amended or repealed "as set out in the applicable items in the Schedule concerned," and that any other item in a Schedule has effect according to its terms. Section 3(2) preserves the Governor‑General's power to amend or repeal any regulation amended under subsection (1). Section 3(3) confirms that regulations amended under subsection (1) are "taken to still be regulations." Finally, s 2(2) records that Column 3 of the commencement table contains additional information that is not part of the Act and that information in Column 3 may be added to or edited in any published version of the Act.
Mechanically, therefore, the Act does three things and only those things: provides a short title (s 1), establishes commencement mechanics and records certain commencement dates (s 2 and its table), and directs how the Schedules operate to amend or repeal other Acts and regulations while preserving the Governor‑General's powers and the status of amended regulations (s 3(1)-(3)). The Act contains no operative substantive regulatory provisions, no standalone duties beyond the operation of Schedules, and no penalties or enforcement regime within its own text.
