(1) The annualised MTAWE figure for a relevant June quarter means the figure that is 52 times the amount set out for the reference period in the quarter under the headings "Average Weekly Earnings--Trend--Males--All Employees Total Earnings" in a document published by the Australian Statistician entitled "Average Weekly Earnings, Australia".
(2) The relevant June quarter , in relation to a child support period, means the quarter ending on 30 June of the last calendar year ending before the child support period begins.
(3) If at any time (whether before or after the commencement of this section), the Australian Statistician publishes the amount referred to in subsection (1):
(a) under differently described headings (the new headings ); or
(b) in a document entitled otherwise than as described in subsection (1) (the new document );
then the annualised MTAWE figure is to be calculated in accordance with subsection (1) as if the references to:
(c) "Average Weekly Earnings--Trend--Males--All Employees Total Earnings"; or
(d) "Average Weekly Earnings, Australia";
were references to the new headings and/or the new document, as the case requires.
(4) For the purposes of this section, the reference period in a particular quarter is the period described by the Australian Statistician as the pay period ending on or before a specified day that is the third Friday of the middle month of that quarter.
(5) If:
(a) the Australian Statistician publishes the amount (the later amount ) referred to in subsection (1) for a relevant June quarter; and
(b) the later amount is published in substitution for such an amount for that quarter that was previously published by the Australian Statistician or that was applicable because of subsection (7);
the publication of the later amount is to be disregarded for the purposes of this Act.
Determination of amount by Minister
(6) If the Australian Statistician has not published the amount referred to in subsection (1) for a relevant June quarter before the end of the first 30 September after the end of that quarter, the Minister may, by legislative instrument, determine an amount for that quarter.
(7) If the Minister does so, the amount referred to in subsection (1) for that quarter is taken to be the amount determined in the instrument under subsection (6) for that quarter.
Note: The annualised MTAWE figure for that quarter will be 52 times the amount that is taken to be the amount referred to in subsection (1) for that quarter.
